  • 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 ...
  • Replied in Never mind...
    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 ...
  • Hi WIMorrison Here is a link to an article and tool all about JPEG compression.  This particular page as a listing of many camera, scanner, software JPEG quality comparisons (which is not an easy ...
  • Thanks for the link CanvasPrime.  Good news, I could change images in batch to go back to original crop. I imported you ARW file which opened with the 16x9 aspect ratio. I then created a number of ...
  • I think you got it Jones! BTW - My background is electrical engineer and I cut my teeth with Andrew's book when it came out and that did it for me :)
  • You have seen it already yet posted above with my suggestions: http://www.dpreview.com/forums/post/57560215
  • Your best bet is as highest priority is reduce the pixel dimensions to the least that is needed.  Going much over 300 ppi for an 8x10 image does not add much. Only after resizing to a size just the ...
  • I would have to agree about the compression. JPEGsnoop indicated it was likely it was saved with Photoshop with quality setting of 1. I tried that on one of my images and the compression tables in ...
  • Hi Jones and Andrew The color space for the full size JPEG was in Adobe RGB which is a part of the problem. From the high bit image, you might have less banding if you were in sRGB The compression ...
  • Any chance you could provide the Raw file on dropbox or google drive to give it a try on our end?  I don't believe my camera allows in camera crop with which to experiment.
  • This link might help.  You want to choose "Original" as far as the crop setting and then copy those crop settings (I have not tried that out) http://www.lightroomqueen.com/whats-new-in-lightroom-4-2/
  • It might help to focus on one or two images instead of a link to a whole portfolio.  Also, it depends on what you want e.g. some appreciate highly saturated images and others want something that ...
  • I agree with Bob TIFF file format supports a wide variety of compression including none, LZW, ZIP, JPEG, Indexed (or various flavors).  Not all editing software supports all modes. You did not ...
  • Hi l_d-allan Here is a link the the Korean web site with the specs: http://www.wasabimango.co.kr/bbs/board.php?bo_table=product_1&wr_id=35 It does include further down the compatible graphics cards. ...
