Often it is not possible to capture the beauty of underwater life with normal camera, but thanks to underwater digital camera, now you can explore the marine life. An underwater camera is a special designed digital camera used for still and video photography to capture the amazing flora and fauna of marine life.
You can capture the still images of sea life or can shoot while scuba diving. Safely protected with waterproof casing, these digital cameras are designed to be fully submerged underwater and withstand any surrounding pressure. The smaller models of underwater cameras are normally ideal for up to two hundred feet to four hundred feet while the bigger digital cameras are made for deeper water regions.
As compared to film-based underwater cameras, the underwater digital cameras are much better since they don`t run out of film. Yon can also delete any bad shots or change to a lower resolution picture mode in low-light conditions. No more fuzzy backgrounds and edges as seen in film underwater cameras, with their wide-angle photography, underwater digital cameras delivers sharper images.
Available in all sizes, shapes and film format, many underwater digital cameras also come with viewfinder feature which helps in picture adjustment for photography. With some nice prints, the underground digital camera produces better images which are really helpful for amateur photographers.
However the underwater digital camera is not only meant for deep-sea divers. Many underwater digital cameras available today can also be used to take quality pictures on dry land in harsh climatic conditions like snowfall and severe rains. Adorned with multi-flash function, color correction filter and macro lens, the underwater digital camera offers superb image quality. Just like normal digital camera, this underwater digital camera also comes with 15MB of sufficient memory along with the storage, editing and manipulation software.
If you wonder which model of underwater digital camera to choose, what features to consider, then here is a briefly discussed guide on the features of some prominent underwater digital camera models.
This compact model is for those who want an easy-to-use and lightweight underwater digital camera. With 10x optical zoom and MPEG-2 format up to 10 Mbps, this is one of the best digital cameras available for video recording. However, with only 0.3MP 640x480 still imaging capability, the still imaging options are basically non-existent in this new model.
Pentax Optio W30:
One of the pioneers in underwater digital camera market, the current Optio W30 comes with 7MP with ISO1600 and 3x optical zoom image recording feature. Supported by both SD and SDHC, Videos in this underwater digital camera is of 640x480 in MOV QuickTime MJPEG format.
Sanyo Xacti VPC-E1:
This is the one of the best designed underwater digital cameras for up to 5feet depth of water. With 4GB card, and MPEG-4 AVC/H.264 at 640x480 powers, the Xacti E1 allows shooting with an approximate record time of over 5 hours. For still images, this digital camera offers a solid 5x optical zoom with a 6MP CCD at up to ISO1600 power. One special key feature of this underwater digital camera is the flip out view screen which saves you from the risk of bumping in with underwater objects while swimming around.
Olympus SW series:
At 10 Megapixels, ISO1600, and a 3.6x optical zoom feature, Olympus may also be one of the most well rounded underwater digital cameras. With an underwater depth up to 6.6 feet, this is the deepest water digital camera on the list.
Intova IC-700 7.0MP digital camera with underwater housing:
Available in an affordable price of around $300, this underwater digital camera features 7 megapixels, macro mode and an in-built flash that can reach up to five feet underwater.

Black and White Photography - Still Most Creative Form of Photography
You would rarely find a person who does not like photographs. Photographs of people, nature and wild life attract almost everybody. With the advent of digital cameras it is now easy to catch moments in frames forever.
During the early stages, black and white photography was the only way to capture photographs. Experimentation with color photography started around 1861. Modern color photography evolved gradually.
However, there is no reason to think that color photography has replaced black and white photography completely. Black and white photos are still very much there and there is no clue for them to vanish in near future.
Black and white photographs bear an artistic and creative look that attracts people. Color photographs are often mirror copies of what we see around. However, when it comes to present an idea, a mood or a philosophical thought, photographers prefer going black and white.
Photography - a rewarding hobby
Ask people about their hobbies; many of them would answer that they like photography over anything else. It is an interesting, challenging and rewarding hobby! You would hardly find an individual who would not carry a camera during festivals, family functions, social or corporate events or while traveling.
And the reason is simple. Photographs let you cherish old memories. When you leaf through the pages of family album, you go back to the time when the snaps were taken. Small memories associated with the pictures come in mind. The person must be stone-hearted who does not get emotional to see old family photographs.
Black and white photos are the true elements to make one nostalgic. The effect of light and shadow becomes prominent in bicolor photography. A lot of people feel that close-up portraits look great in black and white. Facial expressions are caught perfect in black & white photographs. It is often said that tears are better expressed in black and white!
Black and white travel photography is equally popular among travelers and nature lovers. Wild life photography and travel photography are appreciated and accepted whole wide world. Photojournalists and travel photographers carry their cameras always as the picture perfect moment might appear before them any time.
Animals, flowers, trees, rivers, night sky, nature, heels, people, regional festivals, tribal life and sun rise and sun set are the most common subject of travel photography. Black and white travel photographs and wild life photographs are often placed in auction and sold at high price.
Black and white photography is one of the popular forms of art and will continue to be so for years to come.

