what does that mean ?
What I meant was that as the the initial set of nodes and the image processing pipeline were created, the idea of comping in linear and working in float rather than 8/16 bit ints was first and foremost. When I was at ESC and toxik was just developing we had quite a few discussions with the discreet guys about how working in float linear was different from int linear or log. From a software development point of view there are different choices and assumptions you make with regard to how you spend your finite amount of development time, like doing SSE optimization on x86 chips if you know your main focus is floating point processing rather than int. Also, with floating point images being effectively unbounded (as opposed to 8/16 int where you’ve got a hard min and max value any pixel can take), you can’t really implement color operations as LUTs accurately. So there are design choices that are affected by the decision to focus on linear encoding and float pixel values. Finally, one of the first color correction tools toxik got was the photolab tool which does exposure changes in stops and printer lights, something that really works well with linearly encoded HDR images but implementation-wise depends on the encoding. A mult is a mult regardless of what the image encoding is, but “up a stop” depends on how you represent your image data.
Just so you guys know we will be providing a bunch of Toxik training stuff in a month or so.

That’ll be awesome Mike. I’ve been using Toxik for close to a month now, and think the interface/workflow is great. Though, it’s missing some pretty important tools at this stage. Autodesk does have some pretty good free video training on their website, but any additional stuff would be great.
Hi Everyone, im new in FXguide, node based compositing and toxik,
its nice i find a toxik forum in here.i like toxik… especially the Gate UI, keying tools and color correction tools…
regards!
there is a guy in australia named warren bones that is a Toxik specialist for Autodesk. i’ll let him know that there was someone interested in this forum.

wow thanks VisualZ…. and its a nice website you got there
