I thought it might be possible in LibRaw, but I can't make sense of the documentation. Ps also uses ACR, but I assume that is run first as well, since Ps doesn't deal with RAW files at all. And the resize option is only on export, so I assume that is done last. I assume Lrc de-mosaics before doing other adjustments. But if you do super resolution, perhaps it too does what you are asking. Perhaps also Photoshop's Super Resolution as you start with the RAW in ACR and let it do its thing.īut be assured that if you start with Lightroom, the first thing it does is demosaicing. But I can only guess how this works internally. And once you commit to the crop, model and resize, it goes to work. When you load a RAW file, you get a preview, and the choice of the resizing size you want to do as well as possible cropping you wish to use. I am guessing that Gigapixel AI might do this, but I'm not sure. I suppose the only way this might be happening is where you use an application that does both demosaicing of the RAW and the resizing. So rather than taking the de-mosaiced image and then doing a nearest neighbor upscale, could I do that to the raw image first to create a pseudo quad Bayer raw, and then de-mosaic that? Or better still just use a de-mosaic algorithm that optimizes an upscaled output directly from the raw file (CR3 in my case).

But I think it would be advantageous to do both at the same time. The workflow I am using now does the de-mosaic in Lrc and the upscale in Ps. I'm wondering if there is a simple way to de-mosaic and upscale at the same time for super-resolution image stacking.
