+1 to Rodeo Joe's comment about lighting from bounced flash. One interesting technique--providing that the walls are relatively light and neutral--is to aim the flash diagonally backwards over one shoulder. This can produce a very appealing light, similar to having a high window in that location. It's similar to lighting used in some paintings.I don't do this with candids of kids--they move too fast for me to think about what walls are where--but I've used it with adults, and it's worked well. In general, I think a number of the postings in this thread overcomplicated matters for the OP. The fact is that in many indoor situations, simply bouncing an e-TTL flash--ideally with a bounce card--can produce excellent results with mininum fuss and bother. Are they studio-quality? Often not. Are they close enough that people looking at them as family photos won't notice any failings? Yes. I've noticed many times that when I say that I am dissatisfied with one of my candids, I'm the ONLY ONE who is concerned. Unless something is seriously wrong, most people look at family photos for the situation and the memory.
