Prompt
A 16:9 image split vertically down the middle into two halves of the same home office desk. The left half is chaotic: tangled cables, leaning stacks of paper, coffee rings and a crooked lamp under dull flat lighting. The right half is the identical desk perfectly organized: a closed laptop, one small plant, aligned notebooks and warm clean daylight. A crisp vertical seam divides the two moods, upper corners of both halves kept simple and uncluttered, high contrast youtube before and after thumbnail composition, no text anywhere in the image.

How to use this prompt
Flux is the right model for this format because it can actually hold "the identical desk" across both halves — most models drift the furniture, so keep "two halves of the same home office desk" verbatim. The lighting contrast ("dull flat lighting" versus "warm clean daylight") does more storytelling than the clutter itself; change only the objects and the halves read as two random desks. "A crisp vertical seam" matters because Flux otherwise blends the transition into an unusable smear down the middle. Keep the corners clause — thumbnails in this format live or die on whether your BEFORE and AFTER labels have somewhere clean to sit.
Variations to try
- Kitchen version — "two halves of the same small kitchen counter, dirty dishes and spills on the left, cleared counter with a fruit bowl on the right"
- Garden version — "two halves of the same backyard, overgrown weeds and a sagging fence on the left, mown lawn and string lights on the right"
