Generating an image from a simple sketch and a text prompt

This post combines prompt pages that explore the art workflow of generating images with a little control.

This AI image generation process uses the Midjouney AI feature of taking an image + text prompt to generate an image. An initial reference illustration and a simple prompt “charcoal illustration portrait of a young woman staring into the camera.” First, I created a reference image by making a simple digital sketch of a woman (on a Samsung Tablet s6). Then I uploaded the image to a Discord channel for MidJourney. Combining the Image and prompt, I got back a set of four Images that followed the image prompt well. The eyes and brows matched, the nose shading is a nice touch, and I like how the hair flows, all seem to follow the reference image well.

Prompt Terms:

<reference image> charcoal illustration portrait of a young woman staring into the camera.

Prompt Details: <reference image> (URL to the image) Charcoal (medium) Illustration (style of art) portrait (headshot framing) of a young (affects the age of subject) woman (affects both sex and maturity – not a child) staring into the camera (controls focus of subject relative to the camera)

Reference Image - digital sketch
Simple digital sketch uploaded to MidJourney. This reference image hints at composition, structure, and other image-framing information.
Resulting image from reference 4 up - charcoal images related to the prompt.

The resulting image has black bands on either side of the image, resulting from the original simple reference illustration having a different aspect ratio from the image result. Could have been avoided by ensuring your uploaded image and your desired output image have the same image aspect ratio. This is where setting an Aspect ratio can help. The use of this feature adds a –ar 2:3. (two units in wide by three units in height). By taking the reference image and the text prompt and –ar 2:3, the image result simply removed the side black bands and slightly heightened the Image composition.

Using Midjouney’s feature of taking a simple sketch and a text prompt to generate a base reference image that will be used to generate other images. This process refines and changes the final image by feeding the resulting image back into the next image generation loop.
