Gone to See America October 2008 Road Trip. Eighth Annual Nikonian Photography Adventure Trip. Day 1: Yosemite National Park.
Reflections on the Merced River in Yosemite Valley. Images taken with a Nikon D3 camera and 14-24 mm f/2.8 lens (ISO 200, 14 mm, f/16, 1/30, 1/50, 1/80, 1/125, 1/200 sec). For many years I would take an exposure bracketed series of an image. For example with three images (-1 EV, 0 EV, +1 EV) or with five images (-1 1/3 EV, -2/3 EV, 0 EV, +2/3 EV, +1 1/3 EV). Then either pick the best exposure, or use a post processing program to combine two or more of the images to get a high-dynamic range (HDR) image. This allows more detail by recovering data from dark underexposed areas or blown-out overexposed areas in the image. This was especially important when dealing with digital images with 8-bits of dynamic range (i.e. jpg). The sensors in modern digital cameras are able to record images with 12 or 14 bit of dynamic range. This allows programs such as Capture One Pro to pull out more data from a single image to simulate a HDR image without needing to combine data from multiple images.
