I've been doing some more computer research as of late. Trying to figure out how to best speed up my photoshop workflow. So yesterday I wrote Rob-Art over at Bare-Feats to ask a mac question and he answered well and also pointed me to an online guide I think might be useful to some of you. Fascinating stuff.
Apparently, my waiting 30 seconds to save my 30 layer, 16bit PSD files is something I can't do too much about. Has to do with the way Photoshop is single threaded while saving. Sad.
Anyway, here you go. Excellent read for digital darkroom dorks: http://macperformanceguide.com/index.html
