Manual focus stacking
If too much movement occurs between the individual shots for focus stacking, the software is often overwhelmed with processing the data. This happens often when taking handheld photos in nature. A single image taken with high magnification usually has too little depth of field to deliver a satisfactory result, so that only manual stacking can help.
In such a case, only manual intervention helps. To do this, the recipient image is selected into which the individual "snippets" of the other photos are inserted. Most of the time, this is the image with the focus at the back. Then the sharp areas of the photos are gradually cut out from back to front and inserted into the recipient image and brought into position with scaling and rotating. The overlapping areas are searched for at the edges and blended with the eraser and / or copier stamp tool. Ideally, the transitions are no longer visible and the stack cannot be recognized as such.
