How do I generate AI models with non-traditional features like tattoos or piercings?
3 min read
Quick Answer
Describe the trait in plain English on the AI person in the shot. In Nightjar, that means picking or building a Fashion Model (Nightjar's reusable AI-person ingredient) and adding a short note like "a sleeve tattoo on the left arm" or "a septum piercing" in the Custom Directions field. To add a trait to an image you already have, open it in the Edit tab and write a one-line instruction such as "Add a small floral tattoo to the right forearm." For repeat use across a campaign, build a custom Fashion Model from 1 to 5 reference photos that already show the look.
Why airbrushed models can read as fake
Hyper-polished AI faces tend to read as synthetic to younger audiences. Texture, asymmetry, and individuality (visible pores, freckles, body ink, piercings, gap teeth, vitiligo) are what make a person look photographed instead of generated, and AI tools default to a generic, retouched face unless you describe those traits explicitly.
How to add these features
Method A: describe the trait at generation time
Nightjar's image-creation flow uses a reusable AI person called a Fashion Model. You can pick one from the 80+ pre-built roster, or build a custom Fashion Model from 1 to 5 reference photos that already show the tattoos, piercings, or features you want, with name, age range, and gender as metadata.
Once a Fashion Model is selected, add the trait in Custom Directions, the short text field for refinements layered on top of the selected ingredients. For example: "a streetwear shoot of a woman with a neck tattoo, urban lighting." Custom Directions is the right place for trait-level direction because it does not replace the underlying Fashion Model, Photography Style, or Composition.
For tattoo placement specifically, be explicit about the body part and side ("left forearm, inner wrist") and the style ("traditional American color, bold lines"). Generic phrases like "a tattoo" land less reliably than a placed, named one.
Method B: edit an existing image
If the photo already exists, open it in the Edit tab, the multi-image editing surface where each image you add becomes a referenceable input.
- Add the image to the editor board (Nightjar calls each stored image an Asset).
- Reference it inline as
@image1and write a plain-English instruction, for example: "Add a traditional floral tattoo to the right forearm of @image1."
The result blends the tattoo into the skin tone and fades it slightly so it reads as healed rather than as a sticker on top.
Method C: save the look for reuse
If the same tattooed or pierced model needs to recur across SKUs, save the full setup as a Recipe. A Recipe is a Nightjar feature that stores the chosen Fashion Model, Photography Style, Composition, background, Custom Directions, and output settings, so the next product can use the same person and the same look without rebuilding the brief. To produce a small set of cohesive variants from one strong shot, use Photoshoot, the Workflow that expands one input Asset into four AI-directed variants that feel like one session.
