Sourdough Starter Jar on a Floured Counter
FluxSourdough Starter Jar on a Floured Counter is a Flux.1 dev prompt for baking blog and Pinterest imagery at 4:5. Side light through the glass plus a rubber band at the original level are what make the starter look genuinely active instead of like a jar of beige paste.

Prompt
A tall straight-sided glass jar of active sourdough starter on a floured wooden counter, the starter risen to roughly double with an open bubble structure visible through the glass and a rubber band around the jar marking the original level, a wooden spoon and scattered flour beside it, a folded linen towel, morning side light from a window on the left grazing across the counter, warm kitchen tones, shallow depth of field, no labels, no text

How to use this prompt
Bakers judge a starter photo on one thing: can they see the bubble structure. Light from the side, grazing through the glass, is what reveals it — light the jar from the front and the starter goes opaque and lifeless. The rubber band is the other half. It is how every real baker marks the starting level, so it instantly communicates "risen to double" without the model having to render a written measurement, which it would garble. Keep the counter lightly floured rather than spotless; a pristine surface reads as a stock kitchen and undercuts the whole home-baking angle.
Variations to try
- Shoot it at the peak-and-collapse moment with a domed, slightly sunken top and a wetter texture
- Widen to a counter scene: banneton, dough scraper, and a scored loaf ready for the oven
