I finally got my d200! While reading the manual getting the feel of the camera, I've been attempting to take some test shots of my kids. Problem is they blinked with EVERY SINGLE picture! I took maybe 40 pictures and every single one they have funny eyes. They keep blinking right when I snap the picture when the flash (on camera) goes off. They never blinked when I had my d50. Anything I can do about it?
