3 ways to change a black and white photo to sepia.
There are many way to change a photo’s tint using photoshop. I have made this short tutorial to show you how to change a photo from black and white to sepia using three different methods, each with similar results but with subtle differences.
We can use this image as a test image.

Method 1. Change your photo to RGB mode . Select from the top menus – image/adjustments/photo-filter.

You will get a colour box pop up. Choose a sepia colour.

Choose a fairly dark one

and then use the slider to increase the density.

Final result.

Method 2 This method using ”colour balance”. From the menus select image/adjustments/colour balance

Change the sliders with the radio button “shadows” selected so that you dial in around 20 red and 20 yellow.

Then do the same with the “midtones” but around 15 red and 15 yellow. You can tweak these setting to your own preferences.

Here is the final result. This method does not alter the whites in the highlights.

Method 3 Using a colour fill layer. Select from the menus, layer/new fill layer/solid colour

Then select “colour” in the blending mode box.

Select a nice sepia colour

and you are done!

I hope this helps everyone and just choose a method which suits you best, if it were my choice I would go with method 2
