This project is another focus stacking experiment. I used the feature of my Nikon D850 camera to shoot a focus bracketing series. I shot a series with 30 pictures with a step of 3. I used the HeliconFocus software with the presets A/B/C to process the images. In my view, all presets result in similar results. I cannot find any kind of processing errors.
