Even though the location says Tunnel View in Yosemite, this photograph is not the typical composition most visitors or photogs see since the view is 90 degrees to the right shooting up the hillside. This photo was one of the last ones I shot on the late night of April 18th and the morning of 19th, after an evening on shooting moonbows at Yosemite Falls.
The bright center section of clouds is actually being lit up by the full moon with the moonbow just off to the upper right. Unlike the focusing issues I had throughout the evening in the dark since my lenses don’t have an infinity symbol on the focus ring, focusing here was much easier. All I had to do was focus on any area that had both tree silhouette and bright clouds. The 4 second exposure captures the movement of the clouds while the tripod keeps everything relatively vibration free during the long exposure.
EXIF data: Nikon D50, patterned metering mode, 150mm, ISO 400, 4 sec, f/5.6
