LRGB?

I get what the RGB is but what is the "L"? I think it is Lumanance but exactly what is that? Real begginer here still shopping.

Hi Marty,

luminance is correct. That means a frame taken with no filter hence containing all the colors.

The idea behind it is to shoot a very good L frame. This frame later will be respnsible for sharpness and contrast.

The RGB frames then can be exposed much less or even at lower resolution.
