Well my friend is trying to build up her modelling portfolio and I'm trying to build up my photography portfolio.. so I will be taking photographs of her on Sunday. I told her that around 4-5pm would be the best time because the sun will be setting. Also, out of the lenses that I have, which one(s) would be ideal for shooting portrait photography. I will want shots of her face/head and then some shots of her full body. Lenses: Canon 70-200 f/4L Tamron 28-75 f/2.8 Canon 10-22 f/3.4-4.5 Canon 50 f/1.8 All on a Canon 30D SLR camera. Also, I'm sure most of you will recommend me shooting with the 70-200 f/4L lens. Should I shoot at wide open or no? What if I chose to shoot some shots with the Tamron lens.. should I shoot wide open or no? I know for the headshots I should probably shoot at wide open to get good bokeh for the background. But as for her.. if she's leaning or sitting on a railing or whatever, should I have the background in focus or blur it out? I will be shooting with a 430ex speedlite flash and I have a couple of diffusers but I will probably be using my Gary Fong Light Sphere II with Inverted Dome pointed directly at her (yeah yeah I know you all hate gary fong). Any other tips for doing an outdoor photoshoot?
