Subject: Hair Light / Background Light / Fill Light ? Okay, so I just finished reading my book on portrait photography. It had about 40 pages on lighting techniques. Now, I know that 40 pages is really just a start, but it's about all I can absorb for now until I get some more experience. I also just purchased a 3-light studio strobe kit (with umbrellas and softboxes) from somebody on Ebay. All the basic techniques discussed in my book call for 4 lights: 1. Key light 2. Fill light 3. Hair light 4. Background Light Now, my questions are these? Is it possible to get by with just the 3 lights? Can I use a good reflector to act as either the fill light or hair light? Is the hair light really necessary? Could I use reflected light from the background light as the hair light? Or, should I just break down and start looking for a fourth light? If that's the case, does anybody know of a good, cheap 5600K strobe that would act as a slave (that would fire when the other strobes fire)? I want PROFESSIONAL looking results. Not just pretty good results. Thanks for any help you might give.
