  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.
  9. I have many sunset images taken over about 15 minutes and they all have this green overlay after haze removal in varying degrees. I can take other images, for instance seascapes, blow out the reds on purpose and get a similar same effect, though less pronounced. So to me it looks like a combination of very contrasty images with blown out reds and a peculiar behavior of PSE, possibly unique to the 2021 edition.
  10. Totally agree with that. My ACR Auto setting makes the overall image look good, but blows out the reds in many areas. When I reduce "Exposure" in ACR to the point where nothing is clipped and then use Curves to increase the brightness to where I want it, I can use Haze Removal without the green overlay. Problems solved. Why PSE shows this overlay and why in 16-bit and not in 8-bit? Who knows, but to me it looks like the OOG warning feature wasn't totally removed from PSE. Thanks for all your constructive and helpful inputs. I learned a lot.
  11. When I right click and choose open in a new tab, a new tab opens but it closes right away. Open in a new window or open in incognito window opens those windows but no information shows up.
  12. And here is the RAW file: https://www.dropbox.com/s/el8hxdgc8acgvnr/AZsunsetRAW.NEF?dl=0 Trying your images is next. Tried to download updated ACR version, but it crashed the program and after recovery, the same old version still shows.
  13. PSE only supports sRGB and Adobe RGB for importing camera files, therefor the ACR version I have (supposed to be the most recent, 13.0.0.612) doesn't allow me to choose Prophoto RGB.
  14. Elements only supports sRGB and Adobe RGB. The green patches appear in both in 16-bit after haze removal. And yes, it seems to happen when only the red channel is clipped in highlight areas.
  15. Andrew, The green issue happens to several images, but it seems to happen only when the images have blown out areas in the highlights. Pure speculation, but I could see this happen if the OOG warning feature in Photoshop was not totally removed in the process of "dumbing down" the program to become Photoshop Elements. And more speculation: I don't think it is an image file issue, but a PSE issue.
  16. Totally agree. I can tweak the ACR to not blow out any channels, but that gets me a very, very dark image. The questions still are why does the haze reduction in 16-bit results in the green patches that are not maintained when I save the file and do the blown out areas have anything to do with that (I think they do).
  17. Here goes: https://www.dropbox.com/s/c8ox9i40nvol2eg/AZsunset8bitjpg.zip?dl=0 https://www.dropbox.com/s/2cm7jdqrj55f5f1/AZsunset8bitPSD.zip?dl=0 https://www.dropbox.com/s/7qdzex5x3gybgs7/AZsunset16bitjpg.zip?dl=0 https://www.dropbox.com/s/ndk7wzz8o0nm9a1/AZsunset16bitPSD.zip?dl=0 The jpg's are low resolution screen shots, the PSD's are the complete files edited in my PSE program, including haze removal.
