Scans
Posternity offers a specialized Processing Mode for scans and photos of text. It can extract the extremely fine, gritty details you can find in scans or photos of signatures and official stamps.
Step-by-step tutorial
In the tutorial below we remove the background from a photo of a signature. You can follow along with this written tutorial, or try out this image for yourself in the Editor.

Clipping Magic immediately analyzes your image and automatically produces a result:

Scan mode works a little differently from the other modes. It operates by analyzing the area marked in yellow to figure out what's background and what's foreground in that zone. Anything that's not marked with yellow defaults to background.
This means that you want to make sure that all parts of your signature, stamp, or other foreground are well covered by yellow marks. If the automatic marks came up short, then use the hair tool to add any missing marks.
While normally not necessary, if the foreground appears too faded out or transparent, you can zoom far in and add selective green marks to bring those spots up to 100% opacity.
