High - Dynamic - Range Imaging
High-dynamic-range imaging (HDRI or HDR) is the method which ensures the capturing of a better dynamic range between the lightest and darkest areas of an image. They show a precise range of intensity levels in scenery images.
The effect is captured though taking several images of the same view with different exposure levels from direct sunlight to faint starlight. Cameras with limited contrast ranges often lose detail in bright or dark areas of a picture depending on the choice of
exposure levels.
Using Photoshop to stitch together the multiple images with different exposure levels helps to produce a picture that is representative in both dark and bright areas. It can also be used to exaggerate contrast for artistic effect. The effect can also be
completed through computer rendering.
HDR images can also be acquired using:
Special image sensors, like oversampled binary image sensor
Tone mapping methods, which reduce overall contrast to facilitate display of HDR images
To create my HDR image I had to change the exposures of my initial photograph so that I had an image with exposure minus 2 and plus 2.
I then Opened the HDR tool (File>Automate>Merge to HDR...), and loaded all three of my photographs in the exposure sequence.
I lastly used a histogram to add final adjustments to my image giving it my desired look.
