12 prompts, one for each Photoroom tool

Each one is written for ChatGPT’s image model and the mistakes it makes most.

How each prompt is built

A vague ask gets a vague picture. These read like a brief to a retoucher.

  1. Exact numbers in every prompt

    Pure #FFFFFF, the product at 85% of the frame, 2048 x 2048. ChatGPT follows a number far better than “clean” or “bright”.

  2. A product lock in every prompt

    ChatGPT redraws the whole picture on each edit, so every prompt pins the shape, colours, label text and logos.

  3. Each prompt names its own failures

    A drawn-in checkerboard, a halo round the edge, a second copy of the product, invented text: each one is ruled out by name.

Put it on pure whitefrom the prompt
Background: pure white, exactly #FFFFFF (RGB 255, 255, 255), seamless edge to edge, no gradient, no floor line, no vignette.
Placement: the whole product in frame, centred, filling about 85% of the image's longest side. Nothing cropped.
Shadow: only a faint, soft contact shadow directly under the product so it doesn't float.
Nothing else in the image: no props, no hands, no text, no watermark.
Format: square 1:1, 2048 x 2048 pixels.
