A few pictures of an icicle taken with my new Pentax k-x. Nothing spectacular, as I'm still getting the feel for the new camera.

My first attempts at using a Hoya R72 infrared filter with a Canon Powershot A540 and a Pentax k-x. All photos from the k-x were taken with the 18-55mm kit lens. I noticed after uploading them that the ISO was set to 800. I forgot to change that back to 200 before taking these pictures. Next time, I guess.
