This is one of my favorite image effects. The sepia-tone look will give you an image similar to an aged red/brown photograph. Daguerrotypes from the 1800's is a good example of the effect you can get
when you try sepia-tone.
Step 1 is to choose a photograph. It can be color or black and white.
The next step is to change the image "mode" to grayscale.. This is accomplised by selecting grayscale in the "mode" drop down menu. After you have coverted to grayscale, you next need to convert it again to "CMYK." You do this the same way as you selected grayscale. Converting to CMYK will allow you to adjust the color balance to get the sepia effect.
Once you have converted to CMYK, select the "color balance" option under the "adjust" drop down menu. Once you are in color balance make sure the "preserve luminosity" box is checked.
You are now ready to change the color of your image.
Start in "shadows" by selecting that option. Adjust the color level slider bars to 30 in cyan, 5 in magenta, and -45 in yellow
Next, select "midtones" and adjust the slider bars to 68 in cyan, -10 in magenta, and -10 in yellow.
The last change will be in "highlights." Select 33 in cyan, 0 in magenta, and -18 in yellow.
Your results will look something like the photo on the left..
One final note: . If you are going to use your photo on the Web, make
sure you convert it from CMYK to RGB or web browsers will have a hard time
reading the image.
