Shutter Pressing and camera motion blur

When pressing the shutter, do not use your finger tip to stab the shutter release. See link below for more detail:

How could I have missed this for using a convention DSL for so many year.

Another tips for tackling camera motion blur is to shoot 3 or more and pick the sharpest one. Camera motion blur is a probability thing. As shutter speed goes low, the chance of getting camera motion blue is higher. To overcome this, we increase the number of shots we take and hence increase the chance we got a clean shot.
