Be sure to check off as you go along.
If you haven't already done so, do the Preparation described in the first section.
1) Use the Background copy layer or the composite layer (see Preparation).
The Color Picker window will open.
For sepia tones, change the values for red, green, and blue using the chart below.
You can use the values from the columns A, B, or C.
The column A color is what Photoshop Elements uses for its sepia color filter (Go to Filter > Adjustments > Photo Filter > Sepia).
If you haven't already done so, go to Color Picking.
At the top of the layers stack, look for the unlabeled Blending Mode box.
It's to the left of the Opacity box.
If you're new to blending modes, go to Blending Modes.
The Soft Light blending mode may be tried, as well.
Adjust the opacity of the layer to vary the amount of the sepia toning.
50% was used for the photograph below.
Here is the column-A-color version, again, alongside a new version using the column B color.
Instead of using a Solid Color adjustment layer, you can use a Photo Filter adjustment layer instead.
For example, you can use the Sepia filter.
Or, you can choose your own color.
Double click the colored square in the Photo Filter window to open the Color Picker.
If you haven't already done so, go to Saving Files.
The next section discusses how to mix other colors.
