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.

Camera or Image
I think this is the most important reading in Kenrockwell's website.
Your Camera Doesn't Matter
I don't think he mean camera and lens is unimportant. It is the time and energy spent on chasing equipment should not out-weight those spent on making photographs.

Color Histogram
Have learn a lesson today about histogram. If you are shooting picture of flower which drive one of the color channel over, it should be considered as normal and do not try to reduce exposure to bring the over channel back in range. But doing so, it will bring to other two channels to seriously underexposure. And detail information of the color which drive the over channel will be lost.
The lesson is although you need to prevent overepxosure in digital shooting, you need to excerse this in context.
The following photographs and corresponding histogram is used to illustrate my point here:
1. The photograph I have taken with -1 EV exposure compensation. Note that the red channel is not overexposed.
2. This one is obtained with +0.5EV from RAW to JPG conversion. Note the red channel starts to have overexposure show in the histogram.
3. The final one is obtained with +1 EV from RAW to JPG conversion. Note the red channel is shown clearly with overexposure from the histogram. But at the same time the information contained in both green and blue channel increased considerably.
