Hi PhotoBob. I often use the yellow filter, or yellow-green for landscape work. In Australia we have a lot of blue/bright skies with high UV levels so the yellow filter lowers the value of the blue and makes the shots more natural looking. Brings out the clouds too. I almost always shoot with a yellow filter when using these old cameras from my collection as they have inherently low contrast compared to modern optics. As for scanning, I really don't know, but they are much easier to print. Cheers, Tony
