A Trip To The Thai Jungles With The Olympus MJU1050SW and Canon EOS D60

December 15, 2008

The steaming glutinous rice burnt his tongue and Adrian lunged for the water jug. The diners around the wooden table concealed their sniggers and Adrian felt a little better, for his sudden movement caught the attention of his fellow diners. He was having a traditional Kantoke dinner in a tiny restaurant that seemed out of place in the crowded streets of Bangkok. Very soon the ice was broken and conversation flowed.

‘I’m a globe-trotter’ said Adrian, slurping his Tom kha gai ‘I don’t just travel places…I capture them in my cameras to be treasured for eternity….I’m headed to Uthai Thani now. I’ve arranged for a camp in a wildlife sanctuary there. ’ ‘Oh, to the Huai Kha Khaeng Wildlife Sanctuary?’ asked a bearded old man. ‘That’s a biodiversity haven…It’s a paradise’ ‘Yes’ said Adrian, I’m all geared up for yet another trip to the wilderness’ He unzipped his back-pack to reveal his comrades for the adventure – Olympus MJU1050SW Digital Camera and Canon EOS D60 Digital SLR.

‘The Olympus MJU1050SW, my friends, is a 10.1 megapixel digital camera, which is shockproof, waterproof and freeze proof!’ Said Adrian to the five men around the Kantoke banquet. ‘And this is the 6.3-megapixel Canon EOS D60, which is Compatible with all Canon EOS system lenses. I’m looking forward for some fine shots of wildlife with this one’

The men took turns to admire Adrian’s digital gadgets and were full of praises for both the gadgets. It was time to leave and Adrian’s heart was heavy, for now a warm camaraderie had formed between them. With an Advanced Face Detection of up to 16 persons, his Olympus MJU1050SW shot a picture, which when seen in the HyperCrystal II LCD, revealed 6 smiling faces tracked perfectly within the frame. It was yet another picture, which went straight to Adrian’s heart. He now had a special album, composed of photos of friends he had made during his trips around the world, and this shot he mused, will indeed be special.

Uthai Thani, a place known to be once inhabited by prehistoric people, was about 219 kms from Bangkok. All through the bus journey, Adrian wished that Tia was there with him for this wild sortie.

The abundance of natural resources was the first thing that Adrian noticed, the minute he set foot in Uthai Thani. He immediately took out his chic Olympus MJU1050SW and shot some sharp pictures with the high-precision 3x optical zoom. The Sakae Krang River, which formed the backbone for provincial trade provided some interesting pictures. Even as the afternoon sun was at its brightest, the assiduous life of the raft residents was caught with panache, thanks to the Shadow Adjustment Technology of the MJU1050SW.

Lunch was an elaborate affair and Adrian enjoyed it immensely. He especially relished a spicy pork sausage called ‘name’, which was a regional specialty. Before leaving for the sanctuary, Adrian decided to visit Wat Tha Soong, a sprawling Buddhist temple complex. He took another bus to reach the temple and this time, he had his Canon EOS D60 at the ready to capture the brilliance of the temple.

What a place that was! Spread across hundreds of acres, the temple housed thousands of Buddha images in different postures according to Buddhist scriptures. It was a field day for Adrian. He flourished his D60 across every image he could see. In the Continuous Shooting mode, the D60 shot 17 large images at up to 3 frames per second. Combined with a shutter speed of over 1/250, the D60 produced some splendid shots.

After the spell-binding experience at Wat Tha Soong, Adrian took a night bus to the Huai Kha Khaeng Wildlife Sanctuary. It was past mid night when he reached the sanctuary. After a refreshing sleep at the Huai Mae Di Ranger Station, where he had pre-booked for his stay, Adrian was up before day light all set to capture the Thai wilderness in his Olympus MJU1050SW and The Canon EOS D60.

Adrian trekked to Namok Hin Lat, a waterfall near the Ranger Station. He captured the multi-layered waterfall with the Canon D60's TTL auto-focus that came with three focusing points. However, Adrian was not extremely satisfied with the D60’s auto-focus, as the cascade was not captured with the sharpness that he desired.

He then decided to try a shot with his Olympus. Using the high-precision 3x optical zoom, he shot a pleasant shot of the waterfall, which was shot with ease, for he shot with reasonable clarity without moving a single step forward. The vigour of the fall was captured even in direct sunlight and Adrian found it easy to compose and shoot due to the extra-wide angle and anti-glare technology of the 2.7’’ HyperCrystal LCD.

