i lost most of my right hand in an accident at work back in 1982 which basically left me with most of my thumb and not much else
being naturally right handed even after all this time make some jobs still difficult ie using a hammer for instance
swinging a hammer with my left hand just never seems right
from a photography point of view i still do ok and am still able to press the shutter with my right thumb but shutter speeds have to be fairly high or i can grip the camera with my left hand from over the top and fire the shutter that way
there's always ways around things
