I need to shoot some pictures of a person holding a guitar for the cover of some DVDs. I'm in a 11x11 room, with a blue screen (I normally shoot video in this room) I have these two halogen shoplights that I aim directly up at the white ceiling and this is fine for my video shoots since the room is small. However, I've discovered that simply aiming the two lights up at the ceiling doesn't work for photography. I'm just using a regular Canon Powershot to take the pictures. I know it's not the best camera for the job but it will do the job and I think if I get really good lighting, the picture should come out fine. Can someone here tell me 1) Can I utilize these halogen clip on shop lights? 2) What additional lights I need to buy (not expensive photography lighting though) 3) Where to position the lights, etc..
