Hello. This is my first time to this site...looks great. I am a beginning photographer and am trying to learn portrait photog. I have been practicing for free on a few models. However, tomorrow, a customer who has seen my work and was pleased is paying me to do a photoshoot of her two sons: 13 and 17. I have not practicted on any guys yet. Any ideas for posing? I am really just not sure and google has not given me what I needed. I would appreciate any advice you have. Also, if you want to post samples here, that would be even better. I am extremely nervous... Thank you.
