What is the deafult primary channel?

[ashalota]

If I have a 4 band image and leave the "primary channel" option set to default, which bands are used in the image alignment?

If I have a 3 band image with the default, does it use all 3, or just a certain one for the image alignment?

Is it possible to set only a specific 2/3/+ bands for image alignment? I know I can set it to use 1 specific one, but I wanted to make sure that I'm not losing the option to include 3 bands if I have a multi-band image.

Just checking if there is any answer on this. About to start work with an NIR band as well and want to know if I should create a 3-band image first (so I can use all 3 bands), or if there is a way to use 3 bands (even if I have a 4 band image)

Hello,

I have the same question. RGBI Images and the question if in the default-Setting all 4 channels will be used.

Thanks for your answer,
