I'm new to the forums as well as a new user of DSLR cameras. I just purchased the Nikon D5100 with the standard lens and have been trying to take effective indoor portraits without flash. I use A mode and have tweaked the focal point to be spot. I'd like to know what I can do indoors to get the natural look given what I have available at the moment or do I just have to use flash (currently set to ISO 500 and flash on f/5.6 55m)? Thanks everyone!
