I notice you chose -1 white balance.
Is this done to counter the effects of the head lights pointing at you?
I am not familiar with the Canon camera you are using, is this the result of shooting
in automatic, aperature or shutter speed preference? Are you using the 400ISO to force
greater depth of field and shutter speed? I'm not understanding what you're setting to get the color and sharpness you're getting. In my Sony world, I must choose between portrait, landscape and twilight. I can shoot automatic or aperature or shutter and I can also choose ISO rating. So I'm trying to make the necessary conversion in my mind of what you are doing. Thanks for any help you can provide.
