Color choice is what separates a flat photo edit from a convincing movie poster. This tutorial walks through how to apply triadic color harmony to a single street photograph, using yellow as the dominant tone with controlled accents of blue and red to create visual tension and draw the eye to the subject.

Practical Tips
These techniques from the tutorial can be applied to almost any portrait or street photo you want to turn into a poster.
- Use Camera Raw's guided geometry lines to straighten symmetrical compositions before any color work — small alignment issues become obvious at poster scale.
- When shifting reds toward yellow with Hue/Saturation, mask the adjustment off skin tones immediately to avoid an unnatural, jaundiced look.
- Reinforce your accent colors on specific elements — push the subject's clothing toward blue with Curves by pulling down the red channel and boosting the blue, creating contrast against a warm background.
- Add gradient layers above and below the composition (foreground to transparent) to darken the edges and create a natural backdrop for legible title text.
- When setting title lettering, keep line spacing slightly wider than word spacing — this prevents the layout from feeling cramped and follows basic typographic proportion rules.