The breeze from the rattan forest surrounding the waterfall pulled Adrian with invisible strings and he decided to mellow out a bit among the shady trees. Along the path of the short hike, Adrian discovered a wild flower in full bloom that exuded a wild fragrance. The daring display of colours thrilled Adrian and his Olympus was busy again, with the TruePicTM III Image Processor, the blood-red flower was shot with true-to-life colour.

The leaves of the rattan forest, known to change colours in different seasons, were a beautiful shade and it was the D60’s turn now. Adrian discovered that the lens of the D60 had two stabilization modes, the first to capture stationary targets and the second, to capture targets that are moving horizontally. He used the first mode now, and shot the brilliantly coloured flora and was delighted with the clarity.

Adrian decided to break for a quick lunch, for the hike left him exhausted. He lounged a while at the Ranger Station and prepared himself for a four hour long hike along the Khao Hin Daeng Nature Study Route. He put on the hiking boots that he had saved especially for this particular hike, for a four hour hike required the perfect shoes, the perfect clothes, the perfect mood, but most importantly for Adrian, the perfect digital camera.

The Khao Hin Daeng Nature Study Route provided the perfect platter for a nature-lover and for a photography enthusiast like Adrian, it definitely was Eden. The pristine air and the lush, wild vegetation did wonders to Adrian’s photographic skills. The Nature Study Route provided for a variety of vegetation that included the deciduous forest, deciduous dipterocarp forest, mixed deciduous forest, and dry evergreen forest. With the Perfect Shot Preview of his MJU1050SW, Adrian viewed the effects of various settings including zoom, exposure, white balance and metering before taking the shot. This provided him an extra edge over the camera settings and it put him at ease.

Along the route, was a marsh that was surrounded by a mess of smelly twines and muck and Adrian decided to take a closer look. He stopped short within a few steps, for a sudden movement caught his attention. Coiled around a decomposing branch was a Wagler's Pit viper. It took a few seconds for Adrian to realize the importance of such an encounter, for he was now facing one of the most deadliest snakes in Thailand. Without a moment’s hesitation, he took several shots with his D60 in the "shooting priority mode," so that he could view the pictures in between shots. Adrian was at arm’s length to the snake and he felt like Steve Irwin, for he was so close to the unpredictable, yet so bold. He had never been so daring!

He stood there, shooting the beauty with a reticulated pattern of greenish tint, until it moved on. Adrian suddenly realized that he was almost knee-deep in the marsh. A smooth body of a marsh Iguana slithered against his feet and he leaped with a slurpy noise to run for his life! And lo! He dropped his MJU1050SW in the water amidst all the commotion. But his MJU1050SW was as sturdy as a cowboy, for it was shockproof up to 1.5m and waterproof up to 3m.

Though Adrian was a bit shaken by all that running and the sudden pump of adrenalin in his veins, he was not a bit shaken in spirit. And there is good reason for that, for there still exists a good number of English men who thinks monitors are venomous. Then this one was a giant, even if not as big as a Komodo. He hiked on, and reached the sight-seeing point, Pong Thian. He rested his tired legs for a while and fantasized about shooting a tiger or a leopard when a shrill bird-cry caught his attention. On closer inspection, he identified it to come from a red-breasted parakeet. All thoughts of shooting tigers and elephants left him and Adrian readied his D60 for some bird photography.

His Canon EOS D60 6MP Digital SLR, which came with interchangeable lenses that supported all Canon EOS series lenses presented many avenues to experiment. Adrian used a Phoenix 100mm f3.5 macro lens and panned the camera along the motion of the bird. It was indeed an excellent camera to shoot birds, but on rare occasions, it also produced some blurred images. Adrian even shot some pictures of the elegant and lineated barbet and was proud that he was evolving as a decent bird photographer.

Adrian also shot some wild orchids along the way with his Olympus MJU1050SW Compact Digital Camera and he found the TAP Control Menu very convenient, as he was spared the press of a button every time. It was pitch dark when he walked back to the Ranger Station. He took a different route, that was less used. His mood was quite dull, for his flight was due the next day. He couldn’t imagine living amidst the hustle and bustle of London after such a lullaby in the lap of mother nature. Just then, a sound behind the near-by bushes distracted him. He looked right into the very spot and thought he saw a flash of bright orange. His heart raced and he tugged at his D60. But then, it was gone in the wink of an eyelid. Was it a tiger? Well, Adrian never did find out!

