Directed Optical Artifacts

About this prompt pack

This pack teaches you to prompt optical artifacts as local, physical events instead of asking for a vague cinematic look. The 8 square examples move from single-source halation to split-diopter focus, wet glass, directional motion trails, and a three-effect product hero. The controls transfer to portraits, product shots, sports campaigns, and editorial photography because each prompt names the source, boundary, protected zone, and failure mode.

What you'll learn

• Controlled halation — Halation gets one source, one color, and a narrow boundary. The protected blacks and sharp subject stop the requested bloom from turning into haze.
• Diffusion without mush — A filter strength plus protected midtones separates diffusion from soft focus. Material cues keep the glass convincing while only the hard highlights bloom.
• Local prism echo — The refraction has an address, a shape, and a maximum footprint. Naming the untouched center prevents the prism effect from swallowing the portrait.
• Two focus planes — Both sharp zones get concrete micro-detail, while the middle is explicitly soft. The garage pillar gives the optical transition somewhere believable to disappear.
• Diffraction as grid — Counts turn a lens effect into composition. Six sources, six stars, and lane-line repetition make the optics part of the grid instead of decoration.
• Water as lens — The pane has physical rules, and the face gets a protected clear channel. That combination makes the droplets act like lenses without losing the portrait.
• Flash at the end — Direction is the control variable. The final body is sharp, earlier positions fade behind it, and the empty left half gives the trails room to explain the exposure.
• Three effects, three jobs — The final prompt assigns halation, diffraction, and refraction to three separate coordinates. The product stays neutral because every effect also gets a boundary.
