Color Management in Adobe Camera Raw

[@rsmith02]

Excellent video that gave good insight into the dual illuminant profiles and how ACR works internally.

This is so useful.. very much appreciated, many thanks!

Thank you for this! Very well explained. Great Stuff.

Hi Andrew, so the histogram in ACR tells us when a color exceeds the selected color space. Is that right? If I want to stick with sRGB then I should edit my RAW photos in a way that makes them look dull. Or is better to edit in a larger color space and then let the program convert the colors in the final file? I have a monitor that can barely handle sRGB, that´s why i´m asking. The histogram may look nice in ACR but i´m not actually seeing the extra colors. Thanks.

In Lightroom: Two Histogram possibilities: 1. Without a soft proof is Melissa RGB (ProPhoto gamut, 2.2 TRC). With soft proof, whatever you select for soft proofing. If you select sRGB for soft proofing, that's the Histogram shown. In ACR, what you set for workflow options (the area that looks like a URL below the image) is what is shown in the Histogram. You can click on it to open Workflow preferences and toggle different color spaces and see the Histogram update on the fly. If you open a raw and toggle between sRGB and say ProPhoto, you'll see what would clip from sRGB that wouldn't in ProPhoto RGB.

Hello Andrew, thank you for this tutorial! Fantastic! I do have a question that has been very hard to answer elsewhere. If time allows, I appreciate any help. At 10:20 in the video you say to choose ProPhoto RGB 16 bit. But, what if my monitor only shows 99% of the sRGB spectrum? Should I still work with ProPhoto RGB in camera Raw? I am not printing, in the future I will. All images go to websites or social media. I shoot with a Canon 70D. Thank you again for the tutorial!

No display will every show you all the color gamut of a printer. And vise versa. There are colors you can capture and output to a printer you can't view. So do you funnel the colors so you can see them and not print therm? Even if you are not printing, you can always convert to a smaller gamut color space for display,. sRGB or maybe Adobe RGB (1998) or DCI-3. But you have all the color at your disposal rendering from raw into ProPhoto RGB.

HI! don´t trust the histogram in ACR OR LR they overexpose your raw file´s with 1+ stop.. :( if you dident know! :)

[@DigitaldogNet]

The only way to gauge exposure is to view a raw Histogram and ACR/LR do not provide one. You’d need RawDigger to do so. The Histogram in LR/ACR is showing you the current rendering based on MelissaRGB unless you setup a soft proof. It tells you very little about ‘exposure’ since it’s using the rendering and there’s no raw Histogram (yet; maybe someday) in ACR/LR. I’d expect most users images would be UNDER exposed by a good stop if they view a true, raw Histogram and they are not exposing ideally for the raw data.

[@DigitaldogNet]

No as Exposure only takes place at capture. It isn't a raw Histogram and thus tells you nothing about this exposure.

Poor quality sound, barely audible!

Sounds just fine on this end; try turning UP your audio.
