  1. Totally agree, but I used that as an example of how people might perceive the idea of optimal exposure. The best possible SNR doesn't care about people's preferences. It's an absolute with the only limitation of what highlights are allowed to be blown.
  2. Optimal exposure is fine and I understand why and how this term is used. However, (isn't there always an however?) full exposure IMO better reflects what you need to do to maximize SNR. Optimal exposure may be taken by some people to mean "Do not fully expose as the resulting brightness might by more than what you want your final image to look like." The term full wouldn't leave that mental wiggle room/ambiguity.
  3. How about something like: "Full exposure results in the best SNR (signal-to-noise ratio); as exposure is lowered, the SNR gets worse."? SNR is what really counts and "full exposure" sounds, in my opinion, better and is less provokative than e.g. ETTR, although it comes down to the same thing. This statement also includes both the absolute best possible case and what happens when you lower exposure. "Underexposure" in this context means "less-than-full exposure". Any constructive comments?
  4. Realized that I was misreading the Nikon color codes for the Yes and No choices: Yes in a black field and No with OK in a yellow field means No; Yes with OK in an orange field and No in a black field means Yes. Confusing to say the least.
  5. Playback Menu, Delete, All, asks "All images will be deleted. OK?" When I answer Yes, it doens't delete, when I anser No, it deletes.Setup Menu, Format memory card, asks "All images on memory card will be deleted. OK?" When I answer Yes, it doesn't format, when I answer No, itformats.Has anyone else had this experience and if so, did you find out what the solution was, other than just live with this? My camera seems to work fine otherwise.
  6. The Adobe Support Community thread this basterdized quote was taken from can be found here: https://community.adobe.com/t5/camera-raw-bugs/p-denoise-ai-and-pentax-k3-mkiii-dng-files-not-working/idi-p/13769456#comments Seems to me you did the right thing and showed that ISO invariance is a myth. Good for you and good for all of us.
  7. Don't go back into insult and superiority modes please. Nikon decides how much exposure headroom is used. I can't do ETTR on the spot because my Z50 doesn't tell me what the maximum values are in the R, G and B sensors. And you can thank Adobe ACR Auto mode for royally blowing out the hightlights.
  8. When I use 16-bit and use ACR Auto settings, I blow out the reds in many areas and in my PSE edition it results in the green overlay after using haze removal and nothing else. So, blame ACR Auto.
