how many is to many in a row?
I usually take 3 or 4 shots of each pose, maybe double that or triple that if I use different angles but I dont do that to often. Then were off to the next location and/or pose.

I range from 150 to 250 pictures in an hour session. it may seem like a lot but they are in sets of 3 or 4 of almost the same thing, just slight differences in facial expressions, usually there is 1 they love and the rest are forgettable which is why I do it the way it is, want to make sure I get that one they love.
