....I am not a fan of overly dark skies and I appreciate atmospheric distance. I stopped using a yellow filter with TMax films. Seemed like a yellow filter with Tri-X, Pan-X, etc corrected the film so that it recorded the sky pretty much like our (my) eyes see it. TMax does that without filters, so the yellow has more effect than I like now. And I have development control of each negative, so I can control the sky values that way. Over-all, I usually do not have sky in my images, but in Death Valley, one often does not have a lot of choice! Below is about as dark as I go! Spring, Death Valley. Platinum/palladium print, 8x10
