My camera's flash is partially blocked by the underwater housing. On night dives this is apparent because part of the photo is black from the flash being blocked. I know some underwater housings solve this by having a tiny flash diffuser that attaches to the housing (sometimes the housing includes the diffuser). Is there one on the market for this camera? I'd hate to have to waste money on an external flash to solve this problem. A better question is, why didn't this camera include one? This problem occurs with every photo taken on a night dive with the internal flash. Perhaps, Sealife should have tested the housing on a night dive before marketing it.
