beaufortfrancois has just created a new issue for 
https://github.com/w3c/mediacapture-image:

== mediaSettingsRange should return step ==
It should be very easy for developers to specify the `step` value in 
`<input type="range">` HTML elements.
Please provide this information when available.

For info, I can get it with a Logitech C920:

```sh
