Got my hands on the Photoshop CS3 beta, and I gotta say I’m impressed. Smart Filters are going to revolutionize the way I work in Photoshop. Non-destructive editing has been a long time coming in Photoshop (it’s been the standard paradigm for ages in some less-popular apps), but I’m happy to see that we’re getting there by stages. This brings us one step closer to the day that “Undo” is just an unnecessary extra. But even without the new features, I’d still love it for the native MacTel support!
Rather than do a full writeup, I’ll simply point you to somebody else that has already done a pretty good job.
Also, the beta doesn’t seem to be posted on Adobe Labs yet, so if you wanna get the bits yourself, just poke around on Digg.
