Thanks for the thoughtful and well considered comments.

Since I use a motor driven dSLR most of the time, I usually have the photo in just a few seconds.

I always set up the foreground and background and fisherman's position before I ever take a photo.

I personally prefer to photograph fish destined to the Barbie which allows me more time for composition than C&R fish which are by necessity done very quickly.

I can knock out 3 or 4 frames in a couple of seconds on a C&R fish, but used the 15 seconds as a maximum example.
