Hello !
I have been working for more than a year on making a slideshow from about 1000 photos I took trekking the Himalayas (with a Pentax Optio 330). I have worked with Photoshop 6 for several months on a Thinkpad 380Z portable computer, then again a few months on a laptop computer (I forget what it was) and now with Photoshop 7 on a third computer. Some photos which looked beautiful when seen on my Thinkpad now look like they need to be brightened a lot… When noticing this, I bought a book on Photoshop (Adobe Ps 7, New Riders) and tried to learn all about color profiles. Not easy (probably not simple from the start, + reading a French translation). I now have a lot of questions !
1) Could you provide links to tutorials explaining the Photoshop color management system ? Being a computer engineer, I like to know how things work inside, and I have not fully understood color profiles, workspaces, etc.
2) From what I understand, I should build a color profile for each of the PCs on which I worked, then attach this profile to all photos which were retouched on each PC ? How do you recommend to do that (I still have the Thinkpad, but I have no more access to the second PC I used) ?
3) For calibrating the screen on which I work, I have heard or read about expensive software. Can one not find paper color samples to place near the screen, then calibrate the screen colors using these samples, which could be very inexpensive ?
4) After learning about color profiles, I switched the Photoshop RGB workspace to "Adobe RGB (1998)" (yet another source of disparity !). I have noticed that when suppressing the embedded color profiles, the photos look better ! Is that normal, should I therefore suppress all embedded color profiles ?
5) My slideshow is meant to be displayed on a screen with a video projector. However I have no video projector of my own and I borrow one when needed, so it is not always the same. Before displaying the slideshow, I suppose I should ideally also build the color profile of the video projector so as to display things right ?
6) Last : is it possible that some slideshow software (Acdsee, Irfanview, ….) do not take into account embedded color profiles so that taking pains to make things right is perhaps useless ?
Thank you in advance for your answers
