Like you, I've been enjoying the pictures Michael has been posting with his NEX-7 rolling review, and they set me wondering in general terms about his current practice.
I'm sure much depends on the particular situation, and varies greatly day to day, but the kind of questions I have are about how many photos taken versus how many photos kept, how many photos taken of a particular subject versus how many photos kept? Just a general impression of how hard a scene is being worked to make a satisfactory picture.
(I also wondered about how using NEX-7 might influence picture taking, but I assume that after so many decades it's more a matter of each new camera fitting into a well-grooved approach rather than fitting the approach to the new camera.)
