sailor,
depending on the limb lengths and strengths it may be helpful to adjust both hands. is there a shelf cut?
if you are shooting off the hand, then adjust both hands until you get the best balance. you are looking for;
even tiller
verticle handle
no handshock
and want the arrow knocked somewhere about 3/8"-1/2" (or there abouts) above where the arrow rests (on a shelf or bow hand)
flipping the bow upside down for photos causes it's own dramas. you need to both; draw it from the same spot on the string when upright and upside down, and also, push on the handle in the same place when upright and upside down. do it the right way up first and mark the string where you drew from and the handle where the pressure was (usually the pad at the bottom of the thumb or the webbing between the thumb and forefinger). you can use a small piece of electrical tape to mark the spots. when you flip it you need to be applying pressure to the same spots.
