Sorry that's complete nonsense, you've either chosen a different profile or you have different conversion options set.

Re: my 1st post..red cast on Lacie 324/CS4 RGB to

Adobe tech support phoned me yesterday regarding this issue of which I
have an open case. He was looking at my attachments and told me he
could not see this red cast. He had 2 monitors - a calibrated Dell and a
calibrated imac Apple display. Neither had a hood and he was in a brightly
lit room. Can everyone see what I'm on about in attachments provided?
I'm using screen grabs and hoping differences in images will show.
I did suggest to Adobe that he try to see my attachments in a darker room.

Re: my 1st post..red cast on Lacie 324/CS4 RGB to

lets try it this way with no screen grabs:
- open file, flatten image using CS3.
- open file in CS3 and CS4, place files on top of one another.
- leave both files in Adobe RGB 1998.
- numerical values from picker points are virtually the same.
- go to Proof Setup and click Monitor RGB.
- use command Y to toggle soft proof on or off.

when toggling soft proof on and off on Lacie 324:
- both files look virtually the same on Lacie 324 with soft proof off.
- in CS3 there is some loss of saturation which
gives the appearance of a yellower, flatter skin tone
in Monitor RGB proof mode as compared to soft proof off.
- in CS4 the loss of saturation is more than in CS3
& it gives the appearance of a redder, flatter skin tone
in Monitor RGB proof mode as compared to soft proof off.
- if a Hue/Sat adjustment layer of master +4 hue, +5 saturation
is added to the CS4 file (when viewed in Monitor RGB proof mode only),
the files in CS4 and CS3 (both viewed in Monitor RGB proof mode)
look identical.

when toggling soft proof on and off on Apple display:

When the exact same test is done on my Apple display there is this loss
of saturation that leaves the skin tone flatter when Monitor RGB proof
mode is activated but there is no difference between CS3 or CS4.
If soft proof off - both CS3 & 4 images look identical.
if soft proof on (Monitor RGB) - both CS3 & 4 images look identical.

I hope this is a clearer presentation and I hope no one thinks I'm nuts.

On the first TWO attachments, the ones where you have the RGB and CMYK conversion - the Lacie on CS4 does look more red in the flesh tones of the CMYK only. This is more clearly visible by layering the screen shots on top of each other, and toggling them. Would help if the screen shots were higher res, but your man at Adobe is either blind or not used to judging these things.

I'll have another bash at trying to decipher your problem later on, but likely cause is CS4 is not recognizing the Lacie profile.

Re: my 1st post..red cast on Lacie 324/CS4 RGB to

If I ever allow the monitors into sleep mode - keeping the computer running,
going to lunch lets say. Upon waking, my Lacie profile must be activated again using the
Blue Eye software. Not sure what profile the Lacie defaults to but I was told by Lacie
that the surest way to activate my saved calibrated profile was by using the Blue Eye
software provided with the monitor. If I open my OS Display Preferences, I see that the proper profile is highlighted for the Lacie. But then activating my profile using Blue Eye does change the screen to what i think I should see.
This never happened with my last computer - IBM chip Powerbook with a Lacie 19" blue
CRT display.
Weird but I've grown accustomed to it as I wait for somebody to fix this.
My Apple display on my newer present intel iMac, never looses its assigned profile.
Not sure this has anything to do with the red cast issue but I thought it worth
mentioning.

Ah, so resetting the LaCie profile in the Bue Eye monitor software DOES work - puts the profile back and it looks correct then? On both RGB and CMYK docs? Just to confirm.

What I'm assuming now …Photoshop thinks that the correct Lacie profile is activated at all times. When you sleep it de-actives the profile and needs to be reinstated. Is this likely to be correct?

Re: my 1st post..red cast on Lacie 324/CS4 RGB to

Anything that I have sent has been with the current calibrated Lacie profile activated.
I have my System Preferences and Blue Eye software open upon each and every start up.
If I am working on files in PS for any period of time, energy saver is set to "never" for monitor sleep & occasionally I will check with Blue Eye to see if the monitor is displaying the proper profile. I have yet to find the Lacie drop its profile on its own. It is only after a wake up does the profile need to be reactivated. I learned this lesson on a client file. I am now very careful.
I only use sleep mode for email days & sometimes turn off the 324 completely on such days.
I should also mention that I do allow for time for proper warm up for the 324 as well.
But anyway if the 324 dropped its profile, wouldn't it effect CS3 conversions?
I have no issues with CS3 presently. Its preforming as expected.
I was informed this morning by Lacie that this is a Mac/324 issue which neither company has done any firmware to fix to date. Could it have something to do with intel iMac. I don't know. Is Apple competing with Lacie and thus hoarding info, would not surprise me. Do Lacie's other 500 or 700 series monitors have the same issue? I would love to hear from other intel Mac/Lacie users.
Do you think that this could be contributing in some way to this problem? Why only in CS4?

No it will NEVER affect conversions. That's all internal stuff, and not related to monitor profiling. Unless you do anything daft and try and Convert to a monitor profile of course. As I said in a previous post these output numbers are measurable, so its possible to assess profile conversions with no regard to what the screen is showing you.

Ok thats Lacie passing the buck. Most likely Their Blue Eye software is not playing correctly with system preferences. Its probably set to override what the system is doing. Unlikely to be intel related, but could be I guess.

Is there any way to deactivate the Lacie Blue Eye software completely? Still use it to Generate the correct profiles, but stop it activating, and allow your system to set the profile correctly? Use it in the same way as you are on the Imac screen in other words. You have to bear in mind that most of this software is probably designed for color stupid PC's - just assigning profiles in using mac Display preferences may be the way to go, with nothing interfering.

Now THERE'S a question - and that's where you may need some expert advice. It could be that the Lacie software was designed before CS4 came out and doesn't recognize it, OR that Adobe have actually changed something. This is the most unlikely of these two suggestions.

Re: my 1st post..red cast on Lacie 324/CS4 RGB to

I tried:
Restart iMac, open mac OS Display Preferences, pick an older profile made by Blue Eye - just to see a change on 324 screen, open same file in CS4, convert to CMYK, & seeing the same red cast on 324.
Opening same file in CS3, all is good as before.
Switched back to my current profile using OS DPref with the same resulting
red cast as above in CS4.
All okay on Apple display as before.

Thanks for your efforts Markzebra. Guess I'll have to see what Adobe found out. I sure hope no buck passing he said she said stuff starts flying around.
I will keep everyone posted.
cheers.
