Subject: Creating a Sepia Tone Filter

---

I have been working on trying to creat a sepia tone filter. I have used
many suggestions, but none have worked unfortunetly.

//New Red = R*.393 + G*.769 + B*.189
//New Green = R*.349 + G*.686 + B*.168
//New Blue = R*.272 + G*.534 + B*.131

//gr = (0.30 red) + (0.59 green) + (0.11 blue)
//r2 = gr * 0.44; add tint
//g2 = gr * 0.27;
//b2 = gr * 0.15;

none of the two worked. If anyone had any feed back that would be great.
