I'm sure this topic has been done to death here and elsewhere, but I'm obviously dumb because I don't see the answer to my specific needs:
For personal reasons I'm frantically spending all my time scanning and processing a life time collection of slides going as far back as 60 years. LR is the obvious choice of Digital Asset Manager, but I cannot expect my children to have or even want to have LR to hand. The question of the format of the images that I leave for them is key. I'm sufficiently persuaded by Adobe's argument to choose DNG as output, along with jpeg for ease of use.
The 2 chief weaknesses of jpeg, in my view, are (1) that even when I select an output of 1920 pixels on the long edge, at 96 DPI (I'm not catering for Apple or Android devices), the jpegs might contain as little as 25% of the available pixels I've scanned from my slides. (I'm using a Nikon LS V ED, together with Vuescan). (2) the quality will be quickly corrupted if the images are viewed and saved multiple times.
So, DNG is important. It also allows them to properly re-edit the images if my children have the skills and software to do it. For ease of use the DNG files must be directly browse-able in Windows, especially as the Adobe DNG codec frequently referred to on the Internet appears to have been effectively hidden from me by Adobe. However, when I tried to view the DNG files exported from LR, with no embedded jpeg (I already have a big jpeg as a standalone file), using Win 10 Photos app. the results are unusable. Win 10 Photos completely misunderstands the image size properties. If I embed a jpeg then the image is viewable in Photos - but I'm only seeing the jpeg and not the full-fat file, so there's no point in exporting the DNG file.
If I switch to using a much more functionally capable image viewer - like IrfanView - the DNG files are browse-able with or without an embedded jpeg. But without the jpeg IrfanView presents the image as it is BEFORE adjustments have been applied in LR - and that's of no value to me or those that look at these old, colour-faded, dust-ridden slides. With a jpeg embedded, IrfanView shows me only the jpeg - again making the DNG file irrelevant.
So, how can DNG files be viewed correctly, and as LR intended, in Win 10?
