  • This might help: Everything you thought you wanted to know about color gamut A pretty exhaustive 37 minute video examining the color gamut of RGB working spaces, images and output color spaces. All ...
  • TIFF is far more of a universal open file format. It cost nothing for other software companies to support TIFF. PSD is a proprietary format and companies must pay Adobe a fee to use it. As such, ...
  • Indeed. When I was teaching at a workflow for Art Wolfe in Seattle, he wanted to test a number of different temps of Solux bulbs and for a gallery, 3500K we all agreed looked much better. For ...
  • Nothing really special about Ott-lite and it can't compare to the Solux. All Fluorescent's have a very spiky spectrum due to the nasty mercury in them. Solux are not Fluorescent and have about the ...
  • FWIW, that would be metameric failure or metameric mismatch. Metamerism is two (2) samples with different spectra compared to each other with a given set of viewing conditions, produce a match . ...
  • Agree 100%. I hear people say " but my display is calbrated " and when you ask ' how ' you hear "I read I should use this White Point or that Cd/m2 ". Unless we know the exact specifications of the ...

  • I don't believe so if indeed Dx0 is using Adobe RGB (1998) for processing from raw. It is wasteful in it defines colors that fall outside the spectrum locus (the gamut of human vision if you will) ...
  • They have the same number of addressable color vaules, yes! We hear all the time " Adobe RGB has more colors than sRGB " and as you point out, that isn't true , the number of addressable color ...
  • Very, very close. Actually Melissa RGB is the name for the color space that represents the histogram and RGB percentage numbers and it is ProPhoto RGB gamut (it uses the same primaries) but unlike ...
  • No, just the opposite. Shoot in Adobe RGB (1998) as it has a wider color gamut. Convert to sRGB for when you need sRGB (posting images to the web). You have the best of both worlds. IF you capture ...
  • That video is technically way off base and wrong in a number of areas of color science. FWIW, if you incorrectly treat sRGB as if it were Adobe RGB (1998), it looks too saturated . If you treat ...
  • I agree completely! And I'm OK with the dumb it down or KISS philosophy. I'm not OK with people dumbing stuff down by using technically incorrect data points trying to convince others it's too hard ...
  • Replied in No testing
    Not certain that value (98%) is accurate or not but there is also more to all this than just gamut and containing all the colors. Especially for print output. This is geeky but for those that have ...
  • Replied in No testing
    Here's another for the sRGB religious zealots. You saw in the last post that Adobe RGB isn't large enough to contain colors my 3880 could produce. Now here is a real world image of some yellow and ...
  • Replied in No testing
    What spec's and what output media are you talking about? The only way to do this (correctly) is by plotting in 3D the gamut of the ICC profile that defines the output against an image. Which is ...
  • You came to that conclusion using what testing methodology?
  • Replied in Somtimes
    I absolutely agree! In fact that is the best use of sRGB today.
  • You still on that topic? What a waste of time. Get over it. It has nothing to do with this topic! It is an editing space, one converts from it to an final output space based on the needs. You are ...
  • That's nonsense, the books out of print and further, you don't appear to understand what you're talking about. There is no final out of ProPhoto RGB, it's a working space. You decided there isn't a ' ...
