In that case you've overexposed the image - compression isn't going to turn red into white. It seems there is nothing in the "white" sky part but in reality it was smooth reddish glow With Canon sensors I had to really push the exposure as far to the right as possible because the shadows were so bad, but since moving to Sony I can pull 3-4 stops out of the shadows, no problem, so I've switched to protecting the highlights. The compression cuts off more and more data towards the hilights making ETTR a fail in any case. ![]() Not a problem if these areas are going to be squashed by gamma correction anyway, but if you drag the highlights into another region of the tone curve then yes you could cause issues with posterisation. Steps between values: 32 in highlight areas. With cRAW you need to do ETTL.ĭidn't realise you were talking about highlight recovery - detail in the highlights is not actually part of the definition of DR, hence my statement that lossy compression didn't affect DR. Now, good luck pulling anything back from there. There is nothing in the world to earn my trust in cRAW again. My first outing ever with A7 gave me that cr*p. I have zero trust in A7R2 working any different compared to A7R when it comes to using compressed RAW. Nikon D3/D700 are bad in hilight recovery but only if you really blow any channels. Now, I have used Nikon FX gear since D700 and almost all Canon FF up to 5Dsr. And the sky has posterization in both examples. It seems there is nothing in the "white" sky part but in reality it was smooth reddish glow. ![]() These are with zeroed settings in LR / linear curve. I have not used it since I got my R2 but here is an ETTR hilight recovery example using A7R. According to this video, the A7RII and the D810 are pretty much the same in highlight recovery:
