What is “Dynamic Range” The Dynamic Range of an image is the “ratio between the brightest and darkest parts of the scene.”
An exampleof a lowdynamic range.
What is HDR Photography? “HDR is an acronym for High Dynamic Range. It is a post-processing task of taking either one image or a series of images, combining them, and adjusting the contrast ratios to do things that are virtually impossible with a single aperture and shutter speed.”(from Trey Ratcliff, http://www.stuckincustoms.com/hdr/)
What is HDR Photography? Humans eyes can see a much wider dynamic range than a single DSLR image can capture. HDR photography combines the “highs” and “lows” of multiple exposures into a single image.
For me, it is a way to create a photograph that better captures the highlights (bright whites) and shadows (the dark blacks) that might get lost when taking a photo.
How to shoot for it…1. Mount your camera on a tripod2. Use manual or Aperture Priority mode. Take at
least three exposures: good exposure, under-exposed, and over-exposed. Number of exposures varies based on how wide the dynamic range of your scene is.
“I recommend using a camera that has autobracketing. Autobracketing is the ability for your camera to take at least 3 pictures right after one another, each at different exposures. Sometimes it’s called “Exposure Bracketing”. If you have a DSLR camera, then you probably already have this ability.”(www.stuckincustoms.com)
How to process it…
Use “HDR” software such as:• Photomatix Pro• Nik HDR Efex Pro• Photoshop 5
