Forgive me: PS and LR images have different colors

I hope this topic hasn't been beaten to death, if it has please kindly provide me with a link to the topic with the least amount of flare possible

I have a 27" imac + an HP LP2475. Both have recently been calibrated with spyder3 pro. I understand one monitor is wide gamut and different resolutions than the other but why does the same unedited image have different hue's in LR and PS when on the same screen?

I don't know how to check LR color space but PS is set to the ICC profile that Spyder 3 has generated.

Edit: I noticed that the problem actually occurs when i drag the image from my mac ( non wide gamut ) to my HP monitor ( wide gamut ). I would like to do my PS editing on the HP as it's more accurate with colors... well supposed to be anyway

Totally confused and appreciative of any help from the wise people here!

Lightroom has a fixed working space -- a "version" of the wide-gamut ProPhoto working space. But, heads up -- Photoshop needs to be set to a color space, not your monitor's ICC profile. So, initially I'd set it to sRGB until you are used to this stuff. In Edit/Color Preferences you want to change your working space to sRGB, and then go over the options of how to handle images that have a different color space or are missing color space info.

You can also set sRGB to be your Lightroom space for exporting an image or editing it in Photoshop. Run some images through LR to Photoshop and make sure your settings are all what you need them to be. Also, Camera Raw in Photoshop can be set to convert to sRGB by opening an image in LR and then clicking the little link below the image preview.

Once you get everything in sRGB, if your monitor is properly calibrated, things should look good...

So this is what i'm seeing on my wide gamut screen. the left image is from LR without edit and the one on the right is the one from photoshop.

if i move the PS image back onto my Imac screen there is a very small difference in color. However, if i move it back to LR it seems to change the image color once i release the mouse from dragging it over. It's like its adjust the color profile but to something different from LR.

I know this is probable something dumb that i have done. Again, i appreciate the help.

I'd say monitor profiling -- they look pretty close to me.

Look closer

To clarify: You opened the LR image in PS? (Cmd+E)
Using these color settings?
(Since the file in PS is a jpg, it should be "CR2" if you used Cmd+E)

Also: Tick the first checkbox (profile mismatch) for troubleshooting)

So, you are using sRGB as output color space in LR.
Have you tried a different color space? (Not that I think it is the problem in this case, but it could cause a difference since LR uses a wider colorspace then sRGB)

Weird.
Both LR and PS should handle dual monitors just fine.

Both monitors are calibrated, and each uses the correct profile? (Check the system prefs)
Both LR and PS use the same screen as "main" screen?

Works on my G5 with LR2 / PSCS4. Images look identical in both LR and PS on both my LaCie CRT and my Apple LCD. (as far as the screens gamuts allow)

How does the image look on both screens if you use dual monitors in LR (shift+E for loupe view on the second screen)
How does the image compare in PS when dragging from one monitor to the other?

Screenshots from my system, copy-pasted together. Converted to sRGB.

OK, thanks for the help.

I checked to make sure that each monitor was on the correct profile and they are. When i was taking screen grabs and trying to cut and past them together in PS i noticed that the screen grab from each screen had it's own color profile and when i went to paste the SS ( screen shot ) from my HP lp2475 to my SS from the imac screen PS asked me if i wanted to convert color profiles. I chose to preserve each color profile... when i did that the image ( hp monitor ) changed profile once i pasted it to the imac SS on my mac screen.

I'm not a tech guy but i assume that each monitor has it's own ICC and is keeping that profile assigned when i move the image from one screen to another when using PS. I'm gonna go ahead and assume that i may have to recalibrate my screens.

I'm gonna wait until i hear from you guys before i do that cause i get pretty acurate prints from the current calibration. I just want to Edit PS on my HP LP2475 since it's more accurate.

here are some SS's - the images in PS were opened via cmd + E

The images are a tad small, but you can easily tell the difference by the color of the leaves.

both LR - the first one is my HP and the second my IMac screen - pretty close. I'm happy with this

They should.
The screenshot should look identical to the "screen that was shot".

You should have converted to sRGB. Now the screenshots won't look like they're supposed to in non-colormanaged browsers.

Open all screenshots, convert them all to sRGB, then copy-paste.

That's how it looks: The image in PS look less saturated on the (wider gamut) HP.

If I open the HP/PS screenshot in photoshop, convert from HP to iMac profile, then assign the HP profile, it looks identical to the others.

So, somehow, PS doesn't "like" the HP monitor profile.

Both profiles are in the same location, with same privileges?

Does this also happen if LR is not running?

I've had it happen that PS used a different monitor profile then the rest of OSX.
Took me a while to figure that one out...

You might try this: Open PS, color settings, then click here:

Well, everything looks identical, except the image in PS on the HP. Which is weird.
I've not seen this behaviour before...
Not sure what causes it either.

This looks good. So I'm assuming that only the HP on PS doesn't look good.
