Step 4 - Split toning

Split Tone printing was once the domain of only a few very talented darkroom printers. However, using Photoshop we find "Split Toning"  is really very simple and a highly effective way of presenting our images. A split tone print is a black and white print that has only been partially toned or a mix of toning effects have been applied. When done correctly the effects can be really very subtle, and very attractive.

• We begin by creating the Black and White image using the "Channel Mixer" method described in Step 1, when satisfied with the tones we flatten the  image using the "Layer > Flatten Image" command.
• Make a new "Adjustment Layer" i.e. "Layer > New Adjustment layer > Color Balance"
• When the "Color Balance" dialog appears we set the "Tone Balance" for "Midtones and Shadows".
• Adjust the "Color Balance" of the midtones and shadows for the desired effect. This will be our base colour.

• Now we repeat the above exercise for the "Midtones and Highlights" but use contrasting settings.

• Next right mouse button click the "Color Balance" layer in the "Layers" palette, and select  "Blending Options".

• Now we select the "black triangle" below "This Layer:" in the "Blend If:" section of the "Layer Style" dialog.

• Move the black triangle to approximately 50

• Hold down the "Option/Alt" key on the keyboard and left mouse click the black triangle to split it.

• Now move the right half of the black triangle to about 180/200

Unfortunately the effect might not be as obvious on-screen as in print, hopefully you will see that the shadow areas retain the sepia effect, whilst the midtones take on a slight blue tone. The variations are unlimited, and certainly allow for lots of experimentation.
