And, as has been stated time and time again: you may not get a huge benefit from 4K in your home, depending on viewing distance and screen size. There are some other factors, however, that make ‘Ultra HD’ technology desirable, regardless of clarity so crisp you can’t even tell how crisp it really is. These factors are the other important goals defined in the ITU-R’s (aptly dubbed) Rec. 2020 spec for 4K/UHD.

Ever asked yourself, “What in the f#$% is a LUT?!” Or what a LUT’s relationship is with color space? Or what a color space is? If “yes,” not to worry — these concepts can be fairly confusing. Fortunately, engineering can and will work for you as an artist, so long as your understanding of it covers the fundamentals. And even if you answered “no” to all the above, you should still check out some of outstanding basic-breakdowns of these concepts below — including how to convert CinemaDNG footage into the Academy Color Encoding Spec color space (ACES) in Davinci Resolve, plus how to use that very program to generate dailies (like a boss).