I'm still progressing through your books (on chapter 10 of Digital Photography Success) and I've also just bought a new camera which is far more advanced/complicated than my old one (it's a Fuji Finepix S9600).
However, at least as I'm getting to grips with it I understand the balance between shutter speeds/aperture and settings like the EV correction on the camera haven't confused me. I've been experimenting with it most days this week and went to the Q1 tower at Surfers Paradise today where I took a few nice landscape shots (as well as quite a few average shots!). However, the camera coupled with my new knowledge I've learned on your course has made a dramatic difference - so thank you.
I've also re-tried a few things having read your book. Up until now my efforts at macro photography have usually been pretty poor but this week has seen a big improvement in this area. Another area concerned shots of the moon this week but in general the moon was either over exposed or its surface was lacking real clarity. I've previously tried this with my old camera and also had pretty average results but I then discovered the sections on photographing the moon in your "Five most popular scenarios" book and now understand what I'm doing wrong - I'll let you know how I get on with my next efforts.
In addition to my efforts, my younger Calum (12), has also decided to start reading through your books, he's claimed my old camera as his own and is taking shots of just about everything he comes across. So I guess you can genuinely claim that you've fired up a bit of enthusiasm for photography in my household!
I'll keep in touch as I work my way through the rest of your books and if I come across something I'm not sure about I'll ask you.

Digital Photography Success!
It was only a few short years ago that digital photography was considered little more than electronic gimmickry. A cute little electronic box that could instantly save photos into digital format that could be viewed on your desktop, but nothing of the kind of quality that could compete with real photography. In fact, sophisticated electronic cameras such as the Nikon 6006 or the 8008, and Canon's Elon SLR's (single lens reflex) cameras were just coming into their own in the early 90s.
As digital cameras began appearing on the scene in the latter to late 1990s they were nothing more than novelties capable of producing a picture about 1/2 the quality of film cameras at best. Then high resolution digital SLRs finally burst onto the scene but were so expensive that most professional photographers were unable to afford them. Most photographers simply used film cameras, scanned the slides or negatives and then they were able to obtain a high quality digital photo.
The first affordable digital SLR that I saw was the Canon Digital Rebel in 2003 or 2004 and sold for $999 with a special digital lens. The special digital lens was necessary due to the small sensors that these cameras used causing a 17-50mm lens to operate at about a 1.5 magnification making the lens like a 28-70mm zoom on a normal camera.
These new digital SLRs approached film quality and gave the added satisfaction of being able to critique your work right away. You could make adjustments right in the field without having to wait for your prints to come back from the lab.
When I first got into photography I studied all the latest techniques that I learned in magazines like Popular photography. Then I took several rolls of film, delivered them to the lab and picked them up later only to find that the pictures just didn't look the scene I just shot. Little did I realize when I first started shooting that even the best camera lens can only see about 1/10 the color range that the human eye can see. This is why you can see in the dark, but the camera lens can not. More about night photography later.
So now you have your instant pictures to view, but the process doesn't stop there. With digital pictures you still have to download them to your computer and load them into an imaging program such as the one that came on a disk with the camera or a more sophisticated program like Adobe Photoshop. Your camera's included software is limited but quite adequate for the average snap shooter.
So in review to get started in digital photography you need:
1. A decent camera (preferably a SLR with interchangeable lens).
2. A computer with adequate memory and storage.
3. An imaging software program.
Now you are ready to begin the basics which are outlined in some of the available electronic books available in pdf format such as Digital Photography Success!
