The first one is way cool Diane... Thumbs Up Not sure about the IR and why it is noisy... My guess is that it is reading the moisture in the air at diferent levels of intensity, or that it has something to do with reciricol failure, but I do not understand this enough yet to be sure. BTW... I do not know if it is possible, but that old shed might make some really cool shots if done from the inside out. I bet at the right time of day the lighting coming through those open slats would be spectacular. Now I am off to shoot something... I do not know what, but it is 6:35 AM in my time zone and I am going to find something to photograph.
