I my search foo sucks so couldn't find much. I am going on a canoe trip next summer and don't have a lot of money so am starting my research now. I would like to take my D40 with me. However, I am not sure what to do waterproofing or how I could protect my camera while in the canoe, might just keep it in bag. I want to take it because it is not often I get in a situation to take potentially awesome pictures. What are some things I can do for safe guarding my camera?
