What is HDR?
HDR means High Dynamic Range.
For those who aren’t so acquainted with this high-tech shutterbug lingo, dynamic range is basically just the difference between the lightest light and darkest dark you can capture in a photo
Often, the scene’s range of brightness and darkness is too large to record all the details we want with our gear.
Even great photographers with amazing cameras can only very rarely grab the scene exactly as they saw it.
High dynamic range technique allows you to reveal detail and contrast that are missing from normal images and is generally used to deal with high contrast subjects.
This helps to achieve the same task in the final photograph that the human eye can accomplish on the scene.
