Catherine,
Helicon Focus is a program offered by HeliconSoft that allows the user to increase dof in an image by taking a series of images of the same subject but at different focal planes and then loading them into the application where they are processed to create a composite image comprised of the in focus portions of the individual images. For instance, suppose I want to do a macro of a flower's center. Even if I set the f stop to 20, I probably won't be able to get the entire subject in focus. Plus, if there's much wind or low light I may not be able to get a clear exposure. With Helicon Focus, I'd pick a shutter speed that got me the shot I wanted but I'd take multiple exposures at different focal planes to capture everything I want in dof. I'd then load those images into Helicon Focus and create a composite image. It's a software solution to what would normally be a hardware problem. If you're interested in looking at there products the home page is WWW.heliconsoft.com.
In the image above I used nine or ten images, taken from a tripod over about a 30 second period. There was enough wind that I ended up with some artifacts (mostly blurred portions of the image) that I needed to clone out of the composite. Ideally, I think you'd use the software on images where there was no movement during the session. Although, since I don't know much about the software at this point, I'd be curious to see what happens if I had, say a bee, flying through the space. Would I get multiple bees in the final composite? I don't know.
Sorry I missed your question. I think you must have been entering it while I was responding to Catherine. So far, and I've only had it over last weekend, I'm very pleased with the Helicon Focus product. I'd say that the user interface is very intuitive and based on my limited experience with it, it works the way I would want.
I have no idea at this point as to how much control if offers. How does the basic algorithm work? Does the order of image processing affect the final result? How is brightness handled when it varies between images - say a cloud passes over? How are anomalies in the shot defined and addressed? - the bee example above. I think it will be a lot of fun trying to figure this stuff out.

Great comp and color! Love the detail in the center as well.

Pat, I tried Helicon Focus but I was not so bravo as you was. So now I prefer to take two o three shots exposing fore, centre, back and then merge them with the levels in PS.
Cheers.
Congratulations on the EP.
