The guy is showing the right way of using a mobile phone – stay still, which I should have done likewise.
Weeks ago knocking off from work, I was on the phone while on the move. I was very watchful about this coz there had been accidents of such people losing their life to moving vehicles. But I was too certain. No sooner had I finished it and slid it in my pocket then I landed my foot on the wrong step down a flight of stairs. My foot was later diagnosed to have a ligament completely torn apart and the other two damaged. The talar dome, a cartilage between the foot and the lower leg, was bruised. Which if broken can be a real headache. The specialist said that it was the worst grade three high sprain causing an unstable ankle and hinted that I was very close to being lame for life. The complete recovery could take six months.
The thought of limping around on crutches without a camera around anymore was terrifying. I almost lost my hobby to a silly sprain and the phone call.
So, photographer folks, you know how and when to and not to use the cellphone. Be safe.
