Re: [APML] PowerLook 3000 Dynamic Range



Hi Matt:

We have a Umax Powerlook 1100 at work so I hope the software is similar ( I asume your using a PC). I've had a lot of luck lately with tough transparencies (no negatives) by going into the advanced tools and using the "curves" adjustment there and really pushing it hard in order to get as close as I can to a decent tonal range. Then tweaking the Gamma to smooth it out. The final scaning is done at the scanner's base optical resolution (the 1100's is 1200x2400 so I set it to 1200dpi) AND the final percentage I want to enlarge the original, so a 2 1/4 image might be set at 1200dpi and 400% . This usually helps the sharpness and tonal range so I can tweek it a little more in Photoshop. It usually works but there are times when we still have to send tough images out to be scanned on a drum scanner. If you've already tried this technique then your image may be a candidate for a Drum Scanner.

I'm having trouble scanning a shot without clipping using MagicScan32 V4.5. The shot was 60 minutes on PPF 400 of the Sagittarius Star Cloud at f/6.7. Since it is perhaps the brightest extended object I have ever photographed, I may have achieve the highest densities ever. I think it may exceed what the scanner is capable of (3.6 Dmax). I've tried varying all the settings.

Any suggestions?
