A subject like that you wouldn't even see my hands move. Ask no questions, do not pass go, do not collect $200, go directly to the proper lens for the job. (A rectangular fish, of course.) Get down low, keep the horizon level and in the centre of the frame: can't go wring, instant classic.

(87 out of 100 photographers will disagree, and the a dozen other won't understand the question. but that's fine: they are wrong and I am right. This is a job for the big fish.)
