They also had a very interesting section on working with HDR pictures (where you take the same picture with different exposures so you can create a "High Dynamic Range" picture by combining them).
I've been reading up on stuff like this Craig.
Very similar to what you describe is a multi-shot technique that helps out with the extremely narrow depth of field you get with macro shots. You take a number of identically framed shots of your subject, but change the focus slightly for each one. Using Adobe Camera Raw you select out only the sharp areas of each image before creating a composite that looks sharp from front to back. Real nifty.
I recently got Photoshop Elements 11, mainly for the improved version of the
Refine Edge feature (which I'm slowly getting to grips with). One of these days, I'll pony up for the full version of PS, but Elements is pretty good with RAW (it has version 7.1, the same as CS6, but with a few features missing). I also really like the Canon
Digital Photo Professional software that came with my EOS.
