HDR Images + How to create them

Monday, November 06, 2006

So what do you think about this photos ? Beautiful isn't it ? First time when I saw them I didn't know exactly what they are, pictures or drawings.After some research on the web I've found that what they truly are, HDR images.You might ask yourself "What the hell is HDR" ? So to spare your time I'll show you there what HDR images are.

HDRI = High Dynamic Range Imaging

High dynamic range imaging (HDRI) is a set of techniques that allow a far greater dynamic range of exposures (i.e a large difference between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to the deepest shadows.

HDRI was originally developed for use with purely computer-generated images. Later, methods were developed to produce a HDR image from a set of photos taken with a range of exposures. With the rising popularity of digital cameras and easy to use desktop software, many amateur photographers have used HDRI methods to create photos of scenes with a high dynamic range. However, HDRI has many other applications and "HDRI" should not be mistaken for just this use.

If you want to learn how to create HDRI images I've have some tutorials for you : Tutorial 1, Tutorial 2, Tutorial 3.
