The new updates for the varius Image Magicks have introduced an optional effect, called Sepia. However, those of us who have tried this effect have found that it isn't a true brownish sepia. In fact, it's pretty yellow! So I've discovered a technique that will give a sepia-toned effect.
Start with either a color or a black and white image. The colored image I used is:
For a colored image: click on Colormap. Uncheck Dither, check gray. Click on Quantize.
Output and save or put the temporary url into your Find box. Or use a B&W image. Here is the gray version of the above:
Back up to the gray or using the B&W image, click on Colormap again, uncheck Dither, check Posterize, click on Quantize. Below is what the Posterized version looks like:
Paint: colors are peachpuff, peachpuf2, peachpuff3, peachpuff4 - from light to dark. Blur @ 5000; Replace instead of floodfill; Color. Paint each of the posterized areas that you want to look sepia, using the peachpuffs as desired.
Composite: Put the gray or B&W image url into the composite box. Set gravity @ Southeast. Composite 4 times, using the filters below, in that order:
1) Screen
2) HardLight
3) SoftLight
4) Luminize
Annotate - color I used is #988988 (the color of this background)
Output as Truecolor (image type)
You might try some different comps for the first one instead of Screen. I'd found a comp recently for the Old Geezer (see below) that had enhanced the peachpuff color, but it wasn't Saturate - that just wiped out the color. I'd like to get a darker "sepia" like I did with the Old Geezer, but for now, Screen as 1st comp will do.
The annotate color is one to play around with, too. Use #988988 as the lightest color, then go to #766766, #544544, #322322 (the color of the text) - or back up a bit if the last two are too dark.
Here are the results of playing with these colors listed above:

Sepia Result
For the Smiling Lady, I used only two comps: first, SoftLight; second, Luminize. Luminize seems to smooth out and blend the various colors. So I think you can play around with the comps: Screen, HardLight and SoftLight - maybe you'll need only one of them. But always finish with Luminize.
Other sepia-type color hex codes to try: dark: #654321 - medium: #987654 - light: #fedcba - also try the ones in between the two dark and light extremes.
