Anyone know a reason why when i view a picture in the software that came with my 20D it looks great, but as soon as i open the exact same picture in photoshop 7 it gets a orange tint to it and i have to play with the levels to try and get it back right?
Seems like a un-needed step.
help!
thanks

most likely happens because of the color space you're working in. The Canon soft sees in sRGB (I think) while you most likely have your color space in PS as AdobeRGB

so should i set Photoshop to sRGB? If i do that, will that mess up anything other than photos i do in photoshop?

AdobeRGB has a larger color gamut, so I'd leave it like that. How do you shoot? Or how do you convert your RAW files? In AdobeRGB, or sRGB?
AdobeRGB is the color space of choice for most photographers I believe, despite the fact that the end image will be in sRGB (whether it's printed or just displayed on a monitor)

I shoot in RAW, then i use the EOSViewer to edit the RAW files then i save as a jpg from there. It doesnt give me an option to save as adobeRGB or sRGB within that program i dont think.
Even when i open the edited pic from EOSviewer in Noiseware its still perfect, but as soon as i open it in photoshop it turns orangeish.

Last time I saw something like that, it was an incorrectly set up Photoshop monitor profile. Did you use Adobe Gamma, when you installed photoshop, or did Photoshop ask you if you wanted to profile your monitor? If so, did you?

The color space you are working in has nothing to do with colors coming our "different" or weird because PS is smart enough to convert from one color space to another although there may be a possibility that some highly saturated colors may get clipped and become less saturated.
The most likely cause of non-matching colors in PS compared to other programs is the fact the monitor has not been profiled or has been profiled incorrectly, as was pointed out by griff2.

griff, it has been so long i cant remember... should i re-install it or is there a way i can set it up again.
Im probably not helping matters that i have dual monitors...

Sorry I am a newbie here but I can put in my 2 cents. The 20d defaults to sRGB, if you are shooting RAW I believe when you open up the RAW in photoshop you can change the default color space to Adobe RGB. You can also adjust that setting in your camera I believe also. You may want to check those two settings before converting to TIFF or RGB for processing.

ok. my main monitor must be correct... my flat screen must be way off because i switched photoshop to my other monitor and it looks WAY better!
I wonder if there is a way to calibrate both monitors... although they are not the same monitor.

Aha. Are the two monitors the same or are they different? I use two monitors at work, one an LCD and the other a CRT. I installed Photoshop when I was using only one CRT monotor, but when I got the LCD Photoshop wanted to profile it too, I prevented this from happening.
You could try running Adobe Gamma on your best monitor - assuming they're different.

A RAW file is raw. The color space is assigned when converting into Tiff, or JPG

You can install multiple monitor configs in windows (In XP anyway, not sure about older models), that way,then you should be able to change the driver for each monitor and profile seperately.
I have three monitor drivers installed on my laptop. One driver runs the laptop display, the second driver runs when I plug into workstation at work and use a CRT monitor and the third monitor is for when I take the laptop home and plug into my server. Each of these have been profiled seperately for optimum use with PS.

Ok that's the problem. Photoshop's profiled your main CRT monitor, and is applying this profile to the LCD. You could have a generic profile for both monitors, but I would advise against that as what you print out will have no relation colour wise to what you see. Stick with the profile you've got for the CRT, unless you prefer the LCD, in which case create a profile for the LCD (Adobe advise against this) and make that your Photoshop monitor.

Can these profiles be switched on the fly? I If decide to drag photoshop over from my CRT to my LCD will Photoshop know which profile to use?

I don't believe Gamma works for LCD. You would need something like Liquid Color http://personalcomputing.portrait.com/us/products/lc_overview.html Haven't used it myself; just giving an example.

Are you using a switch box for your monitors and do you press "Function" and the relevant function key to switch over displays or do you have both displays running at the same time? That is, the CRT is plugged into the back of your laptop?
When I press Function-F4 on my laptop, the monitor driver changes. It only works when I am docked on the workstation. When I take the laptop home and plug it into server, I have to change settings manually :-|

I suspect Tmizzle is, like myself, using a dual head display - both monitors sharing an extended desktop, to effectively become one BIG monitor; in such a situation, I think only one monitor profile can be used at a time by Photoshop, and the solution would be to have Photoshop sitting in a window of the profiled monitor.

yes griff, that is exactly the situation!
sometimes images look a little flat on the CRT and i drag photoshop to the LCD and work there. With photoshop on the CRT my pics look like they should. Seems like they all need auto levels applied but then they are pretty much fine.
