I have spent the past several days exploring focus stacking, capturing short videos, typically about a second long, with my Panasonic FZ330 bridge camera and Canon 500D close-up lens, and processing them in Helicon Focus. This is a new technique for me and I think it may change how I do some of my botanical photography. That being the case I should probably add something to my Journey thread describing what I have learnt, but that could be rather long and dry, and may be of only limited interest. Instead, at least for now, I thought I would simply post some examples. Because of the geometry involved I doubt whether any of these could have been captured with a single shot.
I did not note the exact numbers, but each of these images is a stack of somewhere between 10 and 40 or so 4K video frames. The videos were captured hand-held using Panasonic's Post focus technology, which captured between around 40 and 160 frames for each capture, varying the focus during the capture.
It was breezy. Not only were the subjects moving, but in one case (#4) parts of the subject were moving a lot relative to other parts of the subject, with lesser relative movements for some of the other subjects. The software handles "rigid" subject movement quite well, but relative movement of different parts of the subject causes artefacts. I therefore did a bit of retouching in Helicon Focus for several of these before passing them on to Silkypix. After Silkypix, the first three had minor adjustments in Lightroom. After Lightroom, the first one had its background smoothed in Nik Dfine.
