Reminds me of the time my husband put a roll of film and a $20 bill in a film canister and then put it in the pocket of his swim shorts. The waves washed it out. My hope is that someday, somewhere, somebody will post the shots on the 'net along with his story of how he found it.
wow, what a neat photo. I like the composition, maybe the sun in the lens cap is too much, but then again, maybe not, it gives the feeling of a warm sun just on the horizon, good job
