[QUOTE="WayneF, post: 225047, member: 12496"] Adobe "As Shot" or any "Auto" are rarely your best White Balance choices. As Shot WB tries to figure out what WB was set in the camera, it s NOT about what it should have been. Camera White Balance result is already in JPG files, but WB is not applied to Raw files, and its numeric value is not in the Exif either. There are proprietary numbers in the Exif, and "As Shot" is merely Adobes best guess what they mean (different cameras, etc). Again, it just tries to figure out what was set in the camera, and is not about what it should have been. There are inaccuracies, and As Shot is never the best value, we need to actually set WB in Raw files. As Shot just means you have not done it yet. The beauty is we can do this after we see it, to know what it needs and how it comes out. Auto WB is just a try to look at the pixels we got and try to guess what they ought to have been. Auto is not about the light in the scene, it does not know the light at the scene. Two better tries are: 1. If you KNOW you used flash, why not set flash WB to try to help the dumb automation? Or if you know it was shady daylight or cloudy, why not set those? Help it out. Good starting points. Looking at the picture later gives human brains strong clues, but it doesn't help the dumb automation much. 2. Standard White Card practices are near magic to actually tweak it right. The Camera profiles offer choices like Standard, Neutral, Vivid, etc. They are supposed to manipulate the colors. These are not about White Balance, which is a different concern. [/QUOTE]
