I don't do selfies that much, for a couple of reasons; not having a flattering face is one of them, difficulty with clicking the shutter being the other, but this time i decided to study about lighting. The lighting setup in this shoot is much too simple (but the simpler, the better, yes?)
After a couple of tries, compared to using a very expensive diffuser, bought from Hanes (a sock; white, specifically), I decided to bounce the undiffused flash through the wall, towards the subject (me), and the reflector. The flash was full-CTO gelled, while no other light was used in the shoot. I used Canon 70-200 f/4 @ 70mm, F/11, 1/200, effectively cutting off any ambient light. The reflector managed to fill the shadows very nicely - to my surprise.
This was my first "studio" lighting setup, and of course, by "studio", I meant draping my window with a brown blanket, and use my mike boom as a holder for the reflector. When I saw the picture right out of the camera, I couldn't edit much anymore than what was there, so a little dodge and burn and that was it.
