i just recently began using my infrared filter with the K20D i purchased not to long ago. I had been using the filter with the K110d and loved the results. however- i'm getting black and white photos with this infrared filter on the K20d, i'm wondering if i'm setting the white balance wrong? Because with the 110d the pictures would usually come out purpleish. Also i'm getting a kind of blue soft line going across some of the images. anyone got any advice?
