Grainger Rainbow showing clipping on wide gamut monitor

Discussion in 'Digital Darkroom' started by steve_ruddy, Nov 24, 2016.

  1. I just purchased a newly released Eizo CS2730 and wanted to test how much of the adobe RGB 1998 color space it can handle and I'm seeing a lot of clipping. I calibrated the monitor using Color Navigator and picked native gamut during the calibration which is supposed to be 98% of the Adobe RGB color space. Here is a photo of the image in PS with the Adobe RGB colorspace applied and proofed with my monitors profile. Why am I seeing out of gamut warnings?

  2. The out of gamut warning tool in photoshop is not accurate. It is not intended for this type of test

    This told 'tool' is kind of useless and predates ICC color management in Photoshop 5, best ignore it:
    The Out Of Gamut Overlay in Photoshop and Lightroom

    In this 25 minute video, I'll cover everything you need to know about the Out Of Gamut (OOG) overlay in Photoshop and Lightroom. You'll see why, with a rare exception, you can ignore this very old feature and still deal with out of gamut colors using modern color management tools.

  4. Listen to Andrew.
     
  5. Thanks Guys, I'll check out your video now Andrew. You didn't mention if the video explains how to test the color space of
    your monitor. If not how can I do it?

    Thanks
     
  6. OK I just watched the video. It looks like your saying that LR's monitor gamut warning feature is accurate. I wonder why they haven't made PS the same? After all I did pick my monitors profile for proofing in PS. Anyway when I did the Grainger Rainbow test in LR it passed all colors except a minuscule amount in the white area. Since you all say this chart is old and not useful I found a different one. What do you all think about these results? It's showing a lot of clipping in the color bar, see link below. I did calibrate my monitor using the monitors native color space which is supposed to be 99% of the Adobe RGB.
