HDR (High Dynamic Range) images have been around for a while, but have seen a surge in popularity in the last few years, due in part to the increased availability of HDR imaging software like Photomatix. These types of software go some way to taking the pain out of the creation process, by aligning and combining images, leaving the photographer to tweak various settings to achieve the desired result.
But before you start tweaking, you’ll need some images to play with: Series of images created from one image in Photoshop, final tone mapped HDR image at the end.
An Introduction to HDR
Images taken with most cameras today can only capture a limited range of brightness without under-exposing or over-exposing the image. HDR imaging looks to increase this range by combining the dynamic range (brightness values from shadows to highlights) from a series of images of the same scene into one HDR image. You’ll probably find that the best candidate for an HDR image will contain a large dynamic range ie shadows and highlights, and a scene with a similar spread of brightness i.e. all shadows, or all highlights, will tend not to work so well as an HDR image.
