grab shot= meaning you walk around in nonchalant manner (something like mr bean )and see brids flying towards you and you raise your camera and rapid fire away.
can also mean
grab shot= you walk and see birds start flying towards you (then everything go into slomo mode-like in the movies), your hand grab the camera and in one motion sweep it up to eye level, your left hand on the zoom ring, and your right finger activating the shutter button while your legs get into a stable stance for shooting and than when the birds are in the right formation, you let 'rip' the five exposures. :sweatsm:
anyway, great stuff. looks like you knew they were coming. :thumbsup:
