Re: [Digital BW] Automating Spectro Measurements

2003-07-09 by Scott Hendershot

Ernst,

I played around with different techniques for scanning by hand but I guess I
just don't drink enough wine. This auto indexer has been fantastic. I
profile alot and I just mount the target onto the carrier sheet and go do
something else. In ten minutes or so I have a data file to import into
Profiler Pro.

It's been handy for measuring other targets as well. I wrote software to
measure grayscale output and generate photoshop map files to linearize and
correct grayscale images for making negatives. I would have killed myself by
now if I had to measure targets by hand.

Scott
