Will I need to learn this stuff from basics up, or are profiles available that I can plug in to certain programmes (if I knew what I wanted and where they should go ;-) ) In my simplistic way, I suspect I need a "photoshop" programme, (and before it now a RAW converter) which knows my "imput" device be it Olympus E 500 or DMR, and a sync device for my "monitor" and a final "profile" to what ever output: lab or ink jet printer. Too simple?
