Please don't send me questions how to process Vuescan-DNG in Lightroom, Aperture or other Raw-editing applications. Sascha Steinhoff, the author of the Vuescan Bible, goes as far as to put this on the english home page of his web site: Using a VueScan-generated DNG outside of VueScan though is not really recommended. ![]() The downside is the extra storage, but unless its tons of images it shouldnt be that bad (should it ? )ĭNG will also retain the IR channel if you set up VueScan to include it. that way you have easier access to a 'RAW' file should you want to play with it. then when importing into LR5 id stack the 2 together. I think because of the darkness thing Id be tempted to export the processed TIFF as well as the RAW TIFF (or DNG). I'm probably just missing something in the VueScan software… I haven't been able to figure out how to re-scan and save all the files as standard TIFFs in one go. But then I have to click the "Save" button for each image to save it as a standard TIFF file. It goes like this: I have to re-open ("re-scan") the images from the Raw files, which I can do as a batch process. Unfortunately, so far I've only been able to do semi-batch processing in VueScan. This is what I would like to do if I can find a way to do true batch processing. I think the best thing is probably to scan everything as a Raw TIFF and then convert all the images to standard TIFF files for editing LR. My understanding is that these RGBi files can be opened in other applications but the infrared channel is ignored (same thing if the Raw files are saved as DNG instead of TIFF, I think). #VUESCAN BATCH SCAN FULL#A full Raw VueScan file is a 64-bit TIFF (an "RGBi" file) which has three 16-bit color channels (48 bits total) and one infrared channel, which is what the "i" stands for. The exception (I think) is the infrared channel, which can't be wrapped in a DNG because there isn't anywhere to put it within the DNG standard. TIFF is the standard VueScan Raw format but most of the information can also be wrapped up in a DNG. They appear dark in other applications because they have a gamma of 1.0 whereas exported TIFF files have a gamma of 2.2. It's just an extra step that I'd like to avoid if it's not needed.īased on what I've read on the internet, the Raw ViewScan files are really only intended to be re-edited within VueScan itself. I can fix this problem in LR by adjusting exposure, but I'm not sure if it's better to export to a normal TIFF first, which I can do, and which appears as the correct brightness/exposure. I should have given a little bit more information up front: The VueScan "Raw" files can be either TIFFs or DNGs, and I'm able to open the Raw TIFFs in Lightroom. #VUESCAN BATCH SCAN SOFTWARE#I'm still waiting for my new scanner to come in (delayed due to the snowstorm) so I'm just testing out the software with my old Epson 2480. Hi again Ian! Yes, I have Lightroom 5 and I also have VueScan Professional. if you dont have LR then you can download the trial. ĭo you have LR at the moment? if so you can just try to impprt a few of the RAW scans to see what happens. It seems the Vuescan RAW is DNG so it should be fine. #VUESCAN BATCH SCAN MANUAL#I'm still reading the VueScan user manual to try to figure this stuff out, but in the meantime advice from experienced VueScan users would be very appreciated on how best to use VueScan and Lightroom together.Ī quick google of Vuescan Raw in Lightroom says yes. What I am definitely going to do is process the scanned images in Lightroom 5… So my biggest question is: Is it okay to use the Raw images for these edits? Or should I export to standard TIFF or JPG files first? ![]() In reality I probably never re-process them in VueScan, but it makes me feel good to save the Raw files just in case. I've been scanning the slides as VueScan "Raw" files so that I can re-process them in the future with VueScan without rescanning the slides. ![]() Can anyone suggest a good workflow for using VueScan together with Lightroom? I'm a bit confused about the VueScan "Raw" format and whether or not it plays nicely with Lightroom. ![]()
