Ok my camera works fine in natural light situations but when it comes to using the flash, the pictures always come out really grainy and badly lit. What could I be doing wrong? The flash I use is a Quantaray QB-350A, if that means anything to anyone. It's an attachable flash and one in which the angle can be adjusted and theres this little switch at the botton with 3 squares-one blue, yellow and then a white and I really don't know what they are for but I am wondering if that's got something to do with it. In any case I am sick of my night time pictures coming out so shitty so any advice will be gladly accepted. Thanks!