Focal Length Facts

December 14, 2008

Definition of Focal Length: -

When many parallel light rays strike on a lens, they tend to converge at a particular point at the back of the lens. This point is known as the Focal Point. The distance from the middle of the lens to the focal point is known as the Focal Length. In the case of digital cameras, focal length is defined as the distance (in millimetres) between the optical centre of the lens and the image sensor.

Importance of Focal Length: -

Focal length is used to determine the magnification available through the camera. For example in case of a 35mm camera, a 50mm lens is required to get a natural view of the subject. The magnification of the objects increases in direct proportion with the focal length and as the focal length decreases, the objects appear farther away, however more area is covered. Focal Length is mentioned in terms of 35mm-lens length equivalent. This is because the traditional wide usage of film based cameras, where many  are acquainted with the focal length that is required to project images on a 35mm film.

Now let us compare the actual focal length of a 1.3 mega-pixel digital camera with that of a 35mm film based camera.

For Example

  • Let focal length = 5.4mm; in a film based camera it is equivalent to 35mm. At this focal length, objects look small and far away. However it can be used to take wide coverage area shots like landscapes, groups of persons, etc.

  • Let focal length = 7.7mm; in a film based camera it is equivalent to 50mm. At this focal length, objects look at about the same distance as they would appear to the naked eye. This is used to capture normal pictures of people.

  • Let focal length = 16.2mm; in a film based camera it is equivalent to 105mm. At this focal length, objects look magnified. This is used to capture Telephoto shots, as well as close-up shots.

Types of Lens: -

  • Wide-Angle Lens: - A lens with the focal length less than 50mm or 55mm is considered as a Wide-Angle type of Lens. They are best suited for taking wide area images.

  • Normal Lens: - A lens with focal length of 50mm or 55mm is considered as a Normal type of Lens. They are suited for natural images.

  • Telephoto Lens: - A lens with focal length greater than 50mm or 55mm is considered as a Telephoto type of Lens. These are suited for close-ups.

Image using a Wide Angle Lens with focal length of 24mm Image using a Wide Angle Lens with focal length of 35mm
Image using a Normal Lens with focal length of 50mm Image using a Telephoto Lens with focal length of 100mm
Image using a Telephoto Lens with focal length of 200mm Image using a Telephoto Lens with focal length of 400mm

As the sensor sizes of compact cameras are of different sizes, the focal length of a camera is often defined in terms of its magnification power. This is directly related to the focal length, e.g; for a 3x zoom camera, the focal length works out between 58.mm to 17.4mm. Thus a shorter focal length gives more area coverage, while a longer focal length provides with more detailed images.

Nikon D60 and Sony Cybershot DSC H2 Combines to Explore Nigeria

December 1, 2008

The sky was overcast and the air was heavy. Two people trundled in a sturdy Gypsy along a bumpy road, each engrossed in a world of their own. Adrian, who felt unsure of what he was doing, from the moment he landed in Nigeria, now felt a lot better. The 16 ounce Nikon D60 10MP Digital Camera was slung across his shoulder and Adrian felt reassured.

He looked around to see Tia gazing out the window and reminisced about their meeting at a down town pub in London. She was a very interesting person and Adrian discovered that she was a nature lover. After an interesting conversation over beer, Adrian asked her out the next day.

But Tia was not the type to go sailing on a yacht or sit huddled in a movie theatre. When she suggested he visit her country Nigeria, Adrian hesitated. An adventure to Nigeria in this time of the year? But Tia dispelled his apprehensions. They started that weekend and Adrian made sure he took his Nikon D60 Digital Camera. He knew it was just the right camera to capture the untamed Nigerian wilderness. With a remarkable 10.2-Megapixel DX-format Nikon Picture Quality and AF-S DX NIKKOR 18-55mm f/3.5-5.6G Vibration Reduction Image Stabilization Lens, the D60 was the first thing that he packed.

