HDR Images – combining several images into 1 image
I recently have been experimenting with HDR or High Dynamic Range images. In simple terms HDR images are a combination of images put together into 1 image to more accurately represent the range of intensity levels found in a real scene. Ever taken an image in the middle of the day where the subject you are shooting comes out perfect but the sky is just to over exposed? If you took another image with the exposure set for the sky with HDR techniques you could merge the 2 images to get 1 image where both the sky and your subject are correctly exposed. On most cameras you can set your camera to take 3 images at 3 different exposure settings (normal, higher and lower) automatically.
On a canon 7d simply go to - menu – 2nd menu – expo.com./AEB and turn the front dial to set the 2 other exposures at how ever many stops you want them…
