Ok, so I have what I think is a pretty good idea. Obviously on a camera you can only focus at one distance at a time. However, you can also only expose at one level at a time. This is based on the theory behind HDR photography. If you look at it like exposure bracketing, then you just set the middle focus point you want, & then the camera would snap shots with focus levels one step above & one step below. This isn't built into cameras (yet ), but you could do it with manual focus. Then in post-processing on the PC you would use custom software (like Photomatrix Pro & the merge to HDR option in Photoshop, but these are for HDR) to merge the different focus levels. It all checks out in theory, and it would give a perfectly clear image that would look really good. I don't know how to write software to automate the whole process, but tomorrow if I get time I will make a patchwork shot in Photoshop by mixing different parts of several images in different focuses. I will see how it works & post the shots here. What do you guys think of this?
