I took these pictures about a year ago, and I still enjoy looking at them. I was experimenting with an IR filter for my Nikon D50. Because the IR filter blocks almost all visible light, the shutter speed is really slow and a tripod is needed. First I set up the shot with no filter, a remote for the camera, and a secure tripod. I then previewed the picture to make sure the composition was what I wanted. Then I very carefully screwed on the IR filter and took another picture. At this point, I was shooting blind because the images are too dark to view. Because the camera has an internal filter to remove IR light, I had to process the raw image in Photoshop to correct the light levels. I like the results.