The wind had traces of a raw scent that Adrian associated with animals. He looked questioningly at Tia. “We’re here” she said, with a smile. As they disembarked, Adrian felt his pupils widen immediately. In front of him was a stretch of dark green wilderness so fresh that he wondered if they took a shower every morning. He immediately brought out his D60 and was thrilled to use the 3-Area Autofocus that gave him a consistent subject acquisition and improved focus tracking.

Tia who was watching him from a distance, took out her Sony Cyber-shot DSC-H2 12 x Optical Zoom Digital Camera. She was a novice at digital photography, and bought the DSC-H2 in order to learn the art. The DSC-H2 didn’t come with a 3-Area Autofocus of the D60. But she was satisfied with the massive 12x optical zoom lens that was equivalent to 36-432mm on a 35mm camera. She too took some brilliant shots. However, Adrian’s Nikon D60 came with a 2.5-Inch, 230,000-Dot Color LCD Monitor with 170-Degree Wide-Angle Viewing which enabled him to magnify his image up to 19 times. And her DSC-H2 had a 2 inch colour TFT LCD monitor which had 85,000 pixels.

“This is the Drill Ranch of Afi Mountain” said Tia, starting to walk. “I have booked us a cabin with a nice view of the mountain” They checked into a spacious cabin. It was fully screened but open to the air on all four sides. From the cabin, it was possible to watch the greenery outside.”We can watch the drills climbing up to 35 meters in the trees from here” said Tia. After a meal which they had packed in their back packs, Adrian and Tia headed towards Kache Bano for the famous Walk-a-Way near the Cross River State Tourism Bureau.

Adrian didn’t know what to expect, but was thrilled all the more. He made use of the Advanced HELP Menu System of his Nikon D60 that enabled him to select an appropriate feature automatically. They were all set for the trek from the Drill Ranch camp. They captured every moment of the longest and highest canopy walkway in Africa. Him, with his Nikon D60 that now faced the dim rainforest light with a 3D Color Matrix Metering II that evaluated the scenario for brightness, color, contrast, size and position of shadows and highlights. And she, with the ISO1000 of her Sony Digital Camera for shooting without a flash in low-lighting conditions. However, some grain-like speckles were visible which, she noted ruefully were not the case with Adrian’s D60.

The canopy walkway was truly an exotic experience and Adrain thanked Tia for, he never knew such a thing existed. They lunched again from their backpacks, on frozen steak with tinned milk and Adrian sulked at the thought of the inability to eat fresh food. And Tia assured him fresh fruit once they reached the ranch. They decided to hire a Jeep to take them back to the ranch as both of them were exhausted.

During the bumpy ride back, Tia showed Adrian that her DSC-H2 had a whopping 12x optical zoom. “How can you shoot without wobbling with such long lens?” asked Adrian and Tia was ready with the answer. She said that her DSC-H2 had an anti-shake system called Super Steady Shot with a ‘wobbly hand’ button. But Adrian’s D60 did not need a button to prevent blurs, for Nikon's EXPEED Image Processing Concept optimized his pictures, shot after shot.

As dusk fell, the Afi mountain resembled an abominably huge monster, for only the silhouette was visible. Adrian decided to capture it taking advantage of the Speedlight with i-TTL Automatic Flash Control of his D60. The Speedlight feature added magic to the twilight picture. Tia too didn’t miss out on the shot as she used the mode Twilight Portrait of her DSC-H2. Though the result was not as good as Adrian’s, it was definitely good for a beginner.

After a dinner of fresh avocados and bananas which Tia had arranged from the ranch, they retired to bed. It was Adrian’s first night stay among wilderness. He didn’t sleep all night, for he lay listening to the numerous sounds of the night creatures, who demonstrated a practiced orchestra before him.

Before daylight, Adrian and Tia were up, full of plans for the day. They decided to spend the day at the ranch. The Drill Ranch at Afi was the home for orphaned chimpanzees and Drills, one of Africa’s most endangered primates. They shot several groups of chimpanzees. Adrian shot up to 3 frames per second, for as many as 100 consecutive JPEG images with his D60. All the action was captured brilliantly. Tia shot a mother chimp and her son beautifully with her DSC-H2’s Burst mode, with which she took 1.3 frames/sec for 7 shots at the 6M Fine setting. Adrain boasted of the 3 frames per second his D60 delivered and showed her his shots, they were indeed of a superior quality than her’s. “So what Ady? “ Questioned Tia I just want to learn! My DSC-H2 is a good teacher”

Ady and Tia spent the afternoon walking in the rainforest after a refreshing dip in a natural pool. It was now that Adrian captured some excellent shots with his D60. Afi Mountain was listed as an ‘Important Bird Area’ for Nigeria, and the migratory birds often roosted in the surrounding areas. He chose Landscape from Eight Digital Vari-Program Modes including Auto, Auto Flash-OFF, Portrait, Landscape, Child, Sports, Close Up and Night Portrait and shot an outstanding picture of a couple of pelicans floating regally in a lake.”I think they are lovers. Look at how comfortable they are together!” commented Tia and Adrian smiled.

