John, thanks for the post. I have been following this "hue error" thread from the beginning and was waiting for a chance to try some of the suggestions. Your experience sounded so much like mine, I had to try your method. I have also had very good results from Profiler RGB, with the exception of the "purple blues". I picked two of my photos that had given me a lot of trouble; one, a covered bridge with bright blue sky and blue shadows in the snow, and the other a waterfall taken in open shade, with very blue water and shadows. I selected Blue in the HSL panel and dialed in 15 on the cyan side. I then made small 3x5 inch images of before and after and printed them simultaneosly on Epson HWM (1160, Generations 4) using a profile that gave very good colours except for the blues. The difference was remarkable - well worth further exploration. I loved your last line about print making being a craft and an art. I just wrote to David Miller of ColorVision this morning, musing about how many of us (myself included) have become a bit spoiled with all this new technology. We expect it should work perfectly all the time, with little or no input from us (after all, we paid enough for it!). I printed Cibachromes for 25 years, and just recently I am starting to get inkjet prints that are better in almost every respect. No dust spots, either <g>.
