Choose Two Photos That Keep Your Characters Clear

Check the face before the file size

The face should be large enough to see both eyes, the hairline and the jaw. Even window light is useful. Dark backlighting, sunglasses and face-covering filters remove the details a model needs.

Use separate pictures

One subject per picture keeps the identity assignment clear. The pictures may be taken on different days. Avoid feeding in an existing zombie screenshot: makeup in a reference can persist into the healthy memory.

Keep the roles deliberate

The first picture is the survivor. The second is the person or pet who transforms indoors. If the role is wrong, switch the files before generating rather than expecting the story to infer your relationship.

Prepare a pet reference

For a dog or cat, show the ears, eyes, muzzle and distinctive fur. Include enough body to establish size. A large pet should be greeted at floor level rather than placed in a human-shaped leap.
