Light and Shadow
I'm spoiled by Pentax's SMC coatings, I don't hesitate to shoot into the sun at all. That filter has caused some major flare here. Still the major flare element has fallen into a dark region and adds some interest to the shot. I honestly can't remember if I could see it through the viewfinder. I do remember wondering how it would look though.
Pentax 24mm f2.8 set to f/16 @ 1/125 with a 25A red filter.