Adrian assisted Tia in using the 2x digital zoom of her DSC-H2. From 5 different White Balance presets to choose from such as Daylight, Cloudy, Fluorescent, Incandescent and Flash he chose Daylight. The shot of a mysterious black bird hidden amidst a muck of twines and bushes came out splendidly. A giggling Tia named it ‘The Black Phantom’. Tia’s DSC-H2 came with 4 different colour modes - Natural, Vivid, Sepia and Black & White. She chose Natural and also used The Macro setting that allowed her to focus on the bright red mushrooms that were as close as 2cms.

On their walk back to the ranch, Adrian and Tia compared their pictures. While Ady’s D60’s shots were impeccable, Tia’s DSC-H2 had some evidence of fringing . It was visible as a line of different coloured pixels in between areas of high contrast. The D60 was indeed the better of the two, although Tia argued that the defects were less visible and the Carl Zeiss lens captured reasonably good detail.

‘‘Tia’, what does 'Tia' the term stand for?” asked Adrian as they sat in front of a warm camp fire. It’s short for ‘Taiwo’, Said Tia.” which means 'the first to taste the world'. I have a twin. I am the elder one.” Adrian felt that there could be no other perfect explanation for her name. She also led him to taste her world, the taste of which was now immortalised with his Nikon D60 .

Panasonic Lumix DMC-FX500, Take me to Switzerland!!!

November 25, 2008

The TV was bawling away in the extra large guest room of Glaernischoff Hotel achicken was blazing beyond recognition in the oven placed beside an old fashioned fireplace. Adrian sat on the couch, feasting on the complimentary fresh fruits delivered to him by the management, also surveying his brand new Panasonic Lumix DMC-FX500 Compact Digital Camera that he had acquired from a store at the Zurich Airport. The slim black camera had aluminum panels with a hairline curve on the front that glistened under the dim light. Seems as if, he wouldn’t even consider the smiling of his lucky stars on him, for his firm's choosing him to represent them in the annual summit to be taken place in Zurich, Switzerland. He was so immersed in the 10.1 Megapixel digital camera. However, he rued not taking his Canon EOS 1000D along with him to this exotic part of the world. The opportunity, how glittering it may be, definitely came in short notice. Anyway, Adrian undoubtedly has 48 odd hours of leisure, before the official sessions commence.

The major features could be easily perceived in this compact digital camera with a built-in slide-show program called Demo mode. The camera unfurled itself before Adrian, as he eyed his duffle bag mischievously. Now that he has a camera, although not as commanding as his EOS 1000D that had made even an amateur like him feel like an experienced photographer, all he needed was a place worth capturing. A postcard fluttered amongst other stationaries on the deressing table, and Adrian picked it up out of curiosity. It was an old picture of the Swiss Alps. That instant, Adrian knew what he was going to do next. The Lumix DMC-FX500 with its Leica DC 5 x Optical Zoom Lens and a large 3.0” LCD with a Touch-Screen Interface, rested modestly inside Adrian’s duffle, all geared up for a photographic expedition to the land of mountains, pastures and rolling hills, the land where one can taste Italy, France and Germany all in a single package – Switzerland.

Zürich was the easiest place to reach by plane in Switzerland. With Christmas round the corner, Zürich seemed all set to welcome the most awaited day of the year. Out in the streets, Adrian immediately pulled out his Lumix DMC-FX500. He shot everything that he could see- kids, pets and people, for everyone seemed in such good cheer. The Auto focus (AF) tracking mode came as a pleasant surprise; for it enabled tracking the subjects even after the Auto focus was set. The quality of the pictures stunned him and Adrian felt the spirit of Christmas enter him too. As the sun was slipping away into the horizon, Adrian started fancying the scopes of night photography in this part, because he had heard a lot about the nightlife of Zürich. The city came alive with its numerous clubs and Adrian decided to spent some time in the Mascotte, one of the oldest clubs in the city. With his compact camera tucked into his pocket, Adrian did not miss out capturing the rapturous mood around him. It came with the facility to record video clips for 15 minutes and Adrian simply wished it was longer.

