I don't really have any portraits in my portfolio so I volunteered my mom to be a model. I'm mainly going to focus on shoulder up portraits and not full body. I guess you could say similar to senior portraits. My lenses are: 28-105mm f4-5.6, 17-40mm f4, and a 75-300mm f4-5.6. Of the 3 I have I was thinking of getting a distance away from her and using the 75-300mm because I think it has the most pleasant bokeh of the 3, but I don't know if that would be the right one to use or not. I don't want to purchase a good portrait specific lens just yet. For lighting I have nothing. I can try and emulate a studio condition I guess with a mix of sheets and bright lights, but that might be pushing it. All I have right now is my built in flash. I will be using Ilford Delta 100 Professional Black and White Film. If I use color film what ISO would be best for portraits? Any suggestions on the lens, lighting, pose, and anything else are appreciated.
