I'm using the original Spyder/PhotoCal bundle successfully on 98SE, and I recall that Adobe Gamma caused me a problem initially. Unfortunately the PhotoCal documentation didn't have any reference to this, which is a pity. You <must> de-activate Adobe Gamma if you are using a custom profile made by the Spyder (or any other 3rd party device). I can't remember how I did this, but I should think you merely need to remove it from your PC's start-up group. YMMV, but if you go Start->Programs->StartUp you should see all programs that are started this way. If you see Adobe Gamma there, just drag it off the start menu onto the desktop. Then reboot your machine. Note that the PhotoCal start-up app <must> be in the start-up group. If not, you may not have installed it correctly. If you right-click on the desktop & go to Properties->Settings->Advanced->Color Management, the PhotoCal profile should be associated with your monitor and set as the default (PhotoCal sorts this all out, at least it does for me on 98SE). If it's not then try re-running PhotoCal, as Adobe Gamma may have fouled things up. Also note that you should leave your monitor switched on for at least 2 hours for the colours to stabilise before profiling. Otherwise profiling will be a waste of time - the colours will drift as the tube warms up. The PreCal feature in PhotoCal should be used if possible to balance the guns prior to profiling, assuming your tube has controls to do this. Note that the LUT updates done by PhotoCal are not permanent: the LUT gets re-loaded by the video card firmware each time it's powered on. This is why PhotoCal <needs> to be in your start-up group, so it can overwrite the video card default LUT with its own data from the profile. If you still get a colour cast you may wish to contact ColorVision support as it then might be a genuine bug rather than a workflow problem. HTH Alan Rew - Turn off HTML mail features.
