Finally getting serious with digital photography.
Brief intro: Taking photo's seriously since 1980, 35mm film, Blad 500 c/m, my first digital to play with was a Dimage 7. Shot weddings, less models, photo-journal in the Army Reserves for a bit. Never took it on as a prof. but a serious hobby that I made a little coin with from time to time. Okay, just got my Digital outfit:
EOS 20D, Sigma 12-24 EX, EF 24-70 f/2.8 L, EF 70-200 f/2.8 L IS, Flash Canon 580. I have CS2, plan on doing most of my work in RAW. Considering the Canon iP8500 or the EPSON 1800 (haven't done enough research yet, so opinions welcome on that).
Finally my question: I currently own SpyderPro (phtocal, optical, precal) and can get an upgrade discount of 25%
on Spyder2Pro but can't tell from adds or anywhere else what my benefits will be. Basically is the newer product worth the 225.00 with discount?
