Kees, you sounded knowledgeable about ChartThrob; have you generated gum curves from ChartThrob?

Unfortunately not yet, I'm still using photoshop CS and it's only working with CS2. But it has a lot of potential I think. There is some discussion on the hybrydphoto.com forum about Charthrob. Keith Tayler who prints great fullcolor gumprints did some tests and reported about that.
What a disappointment. ;--(. I assumed you meant Keith Taylor had tested it with gum, and raced over there to see what he had to say, but it's palladium he reports on.

But I agree about the potential, whether for gum or no I can't say, but I applaud the intellect that produced it and the generosity that offered it freely to the world.

Did you also test this?

I just saw that just now, and will try it tomorrow.  Thanks,
