Once your hummers get used to your feeders you will be able to hand feed them. The best thing to do is to find a position that is comfortable for you. Also, if you will have someone else there to photograph your success, they should find a comfortable position. Naturally you will have to keep your movements smooth to keep from startling your hummers. Since the use of a flash will startle them you might want to consider laying a piece of foil paper on you lap to reflect light on to your subject. Your photographer should not try to follow the subject with the camera, but instead pre-focus on the general area of the feeder as the subject will come to that spot. Have fun!
