I wish to test the Dynamic Range of my two scanners, a TANGO and an
LS-8000.
What do I need to accomplish this? I.e. what target would I scan?
How should the scanner be set up for the test?
Any procedural aspects to look for so I get a "true" reading?
Also, what would be the best way to test how large of a color
space/gamut the scanner can capture?
Possibly create profiles and compare the results with ProfileEditor or
similar application?
Any info on how to do this in a scientific method compatible way would
be of great use!
TIA
There are some new ISO tests developed / in development for
Digital Cameras and Scanners.
Dietmar Wueller of
http://www.image-engineering.de/
is one of the developers. You will find some references to tests
and targets on his site.
There are several tests done already in Germany of filmscanners
and film/flatbed scanners. All CCD. Published in C't and Color
Foto magazine. The LS 8000 / 9000 also I believe but I could not
get the original text. I have the LS 4000 / 5000 numbers and
those of several other scanners.
