The Starter Climbed Past Yesterday's Rubber Band
Bubbles ring upward in the glass jar, and the band sits where it was yesterday.
✍️ The rubber band is the narrative point of the whole image: you see at a glance how much the starter has risen. f/11 on medium format keeps the bubble rings sharp top to bottom. A time-trace detail like this carries more information than any adjective.

Frame: 1:1 square. Subject: a tall, straight-sided glass jar full of bubbling sourdough starter, standing at the middle of a pale oak board and spanning the central two thirds of the frame height. The camera is level with it, looking from the side. Up the glass wall, bubbles form rings, with finer bubbles stacked in each band above the previous one. One rubber band loops the jar at the height where the starter peaked yesterday, far below its domed top today. In front of the jar a wooden spoon lies across the board, flour dusting its bowl.
Colors: cream starter behind clear glass, warm oak, white flour. The jar has no label and no lettering.
How it was shot: a real photograph, commercial still-life genre, taken with a medium-format digital sensor and a 100mm lens at f/11, which keeps everything deeply sharp from edge to edge, with ultrafine grain. One large overhead softbox, slightly front-left, sends even directional light downward, giving clean specular accents on glossy finishes and short contact shading right under each form. The finish is bright and neutral in colour, tight in contrast, true to material sheen. A single tall softbox reflection runs down the left side of the glass.