Adrian’s smooth dance moves attracted attention and he made so many new friends and was even invited for a party in the Elm ski resort the next day, which he accepted all too eagerly. The IA (Intelligent Auto) mode took off all the responsibility from Adrian, as he left all the settings to the camera's discretions. All he had to do was touch the screen and the auto focus and exposure were set perfectly. If he experimented with something here, it was with the flash of the DMC-FX500. He shot some pictures to compare them with regular con-flash ones. On his way back to his hotel room, he never forgot to conceive the golden glow of a few grand buildings basking beneath the equally glowing Swiss night sky. He tweaked the White Balance mode of his compact beauty to Preset Night to capture the grandeur. He also shot some of the same images in Twilight Scene Mode to see if he could spoof his intelligent gadget to squeeze out some better images. However, the he did not practically get anything worth mentioning out of this experimentation.

The Elm ski resort was just an hour drive from the airport. It was the prefect place and time for a beginner like him. He contemplated, musing over the overcast conditions that the 'Snow' White Balance Preset mode would come handy sooner than later. His friends from the club were already there, all geared up. The Swiss ski resort of Elm had direct access to 35km of downhill skiing, and Adrian had the time of his life. Since, the touch screen of his camera featured a high-resolution Intelligent LCD, which automatically controls the brightness at a total of 11 fine steps by detecting the surrounding lighting condition, the irresistible snow cover was captured with precision. Adrian took some memorable shots there with his friends and the Advanced Intelligent Auto Mode gave him various shooting-assist functions. The Intelligent Scene Selector set the appropriate scene mode by automatically selecting it from the most frequently used scene modes, such as Portrait, Scenery, Macro, Night Portrait and Night Scenery. It was an unforgettable day and Adrian knew it was more so, because of his Lumix DMC-FX500.

Adrian bid farewell to his friends and spent the next day strolling around Zürich, which housed more than 50 museums, out of which many were devoted to art. He visited the Rietberg Museum and admired the display of some non-European artforms from places, such as Africa, India and China. The famous Swiss National Museum was nothing less than a goldmine for a photographer, and Adrian got a good chance to experiment High-Speed Burst shooting mode, with which he shot about 6 shots per second and the Macro Focus mode that helped him conceive the tiniest of niceties exhibited. The day wore on but the DMC-FX500 did not, for Adrian shot the magnificent museums without using a flash, thanks to the some optimum ISO standards and the DMW-BCE 10 Li-Ion battery. The next day, Adrian left for Brig, keen for a walk through the Alpine passes. He first visited the famous Stockalper Palace, which the local people spoke of with pride. He learnt that the ancient building was built in the 17th century by Kaspar Stockalper. The slim camera assured minimal distortion even at its 25mm wide end, as Adrian shot the palace from various angles, and was delighted at the output.

Just beyond the city gates was the Simplon Pass, through which Napoleon built a road in the 19th century to move his armies. The pristine Alpine breeze played across his face and Adrian was awed at the incredible might of nature around him. He settled in a cozy inn and shopped in the baroque Bahnhofstrasse. He found his pockets emptying faster than he could imagine but he didn’t mind, for he wouldn’t leave Switzerland without a Rolex and an original Swiss army knife. Adrian spent the night peacefully in an inn, where he enjoyed watching all of the still and motion pictures in stunning HD quality taken by his DMC-FX500 by connecting the camera to the TV via an optional component cable (DMW-HDC2). He laughed his head off, watching the antiques of his friends at the ski resort. He even added names and dates to his pictures using the Title Edit function. He explored the camera further and admired the Hybrid Control System that combines joystick control with touch-screen operation. Adrian slept peacefully that night, after feasting on a slab of splendid Swiss chocolate.

