Marketplace requirements
Articles about Amazon, eBay and Etsy image rules reflect the published guidance I could find when writing, and my own experience of what passes. They are not official. Check the platform’s current help pages before relying on any figure.
Colour accuracy
A white generated here is numerically exact. How it looks depends on your display and its calibration. Use the calibration patches, and for colour-critical work a hardware colorimeter.
Using screens as backdrops
Placing products on a tablet or monitor is at your own risk. Protect the glass and keep liquids away.
Bench tools
The pixel, burn-in and refresh tests are visual aids, not hardware diagnostics.
Advertising and links
Ads and sponsored links are labelled. A link is not an endorsement unless I say I use the product.
