Step-by-step: Color Balance, Levels and Threshold
1 Color Balance is useful in creating extra contrast between colours. Move the sliders between cyan/red, magenta/ green and yellow/blue to adjust which colours are most prominent. Use the dropdown menu to switch between adjusting the shadows, mid-tones and highlights. 2 Levels enable you to emphasise the lights, darks and contrast in your image. Moving the left slider in the top window adjusts your dark value range, and moving the right slider does the same thing with whites. The middle slider adjusts dark/light contrast in general. 3 A strong silhouette is a key part of good composition, and Threshold makes it possible to simplify everything down to basic black and white shapes. If your values are reading well, then you should still be able to tell what’s going on. If not, I suggest rearranging your values.
