Focussing in a digital age Pt II

The second part on focussing on the digital age turned out to be a let down for me. The techniques described are more for landscape and still life photographers. As a portrait photographer whose subject is constantly moving, I cannot do something like take 5 shots at different focal lengths and stitch an image back together in software. At least not for most of my portraits. i will take note of this if I have a commercial use for it though.
