What a watermark can and cannot do

A watermark deters casual copying and makes attribution travel with the image when it gets reposted. That is genuinely useful, and it is the realistic goal. What it does not do is prevent theft, a corner watermark can be cropped out in seconds, and content-aware fill in Photoshop or any of the numerous automated watermark removers will clear a semi-transparent overlay with reasonable results.

The trade-off is visibility against intrusiveness. A tiled watermark across the whole image is far harder to remove cleanly, because reconstructing the image underneath requires inpainting every affected region rather than cropping one corner. It is also considerably more intrusive to look at. Photographers often use a light tiled watermark on preview images and supply clean files on purchase, which gets both properties.

Two things worth knowing. Watermarks are not a substitute for copyright registration, in a dispute, registration and the original raw file with its EXIF metadata carry far more weight than a visible mark. And be aware that many platforms strip EXIF data on upload, so if metadata is part of your provenance strategy, keep the originals yourself rather than relying on what the platform preserves.
