This is my first post here! Since updating to Lightroom Classic 10, when I click into an image, the white balance initially appears as it should be but then somehow appears a notch or two cooler a second later. The white balance doesn't actually physically change, so it looks right once the images are exported but it's highly annoying during the actual edit. Can anyone please help?!
Bug, How to, Mac, Presets or profiles, Problem or error
The initial view you are seeing is from the Embedded JPG image that is in every RAW file. That JPG has whatever camera settings you had set and the WB is what the Camera determins as correct at the time the Camera Processed the JPG from the RAW data. The second view you are seein is LrC Processing the actual RAW data and then building a Preview of that file and showing you that preview.
Whether it is a Bug or the newer processing system in LrC V10 no older previews are carried over from the older LrC V9 catalog file to the V10 Catalog (Even If they are Copied over and ot the name of the Previews folder has change to read V10). LrC V10 will build all new previews for each file viewed in either the Grid View or the Loupe view and Especially if you go into the Develop module.
