175 What is HDR
What is HDR
It seems like every time we go to capture an image we have to
choose between the highlights and the shadows. Traditionally with
film you would expose for the shadows and then develop for the
highlights. With Digital we must expose for the highlights and
bring up the shadows. The problem is images are limited by the
extreme ends and they don't match what we had seen at the time of
capture. This is where High Dynamic Range (HDR) comes in. HDR is a
technique to create an image with details from the deep shadows
through the bright highlights. True HDR is a set of multiple
captures of the same scene at different exposures and using
software to composite elements from each image and overlaying
separate elements to create one photograph containing highly
detailed information from 0-255 in all shadows and all highlights
as long as that information was available from any of the original
images. There are many HDR-like photos being made from singular RAW
files where the highlights are brought down, the shadows are pushed
up, and the whites and blacks move similar directions. I find those
types of "HDR" images are not true to the form of the multi photo
HDR's. I have two images here one is from a single RAW file (the
fake HDR-like edit) and then another made up from 11 RAW
images at varying exposures. Can you tell which HDR is which?
