Hi, I'm a beginner. I have a nikon d50, and I just had a question about how I can improve the way my subjects turn out in my photos. I looked through some photos of my friends' dslrs and their lighting on their subjects truly lights up their faces (for indoor photos). My camera doesn't produce such results. I was wondering is this cause my camera's built in flash isn't as well equipped? Would I need to buy something extra to make this happen? Thank you for your help!
