About me:

When I hear somebody say, 'color management is hard' I am always tempted to ask, 'Compared to what?'

  • Parts of the raw ARE indeed over exposed (Clipped) and the only way to know this for certain and with precision is to view the raw in something like RawDigger and view stats or Histogram: Percenta ...
  • And a reason they don't have a color gamit. Indeed.
  • I’m not convinced you understand this process of DCP profiling cameras. Have you ever tried to do so? Care to explain how to vastly different exposures of the same target produce the same DCP ...
  • That seems to imply you don’t understand how DCP profiles are created. I do. See my ACTUAL examples with vastly differing but not clipping exposures. https://www.dpreview.com/forums/post/63981867
  • If it clipped, the profiling software pops an error message. Simple, factual.
  • Exactly; as I illustrated. For differing profiles built using different software or lighting conditions, yes. The two profiles I made from the same target under the same illuminant (only difference ...
  • You don't want any flair if possible. For any capture of a target and in most cases. The numbers are meaningless because they are rendered values. You need RawDigger to find the actual values based ...
  • Two shots of a ColorChecker with vastly different exposure: This is a bit down in actual exposure and appears as such with default LR values (zero), Lstar of white patch ( first white) is 77: 1/4 ...
  • https://www.xrite.com/-/media/xrite/files/manuals_and_userguides/c/o/colorcheckerpassport_user_manual_en.pdf Not a video, but instructions. Start on page 10, examine page 14.
  • The color experts AND the people who wrote the software to build the profiles too. Page 14 of the ColorChecker manual: Adequately Exposed. Even steps are visible between each shadow and highlight ...
  • What OS? On a Mac my profiles are: /Users/-/Library/Application Support/Adobe/CameraRaw Are you sure you've got a raw selected in Develop? Rendered images will only show "Embedded".
  • Standard Size. Lightroom only deletes 1:1 previews that are more than twice the size of your Standard-Sized Previews as setup in your preferences. For example, if your Standard Sized Previews ...
  • It's always said beta and is pretty much unsupported but if it works for you, that's all that matters.
  • Which tells you nothing about raw exposure or clipping but more important, if the profile creation software didn't pop a dialog stating it was over exposed, you're fine. It will not allow creation ...
  • Adobe Bridge 2020 was released in April of 2020. It was free. It is free. Adobe Bridge, free use from day one. LONG before January of 2020 that is: https://en.wikipedia.org/wiki/Adobe_Bridge Adobe ...
  • Good example of how to ruin a scene from one of the most beautiful shot films in history: The point is ugly (subjective) WB that should not be. One real, not balanced to R=G=B Incorrect WB. Ugly.
  • Indeed and not necessarily the environment. My 4990 clogged if not used nearly every day. The 3880, not. P800 is the same.
  • DNG is a container. All the specifications are openly documented and anyone who wishes to write a DNG can do so. This is just like TIFF and both formats are owned and controlled by Adobe. You can ...
  • And his first post here. Best to ignore this sales pitch. FWIW, my 10 year old 3880 which goes months without printing has never had a clogging issue.
  • I do, no they are not the same because of some of the reasons explained. So say camera A tells us the scene is 5000K as does camera B. 5000K is a range of colors: See line e-f ANY color running ...
