Note: “auratum” word sounds peculiar but it is to refer to the golden colouration. Sometimes it is found in yellow colour too.

When you can’t move the background away move the subject away from background. Background will get lighted if close or if shutter is too low or if aperture is too big. I have used three flash lights with very low aperture and high shutter and then edited a bit.
