Its been along time since my last post.
I am working in the CCamera API.
I have been trying to control the viewfinder's
brightness, e.g., the automatic fix that the viewfinder
adds to the view captured, so that it is displayed better.
For example, when it is dark, then a redish effect added.
When it is very bright, a darkenning effect is added.
I need to control all those effects.
Not in the pricture that Iam about to capture,
but in the viewfinder's feeding frames themselves.
