My BS detector is going off (a bit).
Agree. Mine is going off at full volume. The guy in the video keeps repeating, like the voice of God, "Are adjustment layers above a raw smart object non-destructive?
NO!" Finally, at 3:08, he inserts the crucial qualifier: "All adjustment layers, all smart objects, are done at the pixel level
when the image is flattened."
Well, duh! If you flatten the image, then of course the edits are destructive. But when you open a raw file from ACR into CS6 as a smart object, and when you use adjustment layers and make other non-destructive edits (such as cloning on blank layers),
that process is non-destructive. After editing, if you want to save the image as a jpeg or tiff, fine. Save it that way. But
don't flatten the PSD file. Save it with all layers intact, so you can return and make further edits later. If for some reason you want to return to the original raw file, it's right there in the smart object, undisturbed by any of your non-destructive edits.
The guy in the video is a pedantic BS artist. I don't think he is offering any useful advice. I certainly wouldn't pay $154 for his "Full video course 5 Years in the Making!" I'd rather shave my head with a cheese grater than listen to that.
