I on the other hand am not a portrait/family photographer but if I were I would want more in my bag. I would personally feel lost without my basic kit (12-24, 24-70 an 70-200) and a couple of small flashes w/stands to use off-camera. I would also have a second body for back-up and and possibly a small location lighting kit like the Elinchrome Ranger Quadra for some locations. For you it will depend upon how/where you like to shoot. Just remember–more gear will not make you a better photographer. Your vision is the most important thing.

In regards to post-processing–it depends upon what I am shooting and for who. For most of my stock shoots I typically work up a larger number of files since I submit a significant number to my stock agency and like to add as many as possible to my own archives. For assignments when I am under tight deadlines or shoots specifically scheduled to create new work for my portfolio I work up fewer images. Especially if the portfolio images require a ton of post-processing. Time spent on post also varies. It can be as little as a few hours for some shoots or days as in the case of my recent shoot in Hawaii.
