I realized after yesterday's post that comparisons between the various tints might be difficult. Each image was handled individually. So any consistancy between the images for contrast, resolution, and tint handling might be invalid.
Here's my second try. The first image uses Ken Lee's "Bronze Quadtone".
The next image uses my sampled chocolate. This is the one I think is a little too magenta. But I'm willing to reconsider this position.
The last image uses my sampled second chocolate tone, with yellow added to the mid-range and very slight yellow added to the highlights.
I'm not yet sure, but it feels as if Ken's quadtone tint has more depth than the two chocolates I sampled.
