I just upgraded to Cineform Neo HD in order to use First Light. OMG is this great! I have lots of questions about how to use it but this whole real time, no strain on the CPU, instant color change and film looks thing is just too cool for words. I did a quick search to see if anyone was discussing this before I made this post and I see nothing. If you haven't looked at this you just have to check it out!
