I just started the journey to become a baby portrait photographer. I have an alienbee b800 light with a large octabox and that's it for lighting. (A little ambient light from windows in my home.) I keep getting shadows on subject's face when the light is a few feet away & a bit to the right. Is this the proper set up? SHould I have the light in front of the subject instead of the side? I don't have any other lighting/reflectors. Is there any way to fix the shadowing problem without getting any other equipment? Thanks so much!
