[libcamera-devel] [PATCH v2 0/2] Digital gain control

[David Plowman]

Hi everyone

Here (after much talking ourselves in circles!) is a second version of
the digital gain control. I've taken Jacopo's text for the control
description, and added a second patch that makes use of the control in
the Raspberry Pi IPAs to add the digital gain to the metadata.

This second patch doesn't really tell you very much. In our libcamera
version of raspistill (still image capture app) there will be a line
like this:

    iso *= metadata.get<float>(controls::DigitalGain);

and that's about it!

Best regards
David
