My wife recently volunteered me to take candids at her upcoming 30th h.s. class reunion.

I have a pentax K7 with kit lenses. (My fixed 50mm 1.4 won't autofocus on the K7.)

I also have a AF-360 FGZ hotshoe flash.

Since I won't have a chance to reshoot, what are some tips to get quality photos that are fun to view later?
