I am using a Mac cinima display to paint textures on but when I move to a SGI monitor alot of saturation is lost. Does any one have any suggestions to calibrate the two monitors so that the resulting video image is correct?
Thanks,
Dan
are you going acoss platform with this or are these two montiors on the same system or same OS> ?
If so just use a gray scale to adjust them to match.
amke sure you color temp are the same and game range.

Across platform Mac to Irix.

ahh well you do have a slight gamma shift bettween the two. Not as bad as btween IRIX and WIN . but it is there. I think you jsut have to plan for it. or adjust your fiels gama on the mac acodingly. I forget now waht the IRIX settings are.. but is not the monitor , its the OS differences.

You might want to check and see what kind of color calibration Photoshop is using. Especially photoshop 4 which automatically changes stuff to an iRGB pallete(pissed off alot of people in the prepress area because it wasnt widely used at the time). Photoshop 5 and above has an option to choose different kinds of calibration for you images. Your settings may very well be set for getting a good print, that of course is different then going from one screen to another and going to NTSC(Never the same Color). Look in the File > Color Settings.

Of course its always a tricky business trying to calibrate LCD monitors as even the best ones look slightly different depending on the viewing angle. Blacks I would imagine would be mildy milkier than on a good CRT monitor. Certainly check the photoshop colour settings first. That has been an endless source of problems for us as Macs default to Apple RG and PC's sRGB which may be fine for the web but has a smaller gamut I believe than Apple RGB. Its good to make sure that every copy of photoshop is running the same colour space. Apart from that you need to make sure your monitors are lined up correctly. Depending on how important the accuracy is you can try and match them by eye with a few grey scale patches, maybe 10%, 50% and 100% grey patches... For film work where colour accuracy is critical you need a probe really and the monitors should be lined up weekly if possible.
Having said all that we found discrepancy between sgi and PC display on the same monitor. ie. a dual input monitor with a LINUX box and Octane connected. The HP PC running a high end HP grahpics card had noticably less colour range in the blacks than the sgi. I would imagine this to be a feature of the graphics cards though..
