After looking at the video I have a question about my photographing technique. I generally always keep my forefinger (of right hand) on the shutter button. It always touches the button and when I am about to take the photo I press it (once, since I generally use back button focus). But the video show that the forefinger is kept far away and at the moment of the capture it looks like it "hits" the shutter button rather than gently press it. I hope my technique is correct and not the one shown in the video. Yeah, me from India too and a thich swede type or velvet bindi will do the trick as well.You technique is right. Shutter release button should be squeezed, not to be hit , to minimize vibration. Just look at the M series camera from Leica. A dish is built around the shutter release for the trigger finger to be rest on for squeezing, not hitting.
