![]() Usually this is a raw scan file you created with VueScan or a file from a digital camera.ĭisk files can be scanned just like a normal scanner. Specify the name of an image file that VueScan will read when you set the “Source” option to “File”. ![]() The name can be a TIFF file from a previous scan, a JPEG or TIFF file from a digital camera, or a raw file from a digital camera. If you set this option to “File”, then you’ll be able to enter a file name in the Input | Files option. This option lets you read that raw file as though you were scanning it. On the Output tab, VueScan provides a special option to save the raw output of a regular scan to a file. If you’ve got more than one scanner on your system, this lets you specify which scanner you want to use.Ī special “scan from” source is from a disk file. Professional Option: This option is always displayed. Choose from “Scan to file”, “Copy to printer”, “Profile scanner”, “Profile printer”, “Profile film” and “Make IT8 target”.Ī brief reminder of how to do each task is displayed in the lower left corner of the window. ![]() Use this option to indicate the task you’re performing. Use this to indicate whether you want to see a simplified subset of the options (‘Basic options’), or all the commonly-used options (‘Standard options’) or all the more advanced options (‘Professional options’) īasic Option: This option is always displayed. I think this is very useful, because the batch scan can take a long time, and it's nice to be able to go away, and not have to be present to set the focus point on each frame.This tab contains the options that control the inputs to VueScan from scanners, raw scan files and digital camera files. This tells me that Vuescan is doing the right thing: it is storing the different focus point locations I specified for different frames, and using them when doing the batch scan. Then I did a "Scan".įrame#1 came out in focus the right side of frame#2 (that was elevated) was also in focus, while the left side was out of focus. I went to frame#2 and set the focus point to lie on the right side (where the film was elevated above the normal level) in frame#1, I set the focus point to the left side. I set "BatchScan | On" and "AutoFocus | Scan". In the film holder, I put a plain slide in frame#1, and this "split level" test slide in frame#2. I fabricated a test slide that's split, with two different "heights": on the left side, the film is in the same plane (same height) as a normal slide, and on the right side, it is raised the thickness of two slide mounts. I decided to do a test to see if Vuescan does indeed allow one to set different focus points, for the different slides in a batch (a load of 5 slides in the Nikon LS-8000 mounted-slide film holder), and use those distinct focus points when doing a batch scan. I wonder if others have dealt with this problem, and if so, how. ![]() But it appears to me that it doesn't actually use the 5 distinct focus points 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 best (and easiest) to achieve good focus. I would like to scan batches of 5 mounted 35mm slides in my Nikon LS-8000, using Vuescan. ![]()
