LUTs are a great tool as a base for colour grading, and I often use them. But since I also got into movie editing a bit, one thing worries me in the Lightroom imposed order of operations. (Fixed order of transformations done to the base RAW image)
(correct me if I'm wrong - the profile is applied at the very beginning,and all other adjustments are built on top of that?)
So, many movie colour grading guides strongly advise against applying LUT first, but rather recommend doing colour correction first (all exposure related things, white balance.. ) and only after that start to creatively meddle with colours. It's because LUTs, especially 'creative' ones transform colours in a ways which can cause clipping a lot of information, which cannot be recovered later. And it seems there's no way to force Lightroom to process a profile afterwards (like you can do in Photoshop by the order of layers).
I started to think if it would be a good idea to do colour correction first, export to TIFF, and only start to do 'creative' colour grading and retouching on this re-imported image. But I wonder if it's worth the hassle, I would appreciate sharing some experiences related to work with LUT/Profiles. (Also apart from losing time I can lose some information from original RAW when exporting to TIFF, but again, is it important anyhow, after appropriate colour correction?)
