Photokina brings two good software announcements for digital photographers: Lightroom Beta 4 and Aperture 1.5. My Windows workflow means that it will be Lightroom B4 that I'll be giving a go -- my previous experience didn't wow me, but I'm willing to see if this latest rev is gentler on my CPU. Apple claims that Aperture will even run on Intel Mac minis, so my expectations are higher for Lightroom now.
