Re: [Digital BW] IJC/OPM Tutorial Now Available!!!

Thanks, Steve.  

At present, IJC outputs its own test target, which has limited tonal 
separation between steps.  It starts with paper white and progresses 
gradually to maximum black in 26 steps.  The Eye One doesn't do well 
in strip reading mode with those small tonal differences.  It usually 
wants a test chart with gaps between patches, or to have no gaps but 
large tonal differences between patches to avoid read errors.  

I'll have to experiment with my own test chart if I can get IJC to 
output it for me.  Maybe there is an easy way and I just haven't 
figured it out yet.  Perhaps I can rename my test chart to replace 
the existing IJC chart.  Hmmmmmm........... I'll give it a try.

Joe said he will be adding automatic data import for the Eye One in 
strip mode.  He also plans to add support for other popular spectros 
like the DTP-41.

I appreciate the idea, and so does my wrist.
