can anyone tell me why everytime I take a pic with the flash(stock on the body) My pictures are blue. i've tryed adjusting the xposure up and down but it only gets a drker blue or lighter blue, but still blue. I've adjusted apeture and shutter speeds as well. still blue though! The only way to use this flash and not get a blue tint is to hold my finger in front of the flash.<-I know it sounds dumb, but it did work. What am i missing?
