We present some useful and practical tips from been there, done that professional photographers who have taken to practicing their art underwater for a reason, whatever the season and bring you these handy hints to excel in a specialized segment of nature photography, here! Take a look –
The nature of underwater photography has undergone a vast sea-change (and there truly is no pun on that) in the last 3 decades: while the mid eighties saw photographers taking to the waters with video and still camera lenses covered with plastic to prevent seepage entering and spoiling their sensitive parts, the nineties saw the development of water-resistant lenses and later water-proof cameras that enabled one to capture moving shots of sea-creatures and underwater life along with flash-enabled lighting. Moving to the year 2000 and beyond, there were lots of improvements in the field of science and technology, which yielded great results for the field of Digital photography; for the whole new burgeoning world of amateur and hobby photographers who were also keen on sea-diving and other water related sports, this meant being able to take photos in hitherto unexplored places and in a candid manner!
Being able to go where few have gone before and get consistently good results from advanced features contained in latest underwater digital cameras supported by long-life batteries, artificial lighting that enhances the focus of underwater subjects and practiced photography skills are some of the advantages modern photographers of today have for themselves.
Underwater photography is now a singular segment warranting its own special techniques, equipment and group of professionals. Apart from naturalists and botanists studying underwater plant species and animal-life, even historians studying wrecks and anthropologists studying life-forms and people giving birth underwater etc are groups that have interest in underwater snapshots besides of course, scientists and biologists who photograph and study marine life.
To ensure your underwater photographs turn out better than usual, there are a few points you’d do well to remember:
• Invest in a basic digital camera meant for underwater photography as you can spoil your normal digicam if you just cover it with plastic to use underwater. Underwater cameras come equipped with special parts that prevent it from getting spoilt even when submerged in murky waters and still manage to give good shots in limited natural light, depending on their quality.
• Always follow the guidelines given with the underwater camera for best results gained by the device as straying from these can result in causing major damage to your precious piece of photographic equipment and be hard to repair, thus cost you dearly.
• Always remember that the deeper you go into the waters, the poorer light conditions you will have to face, so learn the techniques of underwater photography as best as you can to be able to use white (natural) light or some type of artificial ones to counter this issue.
• You can avoid using zoom feature when taking shots underwater and turn off flash wherever possible so the quality of photos is higher and not blurry, which is what it tends to be when flash is used underwater.
• Check for warranty of your underwater camera and do so at the shop if possible – submerge it underwater to check for leaks and get it replaced instead of waiting to try it out on an expedition and then getting disappointed if it doesn’t measure up and ruins the fun of taking underwater shots and your mood.

  You are able to create digital pictures in three different types of file formats: JPEG, TIFF, and RAW. Each file format has its good qualities and bad qualities. It is the photographer’s choice to see which file formats to use that works best. If you want to send an image through e-mail, the best format would be JPEG. If you like creating large prints and like optimizing the color that best suits you, shoot in RAW, or you may prefer TIFF if you are working with an advanced desktop publishing software. What are these formats and what do they stand for? JPEG is an acronym for Joint Photographic Experts Group; this is the gathering of photographers who met to discuss formats. JPEG is used a lot in e-mails because it is a compressed image file format and has a smaller size in megabytes unlike the other formats. A disadvantage is if the image is compressed too much the photo quality may seem noticeably damaged. TIFF stands for Tagged Image File Format. This is a file format that was created in the 1980’s as the standard format used across multiple platforms. Once the TIFF was introduced many people have improved upon it and now there are around fifty variations. Also the TIFF format can handle color depths between 1-bit to 24-bit. RAW files are unprocessed images that are generally referred to digital negatives. RAW mode doesn’t compress the images and another disadvantage of RAW is that it uses a lot of memory on your card. An advantage is that since this format is unprocessed you can have more control over color corrections and processing on the computer. If you plan on making large prints this is the format to use. More expensive D-SLR cameras have this feature and come with editing software allowing you to open RAW files. Then you are able to edit them and save them to JPEG or TIFF file formats. Now having a better understanding of file formats you are able to be more creative in your digital photography.
