Once, the idea of rotating my canvas when retouching was jarring to me. I knew it was something my peers were doing but I just couldn’t be bothered to try it myself.
After a few one on one lessons where I was “forced” to do it by David Neilands, I actually found a surprising improvement in not only the end result but also in identifying problems quicker with fewer revisions.
Rotating the canvas is actually a technique that was popularised by Pratik Naik of Solstice Retouch. The guy knows his stuff, he won retoucher of the year last year!
