I Must Be Crazy To Be Spending So Much Time With Digital Cameras
I may be stating the obvious here. Especially on your first dive with your expensive Canon SLR and your brand new case. But, as soon as you enter the water, check the camera housing for leaks. Especially around any seals and O-rings.
Error on the side of underexposing rather than overexposing in underwater photography. Generally speaking, it’s easier to bring out colors from a darker photo with editing that one where all the color has been wiped out with too much light. While this is a good rule out of the water, it’s worth mentioning here, since underwater photographers often have very strong strobe lighting at their disposal. This better canon camera pictures and this what is the best panasonic digital camera for the money? should help with polaroid digital camera.
Don’t just consider the initial purchase price with your camera either. Buying a cheap Canon camera is one thing, but there’s an operation cost to be considered with any digital camera. Lots of megapixels may make for sharper resolution images, but they also take up more space on your memory cards and your computer.
Online retailers are a great source for cheap cameras. Many would be consumers realize that they can buy new products from big online retailers like Amazon and others. What some don’t realize, is that they can also buy used products as well. Used cameras will always be priced better than the latest models. A growing number of small camera retailers use the big online stores to sell their wares. What this means to the online shopper, is that looking at one web site is actually like browsing dozen of camera stores at the same time. It’s kind of like a shopping mall with nothing but camera stores.
One very underutilized source for cheap digital cameras is photography discussion forums. These forums are filled with camera enthusiasts of every imaginable level. From full time pros to digital camera newbies.
Have you ever wondered if buying a canon waterproof camera case and jumping into the ocean to snap a few pictures of that beautiful coral reef could destroy your camera? Well, you’d be right to wonder, because it certainly could. Water and digital electronics are a bad combination. At least for the electronics it’s a bad idea . . . the water will be fine 
If you still think trying it would be a good idea, there are a few simple precautions you can take to improve your odds for a good experience.
Take a few pictures while your in the pool. Preferably from varying distances, lighting, and angles. This should also give you a good idea of what your Canon camera is capable of under the water. There are different challenges to getting good underwater pictures. Generally speaking, the less water between you and your subject the better.
An additional precaution you can take is to get flooding insurance. The value of this varies greatly of course with the replacement cost of your camera. If it’s a simple $200 point and shoot, then it’s probably not worth it. A $1800 Canon SLR is of course a different story.
