Nice fish Tom.....
I've had the same problem before with the disposible camera at dusk.
You might have looked already, but if not, take a good look at your negatives, if you can see even a hint of the picture, you might be able to get those picture developed. I've got a couple pictures of
the kids with nice fish that I wouldn't have if I didn't take the
negative back. They can adjust the sensitivity on there systems and
print pictures that otherwise would be passed up on your origional drop off.
Digital camera would be an awesome stocking stuffer and maybe a scale ta boot... :-)

Good luck
Don
