Lightroom ↔ Photoshop color conversion
« on: November 30, 2007, 01:06:18 pm »

Hi everyone,

I'm having problems with my photos starting out nicely in Lightroom 1.3 and looking terrible when handed off (using Edit Photo with Adobe Photoshop CS3 - command-e) to CS3.  I'm on Mac OS X.5.1 though this problem persists from when I was running OS X.4 Tiger.

Once I set everything the way I want in Develop, I hit Command-E and hand the photo off, but am disappointed when it shows up washed-out, as if a 5% opacity white image was blended on.  Both Photoshop CS3 and Lightroom are set to use ProPhoto RGB.

Attached is an example screenshot.

I use ColorEyes Display with a Monaco Optix XR Pro colorimeter. I don't believe this is the source of the problem as I'm looking at the PS and LR photos -- identical TIFF files, on the same Apple Cinema Display monitor.  Besides, the working space is ProPhoto RGB.

Anyone have suggestions to remedy the discrepancy between Photoshop and Lightroom?
Or is this in fact normal?  Any suggestions appreciated.

Color settings in Photoshop are as follows:

Settings: Custom
-Working Spaces-
RGB: ProPhoto RGB
CMYK: U.S. Web Coated (SWOP) v2
Gray: Dot Gain 20%
Spot: Dot Gain 20%

-Color Management Policies-
RGB: Preserve Embedded Profiles
CMYK: Preserve Embedded Profiles
Gray: Preserve Embedded Profiles
Profile Mismatches: Ask when opening

Conversion Options: Adobe ACE
Intent: Relative Colorimetric
Black Point Compensation and Use Dither ticked

Thanks Jeff,

Thing is, it's on the same monitor -- same profile (as far as I know) for both LR and PS.

Or is there some other profile setting I need to look at?  It's a bit like where's waldo with all the possible settings, so any further instructions would be helpful.

Not to sound smart ally, but it almost look like when you when Photoshop CS3 soft-proofing is enabled, which would have the image look washout when compared with LR

This is what I did yesterday on a.DND file:
Opened in LR
Saved as a high Jpg.
Converted embedded colour file to Adobe RGB.
Layered and pixel played.
Printed.
Excellent.
 All equipment profiled

Your color settings seem fine. Are you exporting as ProPhoto RGB? That shouldn't be an issue since you have the Preserve Policy.

With your profile package, can you make a larger LUT based profile? I'd try that. I do recall an issue with some profile packages too (LUT versus Matrix) between the two applications which don't treat the data identically.

Also, you really need to view both at 100% view (so in LR, 1:1 when comparing).