December 6th is an important day for the Swiss, for it explained the feast of St. Nicholas. Adrian spent the day among school children in Glarnerland who paraded through the village, ringing and jingling bells of all sizes signaling that a gift was expected. Adrian captured the brilliance of the parade splendidly with his camera. A trip to Switzerland would be incomplete without a trip to the Alps. After a fairy-tale train journey up the mountains, Adrian discovered that when the picture size was set to 3 Megapixels or larger, the photo is automatically resized to 3 Megapixels and was delighted to capture the Alpine magnificence. After a short trek up a slope, which Adrian managed with difficulty, gasping for breath, he cursed himself for climbing up that high instead of dozing off in the inn. But, a single breath of air changed his mind. When he looked around, he realized he had strolled off into a haven of rolls and rolls of flowers nodding softly in the wind. He felt ecstatic and switched his camera to High-Speed Burst shooting mode and shot till his memory card was full.

He laid on the green pastures and spread his arms wide, his eyes feasting in the green brilliance before him, with his DMC-FX500 placed on his chest. Suddenly, Adrian thought he saw a little girl hopping towards him from the snow-capped peak, a herd of goats at her heel and a goat-herd running behind her calling ‘Heidi! Heidi!’ He grabbed his camera in an instinct and laughed on the illusion– if only the Panasonic Lumix DMC-FX500 10MP Digital Camera could capture his imagination too!!!

Technology Behind Canon’s ‘DIGIC-III Processor’

November 24, 2008

DIGIC Processing technology was introduced by Canon, which it uses in all its models. This Image processor uses signal processing to augment the picture quality, as well as the image processing speed.

Evolution of DIGIC Processors:-

Canon had set its R&D team to develop a technology that could change the way the images were produced. It was on the lookout for a technique, using which the processing speed, the automatic focus and the image quality could be improved. The outcome was the development of the Digital Imaging Core (DIGIC) technology by Canon.

There is an image sensor in the digital camera, which converts the light that enters the camera through its lens into electrical signals. Now a Digital Image Processor is a technicality that removes the noise from these signals and generates images with natural colours and realistic effects. The DIGIC is an image processor that reduces the false colours and moiré patterns in the pictures and cancels the noise that is generated during long exposures.

The original DIGIC was used on the Canon S1 IS and other cameras. This technology was used to improve the image quality and reduce the processing speed. However, it consisted of three separate chips: a video processing integrated circuit, an image processing integrated circuit, and a camera control integrated circuit.

The DIGIC II; unlike the initial DIGIC, was all about a single chip, thus the design becoming more compact. This new version was enhanced by the addition of a large buffer and faster processing speed. It uses a Double Data Rate Synchronous Dynamic Static RAM (DDR-SDRAM), which improves the start-up time, as well as the Auto-Focus speed. DIGIC II also improves the colour, white balance and sharpness. This technology is used in Canon EOS 400D Digital Camera, Canon EOS 5D Digital Camera, etc.

The DIGIC III processor is the advanced version of the DIGIC II processor. It has all the above mentioned qualities. Additionally, it can extend the battery life, deliver better quality images, and improve the operating speed as well. It also provides for a faster interface to the SD card memory. It also provides Face Detection Technicality, using which it can track about 9 faces in the frame and adjust the exposure, focus and flash, and provide proper lighting effects to produce explicitly realistic images. It also helps in improving the LCD screen resolution.

DIGIC III Processor:-

The circuit board of DIGIC contains a x86 compatible processor, a Datalight ROM-DOS operating system and the image processor. The DIGIC III processor consists of an embedded 32-bit ARM architecture processor.

DIGIC III Image Processor enhances the performance of the digital cameras in the following areas:-

•    JPEG Compression or Expansion

•    Memory Card Control

•    LCD Control

•    Video Processing

DIGIC III uses Advanced Noise Reduction Technology, due to which high light sensitivity can be produced. The cameras with higher light sensitivities are capable of capturing images in low light conditions with no loss to image quality and clarity. A higher light sensitivity also ensures faster shutter speed, thus reducing blurs in the images, or in fast moving pictures that refer to sports events or wildlife in action.

DIGIC III Processor has a superior processing speed, accurate auto-focus functionality, a fast camera response and continuous shooting capability. Its rate of operation and accuracy of colour reproduction, enables it to be used in Professional EOS Cameras; the Canon EOS 1000D Digital Camera, Canon S5 IS, etc.

Canon’s DIGIC technology is considered as a revolution in the digital camera industry and it emphatically displays Canon’s leadership in this industry.
