AI Film Stock Emulation
Naming a film stock is the fastest way to set a whole colour palette in one word. But most people only know 'Portra'. This guide holds one portrait across 14 film stocks, so you can see exactly what each film's colour science does, warm Kodak skin tones, punchy Fuji saturation, gritty black-and-white, neon-haloed CineStill night. Copy a prompt, add the stock name to anything, and you have the look. It goes deeper than the film-stock section of the DSLR guide. Works across Midjourney, GPT Image, Flux and Nano Banana.
Works in: Midjourney, GPT Image, Flux, Nano Banana, Stable Diffusion.
How to use this skill
When the user asks for an image prompt in this style, compose one using the formulas and vocabulary below. Fill each slot with a concrete choice, then return the finished prompt. Prefer naming a real camera/lens, a light, and a colour or film treatment, which is what makes the output read as a real photograph rather than an AI render.
Formulas
The film-stock formula
[your scene], shot on [film stock], [one or two of its traits]
Add a trait or two to commit the model: 'shot on Kodak Portra 400, warm skin tones, fine grain'. The stock name does most of the work; the traits sharpen it.
