We’re probably all familiar with the classic techniques of photographic toning from seeing various examples of Sepia toned images, but for years analog photographers have been experimenting with chemical toners to create various processing effects. One such technique is to split tone a print to create a dark blue and copper coloured image with a dark dejected mood. In this tutorial we’ll look at using Photoshop to replicate this classic technique in digital form, using Color Balance adjustments to achieve the same range of blue and yellow tones.
Typical sepia toning of a photograph gives the image that classic orange/brown appearance, resulting in a much warmer atmosphere than the basic black and white alternative. Split toning on the other hand produces much more stark effects by creating unusual colour combinations. One popular technique is the bleaching of highlights with sepia, followed by the treating of the shadows with selenium to give a harsh mix of blue and yellow tones. The result is a cold and dejected mood which works great with photographs of abandoned ruins or urban exploration. Here’s an example of this effect applied to a photo from a friend’s exploration of Chernobyl. See more of his great shots of Dark Pripyat.
Split toning in Photoshop
Sepia/Selenium split toning effects work best with photographs that feature some kind of desolate scene in order for the dark blues to give the image a gloomy atmosphere. My buddy Ric kindly supplied one of his Dark Pripyat shots as the base for this tutorial.
The whole purpose of photographic toning was to inject some colour into a basic black and white image before the colour film was available. Therefore the first step we need to take in Photoshop is to convert our modern digital image to monochrome. The best way to do this without losing the image’s contrast is to click the “New adjustment layer” icon at the bottom of the Layers palette and select Black & White.
Add another Adjustment Layer, this time selecting Color Balance. There’s a few different ways to adjust the toning of your image, such as Gradient Maps or Curves adjustments on each channel, but the Color Balance option make it easy by allowing you to adjust the amounts of specified colours such as Yellow or Cyan.
Make sure the Preserve Luminosity checkbox is selected, then change the Tone option to Shadows. Increase the Cyans and Blues in the shadows to create the Selenium effect by moving the sliders to 30 Cyan and 40 Blue.
Next, change the Tone selection to Highlights, then adjust the sliders to represent the sepia tones in the highlights. This means moving the sliders to 25 Red and 35 Yellow.
The image has already been given the dark split toning effect, but final adjustments of the overall tone can be made using the Midtones sliders. Adding just an extra +10 Red helps warm up the sepia tones a little, or conversely adding more blue will enhance the coldness of the effect.
The split toning effect is complete, but I always like to sharpen up images with a quick High Pass filter. Press CMD+A to Select All, then go to Edit > Copy Merged. Paste a copy of the image at the top of the layer stack.
Go to Filter > Other > High Pass then adjust the slider until the details are subtly appearing from the grey background.
Change the blending mode of the high pass layer to Linear Light then reduce the opacity to around 30% to tone down the sharpening effect until it looks more natural.
The final sepia/selenium split toning effect replaces all the tones of the image with blues and yellows and creates a dark and gloomy mood which enhances this particular subject of an abandoned city.
