Focus Stacking Experiments

Surprisingly few fungi in Hayley Wood compared with others visited but we found enough to take a variety of focus-bracketed images. The fly is a stack from just 5 images (F16) before it took off!. The fungi used larger stacks with apertures of F2-F8 (15 hand-held images using Fuji X100V plus Raynox 150). 
Following a very comprehensive talk by Duncan on various software for focus stacking, I returned to the images of the Shining Ink Cap and processed one stack with Zerene Stacker using PMax (my usual method) and DMap techniques and also Photoshop. Certainly for this image, DMap gave the sharpest image with least aberration, followed by Photoshop while the PMax technique produced a strong halo.
