Yes, thanks, I'm aware of Krita and am up-to-date with it, but the main problem with it is it doesn't have recordable-replayable Actions like Photoshop. Krita might be used to load the render stack to a saved PSD. As might the free and faster Paint.net (?). But it could not then juggle the order of the imported layers, rename them to meaningful names, knock out white from line-art, run a Photoshop filter on a color layer, and so on. Most people will want a Photoshop PSD and Actions in a format they know how to tweak and edit, plus easy access to Photoshop plugins for filtering some of the layers. Paint.net does have a plugin to record Actions, but it's not ideal. Same with Photoline's limited Actions capabilities. I'm not sure about the other budget software. Last time I looked Photoshop Elements didn't do Actions.

I'd never heard of OpenCV, so thanks for that. Seems to be a Library for the computer vision people?

As for Poser 12, hopefully the final will be out any day now, and then we'll see all the new features added since the early access version. The PIP sounds very interesting. It can't just be a static reference image able to be stuck in the viewport, surely, from the sound of it? I imagine a new full-Viewport PIP Window which "lays" on top of Poser's native viewport, and whatever this special Window "sees" sitting beneath it is "piped out" to Photoshop and then "back in again" in real-time? Thus giving near real-time visual filters for the Viewport in Poser, powered by Photoshop? Kind of like how some software already does a round-trip of an image to another software, but in near-realtime. But I guess that could only work either with the OpenGL or with a very fast graphics card / workstation running a near real-time 3Delight viewport.
