austrokiwi Pillar of the Community 2087 Posts	Posted 05/28/2016 12:32 am I was in a hurry to create some large pictures of some coins. I set the stack increment wrongly. It was at 0.045mm when I could have got away with 0.490mm comfortable. Magnification was about 1.6X sensor full frame. I get these interesting(not) artifacts at the 100% zoom level. I have never seen this before; I did have very frustrating issues with Helicon focus. The night before I had upgraded, and when I turned the computer on last night the program had reverted to demo mode. It took some frustrated emails to Helicon before I got a link to down load Helicon again. Then I did the problem stack(47 photos): Settings for the stack depth map, 100% resolution, radius 8, smoothing 4 Report this Post to the Staff

Edit: Ok it was more than one issue( shows how flustered I was over the Soft ware issue...my brain had switched off!) I was using axial lighting so that was the majority of the problem. The beam-splitter was blurring the fine detail then add in IBIS and you can see the result. I repeated the stack going a step further than just removing the axial lighting smoothing to 1 and radius to 1 plus silent shutter (fully electronic shutter) to Use the fully electronic shutter I had to adjust the lighting and exposure so the shutter speed was not a a factor of 50hz( power frequency here) this ensures no light and dark banding in the image: Here is a crop showing much better results( lens was Staeble-Magnon 105/5.6 @ 5.6: I am feeling like an idiot as now I have to repeat last nights work. Here is the coin I used to sort the issue out Edited by austrokiwi 05/28/2016 01:39 am Report this Post to the Staff

Thanks I use a black background for all my shots and evey so often when editing I miss dust flecks which sometimes aren't removed with the rest of the background. I am much more careful with the final images.the one here was just to show the coin Report this Post to the Staff
