I am coming for help. I've just start product photography recently cus these days I started to run a online store. I got a lot of question and I think most of you here are more experienced than me, so I come here to get some advice. Here it is, I need to photograph some bright colored items like kid's toys and clothes, don't know how many watt of the lighting I need? Does daylight bulbs fit? I use Nikon D4. Plus, I've came across a lighting kit with two 20"L x 28"W soft boxes, is this size big enough?
