I got a Macintosh PowerBook G3 (from 1998) last week and after finding out that it has a scsi-port I decided to try to get it working with my DCS 420. Well, today I finally got the right HDI-30<->DB25-SCSI-cable and Photoshop old enough (5.0 LE
). I copied the DCS Acquire 5.6.5 -plugin to Photoshop's plugin folder and it worked!
Colors seem to be a lot better than with ACR, but there isn't any exposure correction, anti-moire or noise reduction (all would be very usefull with this camera). I also found out that my 420 has the newest 98-firmware and that the clock isn't Y2K-ready.
