  • Allow me a question! There is so much confusion on that topic, I really don´t know whom to trust! You sound to me like a real expert so I think it´s the best idea to ask you: What are the ...
  • Right. My path is 8bit. I see! Use dither is ON. I was wondering why the visible dither did not get reflected as different values when I hover over the noise. Solved it myself. I was using 11x11 ...
  • Loaded in PS I clearly see banding. But when I convert it down to 8bit the banding is gone! When I look at the 8bit conversion at 3200% I see dithering-like noise (not so before in 16bit mode) that ...
  • Just to inform you (no claims intended): Just download Babel Color trial and did some testing. I can see the difference between 111,0,0 and 112, 0,0,  though, other that in PS it´s much less pronou ...
  • It says: "Score 0. You definitely should run for president!" But since I did that in Firefox (not knowing if color management applies for that site), being on a wide gamut display may have helped...
  • I fully agree! But not with drawing conclusions from truncated Lab values in PS. See elsewhere.... Yet you used PS in your example. That´s all I intended to point out. deltaE is derived from ...
  • Yes and no! I made a mistake in stating that your general statement "Every distinct device value does not neccessarily translate to a distinct color" (my words) was wrong. For the misleading aspect ...
  • I must apologize! Infact I DID say in some earlier post the following: "You said: "In some cases, TWO of the same device values are the same color" This is wrong. " Sorry for that! You are right in ...
  • Oh, man! How often are you gonna repeat yesterdays news? Did you ever read my replies??? I stated three times now that I can NOT spot a difference on that (let´s call it) "teal example" of yours. ...
  • We are approaching 1 AM here in Austria so I will only answer to that point for now: Who the hell do you think you are talking to? Bothering me with some rotten old optical illusion every student ...
  • No, you CAN´T! I´m talking principles here! It may be the case (most of the time it surely is) but it need not be so! I´m still talking about the example you gave by pointing to two Lab values ...
  • See bottom line(s)! What were your requirements again? 100%, color profile sRGB, soft proof. I met them all, and I don´t see why Photoshop other than Bable should exaggerate differences. What would ...
  • I never said otherwise. I just tried to draw a line here between the SET of real numbers (set theory) as opposed to "digits", which are discrete integers. Human perception IS a real and analog ...
  • Some annotations: • I know that color space matters here, so I did it in sRGB (worst case scenario). • "If you have very good color vision". Color vision depends on many circumstances. You may NOT ...
  • The doc is set up in sRGB, viewing at 100%, no matter soft proof on or off: I still I see the difference. I tried the same with your values and I must admit that I cannot see the difference. But I ...
  • Preface: Lab is a mapping of REAL ANALOG phenomena thus it deals with real numbers--as opposed to discrete integer values/bits. Lab space mathematically is a "real number" space containing an ...
  • Sorry for my distractions from your concerns! The side aspects I´m dealing with here are infact not overly important but sometimes a man has to do what a man has to do:-D I personally don´t feel ...
  • You mentioned deltaE (which appears to me to be a physiologically useful quantity like dB) , and I understand your basic argument derived from that concept, which is: it doesn´t make sense to ...
  • "Color isn’t a particular wavelength or property of light, it is a cognitive perception. Color, is a perceptual property, something that occurs deep inside our brains. So if we can't see it, it is ...
  • Oh, I don´t care about someone being rude (which I didn´t feel digidog was anyway) as long as he capable of offering me some insights!
