Tell me again; why are you defending those LLPOF dogs?
Because you seem intent on bashing them.
Remember you can remove glare using a polarizing filter. But remember it only removes reflected light that is different in polarity. It's like looking through a pair of polarized sunglasses and still seeing everything....the filter doesn't care about the rest of the light (I agree with you there...I never said anything otherwise). Remember how a camera works. It receives wavelengths of light that are reflected from an object. Now you say the the yellow dye is sensitive to UV. So unless there was a lot of reflection off of a mirror like surface or they took a photo of the sun...then the film would hardly get much UV exposure at all. Think of it this way. If the average reflectivity of the moon is around 11% that means much of the sunlight is absorbed into the rocks and dust. And that is mostly of basaltic origin. So that means that most of the wavelengths (and yes even some IR) are absorbed. So the film picks up the light that wasn't absorbed. The lens blocks out the remaining reflected UV and you still get grey because that what color basalt IS. It wouldn't look any bluer because all you are getting is most of the visible spectrum of the scattered light which the UV would be absorbed thus not available to the camera because a camera only picks up the light reflected back.
P.S. The side lighting is the sun genius. Notice the shadows are legit. If the exposure was increased a little you get the same effect as the bright spot. You said it yourself; that there shouldn't be that much reflection from the background. But with a white suit nearby things would be a little brighter in the surrounding area.
