Underwater cameras have come a long way since they were first made available to the average amature photographer and with more and more features being integrated on these devices they are becoming more and more fun!
Underwater and extreme photographs are wonderful things, providing you can use your camera underwater. If however you are unsure about whether your camera has the waterproof rating or not i would advise you to either consult the user manual that came with the device or check the manufacturers website as to avoid plunging youre brand new gadget under the water and breaking it!
There are two ways of going about taking photos underwater you can either buy a waterproof digital camera or you can purchase an underwater housing for the camera you have her are some instances of what i think are the best underwater cameras and the accessories you can purchase for them.
CANNON
Cannon offer a lot of underwater housing units and they are manufactured specificaly for their own brands and models of digital cameras. The good thing about Cannon is that you can also visit their web site and find out additional information on underwater camera care which in my opinion is a nice little feature.
EWA_MARINE
Again this company offers housings for for digital cameras but this company has the advantage that they make housings for a range of different makes and model of camera you can use the companies website to determine if they make appropriate housings for your digital camera.
RECENT BREAKTHROUGHS IN THE BEST UNDERWATER DIGITAL CAMERAS
there are many reasons why the best underwater digital cameras are getting better and better the field of ocean optics is coming along in leaps and bounds and this i think partially attributes to some of the following developments.
Firstly is affordability, high quality cameras have come down alot in price these days and they now support a wide range of inexpensive and rather quick image processing software and hardware add ons.
they now have high repetition rate, advanced detector designs and a range of moderate power lasers which all make the performance of the two dimensional and three dimensional imaging systems hundreds of times better than thier predecessors.
The digital compression schemes they have now make for top quality standardizations so the transfer rate is now even quicker for streaming and the storage requirements have been radicaly reduced.
The programs for simulation and modelling can now predict alot more accurately the effects that the physical ocean parameters make on the imaging systems performance under configurations that differ with geometrics.
These features only really scratch the surface of the recent breakthroughs in underwater cameras and alot of the applications of late are aimed at using conventional cameras and are for the use of monitoring them long term and observing where the needs of the collection of video imagery can be used to give measurements and image scaling and alot of these systems benefit from the camera or device being able to operate continuously for a long time unattended as for use with the fimling f wildlife and other marine phenomena that begs for than just one picture to be taken.
