topleftpixel forums :: View topic – tips for handheld shooting: Most of the information here is very helpful, but I need to clarify the breathing aspect. The technique that should be used to stabilize your body is to breathe out 10-15% of your tidal volume and then pause. The reasoning is two-fold. One, your body has a natural rise and fall with each inhale and exhale. By the time you’ve exhaled 50% of your tidal volume, your chest is no longer moving from dorsal to ventral and most of the motion is rostral to caudal. If you only exhale a small amount, your body would not have moved dramatically from the original position when aiming had occured. Two, and you can try this at home, if you are exhaling and then pause, your heart will skip a beat. This technique will stabilize your body as much as possible.
