As part of my normal post-production workflow, I frequently use Topaz DeNoise and/or Topaz Sharpen to clean up images a bit. In general, I’ve been very pleased with the products, except for the occasional small artifacts left by Sharpen. One issue that I consistently do have however is related to invoking Topaz plugins from within Photoshop (Filter->Topaz Sharpen for example), which is typically how I use these products. Sometimes they work perfectly fine and the Topaz application starts and runs as expected, but sometimes the application will not start - the little Topaz popup window shows, but nothing happens thereafter. I’ve contacted Topaz support about this and they tell me that it’s my system, not their applications. I find this hard to believe because I have a fairly robust computer, and don’t have similar problems with any other plugin. Does anyone have issues with Topaz?
