Howard.

I don't know if this will help, but I've just asked the list-owner to 
upload two more circular gradients to the Files > Image Processing 
folder on this site : (…)_precise_light and (…)_precise_ dark. All 
being well, they should appear there within the next couple of days.

I produced these images a few days ago after an off-list discussion 
with Jeff Randall in which it became clear to me that my original 
test file wouldn't be accurate enough for people who are able to work 
more precisely than I am (using QTR and a 51 gray patches, for 
example). The idea was that these bigger images would make it 
possible for people playing hunt-the-reversal (or similar DB&W 
pastimes) to accurately locate where a problem occurs, and enable 
them to tweak the exact value that needs adjustment. The images 
themselves include an explanation of how they operate.

Jeff was kind enough to offer to try out the images for me, but 
because of some printing problems he's having, won't be able to do so 
for a while. I'm slightly uncomfortable about uploading the images 
without them being tested on the kind of system they were intended 
for because I can't be certain that they will actually do the 
business. But it seemed to me that you might be struggling to do what 
you want with the less-accurate (original) test file, so in the end I 
decided I might as well upload them. I'll ask the list-owner to 
remove them later if they prove not to be helpful. 

Best.
