My first "commission"...though I did not get paid for it. My friend Joan needed photos her daughter Jessica could use for her senior picture, and I offered to help purely for the experience. I found out that taking portraits with two people is not twice as hard, it's quadruple! Still, it was a fun shoot and I was able to use the studio's strobe lights.
Jessica was especially helpful in that she had ideas for poses, such as the floor shots and the ones looking down from a step ladder.
