I looked at them again. It’s highly unlikely that the spill of all four lights has the same brightness. The XM-L2 light should have a darker spill than the other becuase it produces less lumens (<=2000).
So your buddy probably had exposure an/or iso set to auto.
I understand what you are saying. He probably has it on one of those settings.
I was specifically talking about the clarity and quality of the photos on here and CPF. The photos themselves are sharper/clearer on CPF. I am not sure how that set up works with the different websites.
