From the mailbag:
Thanks for the blog series on ETTR and UniWB. I’m not sure, but I may have been among the earliest to describe the trivial way for UniWb with Canon: lens cap black or totally blown over-exposure. I was unable to easily find the date on your blog article.
You may or may not be aware that Magic Lantern (ML) implemented RAW histogram, leading to RAW blinkies, RAW preview, RAW review, auto-ETTR, and eventually to RAW video. With that feature, UniWB is a non-issue … totally unnecessary.
Really not meaning to “pat myself on the back”, but that came about due to my “Feature Request” for RawDigger-like capabilities in ML.
