Adobe RGB (1998)

[sherridge101]

Hi all

Sorry to bring up again.

I've assigned the Adobe RGB 1998 profile to the ICC slot in the VFB.

Rendered out a red. Opened in Photoshop with Adobe RGB profile, but the reds are different.

We use Eizo monitors, set to a printing profile.

Cheers

Are there any other corrections enabled in the VFB, beside the ICC? If so, try disabling them and compare again.

Hi Alex

Nope, just the default settings.

I'll pm the scene and ICC profile, if ok.

Alright, send the files and we'll have a look. Thanks.

Just following up on this.

I know we didn't get anywhere with the files sent, but it would be good to get a solution to having the same colours in both the VFB and photoshop.

Might be an idea to have this in the manual too, as it's pretty fundamental.

Not sure what to put in the manual, since photoshop seems to apply the color space in its own way. If I remember correctly, the pixel information was the same, but some additional display space was applied in photoshop that made the image look visually different. Any suggestions are welcome

You might want to search the Max forum, I think there are a few old threads about this already.

Best regards,

Cool, cheers. I'll take a look.

Shame there's not a process in place for the VFB and Photoshop to look the same.

Cheers

To update:

I've loaded the Eizo monitors ICC profile in to the VFB and the colours look pretty close (or certainly closer) to the rendered exr.

I'm coming at this from the max side rather than Maya so take this with a small grain of salt.... I thought this was the result of maya (or max) not being color managed. We can compensate for this by loading the calibrated monitor profile into the VFB's ICC profile so VFB colors will visually match photoshop which is color managed. However, if you load up AdobRGB1998.icc in the ICC profile the crucial step of conforming this to your monitor display characterization does not happen. This does happen in photoshop however (as intended so two different monitor essentially display the same calibrated images). With this in mind you can see why the two images (VFB and PS in Adobe RGB) will never match. I think the only way to have this working would be to have a separate monitor profile in the VFB as well as a color space profile.

I could be completely wrong about this though!

I think there was something about that specific icc profile that made it incompatible with the VFB, but I might be wrong (if memory serves, it lacked some information that the vfb requires... or had a different type of contents that the vfb can't work with).

Cool, cheers for the info.

Prior to having the monitors ICC profile loaded in the VFB, the colours were way off, so this is a great improvement.
