I watched with great interest this great tutorial a couple of times, until I started understanding the whole process and begun looking into the details of it.

I have noticed that in one of the sections, Jeff mentions that ProPhoto RGB is a gamma 1.8 color space, while Adobe RGB is a gamma 2.2 color space.
I also found this information in this article on the LL website: http://www.luminous-landscape.com/tutorial...photo-rgb.shtml

And here is the confusion - when calibrating a monitor you need to select the gamma in which you will be working. Which means you need to have 2 calibration profiles for each gamma, one for 1.8 and one for 2.2

Does this mean that when switching between ProPhoto RGB and Adobe RGB you also need to switch monitor profiles for correct color display ?

Thanks for clarifying ...

The Gamma (actually TRC) of the display and the working space do not have to match. They share the same term but this tone curve is being described by two different beasts. So no, you absolutely do not need to calibrate a display to a TRC that matches a working space.

Andrew:
Just trying to clarify.  What's important, here, is to only switch the gamma of the working color space in the Photoshop color settings to 1.8 if working in ProPhoto, as was suggested on the Camera to Print video, but one does not need to be calibrating a monitor to 1.8?  Leave monitor at 2.2 but change gamma to 1.8 if working in ProPhoto?

Thanks

Working space gamma and display gamma are totally separate and independent of each other. They do not need to match.
