Have any of you experimented with focus stacking when shooting macro. I tried it for the first time this weekend. The idea is to use multiple shots with different focus and a relatively large aperture, let's say f/8 where the lens is sharp. At smaller apertures diffraction limits the sharpness. Then these shots, it may be as many as you need, I often ended up with 15+ shots, are combined to 1 image. There are several software solutions for this. I used Helicon focus. This is one example. As you can see everything I wanted is in focus. I used my Canon 7D and the Canon 100mm f/2.8L Macro lens.
