Topaz will release B&W Effects tomorrow. It has been fun as part of their beta test group. What has been even better is they made quite a few changes based on input we submitted.
I think this is a strong entry into the black and white conversion market. There are some good features you will not find other places. I am a big fan of the brushes for local adjustment to tone, detail, smoothness, and color.
I should have some tutorials up soon and hopefully a webinar on B&W Effects in September.
