The library of tested AI image prompts.
Hundreds of copy-paste AI image generation prompts, organised by style and use case. Every prompt was generated, graded and verified inside Postcrest before it landed on this page.
A working shot brief, written for a model that learned from real photographs.
A good AI image prompt reads like a real production brief, not a wish list. The underlying image models were trained on huge libraries of captioned photographs where the captions name the actual production details: shot type, lens, focal length, aperture, time of day, light direction, film stock, color grade. When your prompt mirrors that vocabulary, the model unlocks the latent patterns those captions sit on — sharp focal compression, real bokeh, believable highlight roll-off — instead of guessing from generic adjectives like "beautiful" or "stunning".
Every guide on this page follows the same structure: lens, light, medium, grade. Pick the one that matches what you're shooting, copy any prompt, and paste it into Postcrest. Swap the location, the wardrobe or the time of day to make it your own — the lens/light/grade scaffolding stays.
Every prompt guide, in one place.
Each guide is a curated set of copy-paste prompts for one specific subject, with the lens, lighting and grade that produced its example image.
Six rules behind every prompt on this page.
Apply these in order and you can write your own prompt for any subject you can imagine — without ever opening this library again.
- 01Lead with the camera, not the sceneOpen every prompt with shot type → lens / focal length → aperture. The first 15 words are the strongest directives, and naming a 16mm at f/11 anchors the geometry before the subject ever shows up.
- 02Direct the light, don't describe itSpecify direction and quality — raking side light, flat overcast, backlit golden hour — instead of vague adjectives. Light is what separates a snapshot from a photograph.
- 03Anchor a time of dayNaming the hour — golden hour, blue hour, polar twilight, late afternoon — loads the entire color palette the model already learned from real photographs at that moment.
- 04Name a mediumA film stock or sensor (Velvia 50, Portra 400, Cine Vision3, full-frame mirrorless) does more work than ten color adjectives. The model knows what they look like.
- 05End with the gradeClose the prompt with a color palette — cool blue grade with warm highlight, teal-and-orange, amber desert tones. This locks the final pass instead of leaving it to model defaults.
- 06Pick one emotion, one subject, one momentA clip that tries to be "joyful but melancholy and triumphant" renders mush. Direct the model the way you'd brief a real photographer: one thing at a time, said clearly.
