Re: [ATM] Paper Towel Reflectometry? :)



Hi James,

Perhaps the bump in the red is due to averaging in the incandescently lit frames. I believe incandescent lighting is lacking in blues. Did you try averaging only the ones from the flash, and compare to only the ones from the sun, and from the incandescent? Might be worth a try.
