Recipe
The examples above were generated with Nano Banana Pro and Seedream 4.5. The recipes below are written for GPT Image and Flux, so treat the settings as a starting point rather than the exact run.
A description in plain sentences. This is the version to start with, and it works on any current image model. Settings below are the ones we used on GPT Image; treat them as a starting point.
This recipe describes a treatment rather than a thing. Put your own subject in and it is added to the end of the prompt.
A single everyday object drawn entirely in blue ballpoint pen on cheap cream paper: all tone built from thousands of small overlapping loops and hatch strokes, the pen skipping in places and pooling ink in others, paper showing through wherever the pressure eased. Nothing else in the frame, no ground line, no background, no colour other than the blue of the pen. Obsessive and hand made. Subject: a worn trainer with loose laces.
