This video on Vimeo is absolutely amazing! It is a combination of day and night shots that were taken in Yosemite National Park. This next video is also a collection of shots from Arizona and Utah. Both of these videos are absolutely worth the time to watch them. The second video is by a guy named Dustin Farrell and he has some great tutorials on shooting and post processing.
