Is there a way to set analog and digital gain?

Mon Sep 28, 2015 12:36 pm

Hello, we need to capture absolutely consistent photos using Raspberry cameras. We can set every property of Raspberry camera except analog and digital gain. We currently stop them after they settle around 1 as the documentation says but we need absolutely same values on every capture.

Is there any way to fix these values to the exact same value every capture or set them manually? The value does not matter for us, setting them both to 1 would be a solution for us for example.

You should be able to fix both gains to 1 using raspistill or raspivid by setting "-ex off". You then need to set the -awb off,-awbg and -ss for the full manual setup.
