IR in the desert
I took my new Canon 70D out for a little day hike in the desert and decided to see how it does with an infrared filter (a Hoya R72). Here are some samples:
This is a white light image showing the Moon rising over the hills nearby. This exposure was made with my 75-300mm zoom at 75mm focal length with an exposure of 1/250 seconds at f/11, ISO 200.
This is the same composition with the Hoya R72 IR filter in place. The exposure was 2 seconds at f/4, ISO 200. I converted the original to B&W with the GIMP and a simple desaturate followed by a little curve stretching.
This is the original frame before desaturating the image. The exposure was 2 seconds at f/2.8, ISO 400 with my 50mm f/1.8 lens on my 70D.
This is the same frame, desaturated and stretched a little with the curves tool in the GIMP.
This is the white light version of the above. The exposure was 1/350 seconds at f/8, ISO 400 with my 50mm f/1.8 lens.
