  • Without having your original image it is hard to know for sure.   I suspect that you scene for the given exposure had too high a dynamic range compared to your camera.  In other words, the sky was ...
  • Hi Draacor Any chance you could share the original image.   That would help get to root cause of the issue by allowing other to examine the original image. A couple things you could try. When ...
  • If you have any issues with IrfanView that does not meet your needs, all you need to do is use GIMP (its free) at https://www.gimp.org/ Just scale the image down to the number of blocks that you ...
  • Hi 2string You can look at this link for appropriate settings https://www.dpreview.com/forums/thread/4090048 The profile for the monitor ideally should be set by calibration hardware/software.  ...
  • Can you provide the original image including its embedded profile   I can show you a way to quantify the difference
  • Hi Reid The proof process is to preview the image by converting from the existing images color space to the target color space (sRGB in this case).  So for this purpose you leave the "Preserve RGB ...
  • Hi Reid If you are editing in a color space larger than sRGB, "and" using a printer/inks/paper that has a gamut outside of sRGB "and" you have images that also have a gamut outside of sRGB, then if ...

    Glad that did it for you Ben
  • I don't have PS 2017 yet isn't there the option to "Automatically open all supported JPEGs"? I would give that a try if that is still an option.
  • You could try the technique in this link: https://www.gordonmac.com/quick-tip-getting-rid-of-image-banding-in-lightroom/
  • A few suggestions. 1) Take the image that you exported and import it back into LR and check in the develop module at 1:1 magnification.  If the banding is gone, then it is not in the image. 2) If ...
  • Hi Mark First, here is a link that gives a better description of the difference between calibration and profiling: https://imagescience.com.au/knowledge/calibration-versus-profiling Typically, ...
  • Hi Fotoni It has already been shown that the raw file was not clipped. However, clipping is also relative to the color space that is being used. The image shown below is the sRGB color gamut as the ...
  • Hi Peter I don't think a FFT filter will do the job as FFT requires a regular pattern to remove and your sample indicates a more random pattern (probably due to something in the print surface or ...

    Hi Erik If you have a have a wide gamut monitor and display an sRGB through a non color managed application (I believe Windows Photo Viewer is an example), the you images will look too saturated.  ...
  • Hi Litetaker The answer to your question is dependent not just on a single image.  For this image, the degradation is not very noticeable (but there) at 100% viewing.  Both the random structure of ...
  • Replied in RAW vs. JPEG
    I agree Brad that the comparison is skewed.   Over time in general, the ooc JPEGs out of the camera have also improved and suit the needs of many needs without additional post processing.  For me, ...
  • Replied in RAW vs. JPEG
    Here is a post I made last year on some of the differences.  There are advantages and disadvantages with each so sometimes it is picking the best tool for your needs: http://www.dpreview.com/forums ...
  • Hi Philip Thanks for the info about the OS.  And the image is displayed via an OS application (e.g photo viewer), a browser, Photoshop, Lightroom, etc Are you viewing the monitors side by side at ...
  • Hi Philip One thing you either did not mention or I overlooked is what software you are using to compare the displays side by side at the same time.   Getting a match assumes that the software you ...
