The calibration tools available including the spyder allow for calibrations for different uses. They can be set for web viewing, ICC profiling for a printer/paper combo, CYMK separation, various halftone, web printing etc.

The kiosk manufacturers have 'standardized' profiles for their systems. Perhaps for most users the easiest way to get the 'right' one is if your printer offers it via the web or on CD. The you can use that profile to calibrate your screen accordingly.

If what you want to do is view web photos, there's an option or a right click pull down menu that allows for 'WWW profile or web viewing' dependent upon which module is loaded.

The gamma (effective brightness) is biased differently for PC's and MACs but they can easily be set to the 'other' one.

One other consideration is to get a color target and/or greyscale target as well. The Pro Spyder pack comes with at least one I believe. Then you can calibrate/profile your camera and scanner.

Once they are profiled, (for the camera in the light of the actual shoot, custom WB, etc) then color correction is a mouse click away for 99% of you photographs. It even works with film, just make sure the target is evenly lit and the whole target is in focus. Or just shoot a single photo of the target by itself and use that as you reference.

If you have other questions, let me know if I can help.There are a whole list of 'tricks' to make sure this all works to the optimum.

The first and most important one is make sure your monitor is clean and dust free before profiling!!

Have fun!
