Re Zerene DMap: it's my default for flowers and the like. In the case of the butcher's broom, the image done with the rail has much more haloing (look at the leaves at the top left), but since the stacking method was the same, the only possible explanations, it seems to me, would be camera movement or differences in the focus gap between images. My guess is that the major difference is the amount of camera movement. I would welcome any comment on these images as to which gives the best results. I had to rig up a cardboard dial to gradually change the focusing position. One problem with the lens focusing is that the total angle of rotation between front and back is quite small. Given that, I would say that for most purposes, focusing using the lens would be the best bet. I cannot see any real differences between the two. I fused the two final images from Zerene in Affinity. One problem with the rail is that because of the camera angle, as I racked forward and back, the image drifted up and down. I think these imperfections were probably my fault. One thing that is apparent is that the lens-focussed image has some imperfections in alignment in the nearer parts of the cone, but it would be hard to tell any differences in the further parts. In all cases, the Zerene Depth Map have the best results. The larger cladodes are about 2cm long.Īll the images were processed using Helicon Focus (three algorithms) and Zerene Stacker (two algorithms). Currently the plant in my garden is bearing red berries just over 1cm across. The second was a sprig of Butcher's Broom Ruscus aculeatus, a strange member of the Lily family in which the leaves are replaced by woody expanded stems called cladodes. It was positioned with the tip of the cone facing the camera. The first is a Pine cone, about 7cm top-to-bottom and 5cm across.
#Zerene focus stacker compared to helicon focus trial
I have been wondering which technique would be best for Focus Stacking, so I thought I would set up a trial with a couple of objects.
