Make it yours

Fill in the inputs. Your prompt updates as you type.

Before you paste

Attach one clear portrait you own or have permission to transform in the image platform. Use a consistent adult reference, with the face unobstructed.

Your prompt

Using my uploaded portrait as the identity reference, generate one square 2×2 photographic contact sheet on textured darkroom paper with the same recognizable adult person in all four panels.
Top left: {{era_1_style}}
Top right: {{era_2_style}}
Bottom left: {{era_3_style}}
Bottom right: {{era_4_style}}
Preserve recognizable bone structure, eye shape, apparent age and skin tone as closely as possible. Change wardrobe, environment, light and photographic treatment, rather than identity. Keep natural skin texture and avoid plastic smoothing.
Use even white film borders and small frame numbers 1–4; no additional captions, logos or watermarks. Keep each face unobstructed and centered within its panel. This is a fictional era transformation, not historical evidence.
