Test Images should include;
very dark areas that have detail; areas of high modulation to check
sharpness and registration
skin tones of nominal values and transitions to shadow to check banding and
ability to render pastels
Areas of near white to check minimum tone lay down
Grey scale and Gretag Macbeth color checker/DC checker
Saturated colours especially red and yellow
Textures including gloss, mix such as metallic fabric, natural; wood plants
As you can see these should be separate images not everything in one. Also
avoid the trap of scans that no prepress bureau would do which is the case
of the ISO photos. They have areas much too large at 0% and other test
images at Lab values down to about 1-4 L. Some test images also have skin
tones of 0% complimentary colour, which is good for glowing babies but a
good scannerist would be shot for this.
Oh if you have a test file please leave it in a space appropriate for high
gamut conversion. The so called GettyOne re-tagged HDM tiffrgb is good for
non-knowing users of rgb but for anyone on this list will be much too small
small of a space to consider for any serious test purposes.
Feel free to contact me if you have further questions.
