Great point Ganesh. We have always been forward looking as photographers. But the advent of the selfie camera has literally flipped a photographers world from what's in front of us to what's behind us. And surprisingly we rely on our arms now to see. What a step change! If we ever have a photo category for "Best Selfie photographer" I would not be surprised to see the winner having 6ft arms
I guess nature photographers are still the old type who still rely on their eyes and... their index fingers!
