Today, I was to work with a steamed up surface like a mirror or a windshield. The only problem with that is it steams up the camera lens, too! After running the hot water in the bathroom for a little bit, I went and grabbed my camera. At first, I wondered why I couldn't see anything. Then, I had to wipe the lens off and take the picture before it steamed up again. When it dries, I'll probably clean the mirror. It wouldn't be very nice to leave it marked up like that. Have a great night!
