There are a lot of images in this week’s newsletter, so it might be easier to view on a larger screen.

[Last week](https://www.philmorton.co/how-to-prompt-ai-to-generate-images-for-concept-design/), we looked at how to prompt AI to **generate images for concept designs, storyboards and research stimulus**.

To reiterate, there are two core elements to any image prompt:

- **The scene:** *What* is being shown in the image, e.g. a woman looks at her phone on a train
- **Visual style:** *How* the image should look, e.g. a watercolour or sketch.

This week, I’ll share **a selection of visual styles that you can use in your prompts**, so you can skip the time consuming trail-and-error in finding one that works.

## Scene prompts

Below, I’ll share the same scenes with different styles. For reference, the first parts of each prompt are:

> *A wide-angle shot of a railway station.*

> *A woman in her mid-30s is standing on a railway station platform, using a smartphone.*

> *A close-up of a smartphone, which fills most of the image. It is held in one hand by an adult. The smartphone screen shows train times. The UI is a blocky concept wireframe with no detail and no text. In the background, there is a railway station platform. We only see one of the user’s hands holding the phone.*

**To replicate any image**, take the first part (above) and add the style (below).

## Black and white illustration

> *Minimalist black-and-white grayscale illustration with clean, precise linework and smooth tonal shading. Fewer sketch lines, with a flatter, more elegant aesthetic. Rendered like a concept illustration — calm, modern, and sophisticated, with natural light and subtle depth. Not cartoonish, but polished and design-focused. No text or writing in the scene.*

Note that on this one, the colours are not consistent because we haven't specified a palette.

## Isometric vector illustration

> *Isometric vector illustration at a consistent grid angle, flat colours with restrained shading, clean edges and controlled depth cues. Minimal background clutter, limited palette. No text.*

Hopefully having this selection of visual styles will give you a better starting point for creating your own images.

Have you used another style that’s worked well? Another one I should add? [Let me know on LinkedIn](https://www.linkedin.com/in/philipsamorton/?ref=philmorton.co).
