This was just brought up in a thread about this sort of filter here: http://www.thephotoforum.com/forum/showthread.php?t=25328 I know that Ferny quoted there from the B&W site saying that you can use UV filters on film and digital cameras to get rid of the blue haze sometimes created being in very clean air, high altitude, or near the ocean. Here's my question: Does the UV filter work on the digital cameras? I thought the reason the blue haze appeared was because of the UV rays affecting the film in a funny way. Like it mixed up UV light with visible light and made it become visible by having it activate the blue in the negatives. Does it really make your digital photos better? Or does the sensor not respond to UV or am I completely on the wrong track with my understanding of why the blueness appears.
