![]() This is probably more of a Vuescan question, than a general scanning or Nikon one. I wonder if others have dealt with this problem, and if so, how. But it appears to me that it doesn't actually retain the 5 distinct focus points that I set for the 5 slides), but rather just uses the first one. I thought perhaps it would work to batch preview the slides, then manually set the focus point for each one, and then batch scan. This seems to give good results, but does not allow batch scanning (the user must manually interact with Vuescan between each slide) - and this scanner is SLOW. Then scan the image with "Auto focus" set to "Scan" so that focus is done at the individually defined focus point, just before the scan. On each one, first do a preview, and then manually set (by moving the focus "cross hair" icon) the focus point to a spot that is not too near the center of edge of the slide, typical of the most interesting part of the image, and with some texture upon which to focus (such as an edge between very different brightnesses). The way to get the best result seems to be to step through the five slides individually. This would be a decent solution, except for times when, for a particular slide, the focus point lies on a part of the image with no edges or texture for the focus algorithm to use. ![]() As I understand it, Vuescan will have the scanner focus each slide at the specified X/Y focus point, before scanning it. Then (in the "Input" tab) set "Auto focus" to "Scan", and "Batch scan" to "All". The simplest thing is to set the focus point X/Y midway between an edge and the center of the transparency, to "split the difference" on a "cupped" slide. ![]() I am confused about how to achieve good focus, while still being able to batch scan. I am scanning mounted 35mm slides (using the 5-slide film carrier) in my Nikon LS-8000, using Vuescan. ![]()
