Joan and I updated her
business portrait from a few years ago.
She brought along 2 outfits.
We photographed her in both outfits, in different poses, and she chose her favorite image which I then retouched for her.
The digital world has made this so much easier!
What I do is to take maybe 12 pictures, then upload them onto the laptop, and the client is able to decide whether more pictures are wanted in another outfit or in another pose, and so we proceed until the final choice is decided upon.
It works well.
