Explanation of HDR (High Dynamic Range) Photography

Video Transcript

"My name is Brandon Sarkis on behalf of Expert Village. Today I'm going to to give you an overview and introduction to HDR, or High Dynamic Range photography. High Dynamic Range imaging - it's a set of techniques that allows a greater dynamic range of exposures 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 shadows. It was originally developed for use with purely CGI, or computer generated images. Later methods were developed to produce an HDR image from a set of photographs taken within a range of exposures. With the rising popularity of digital cameras and easy to use desktop software, the term HDR is now popularly used to refer to the process of tone-mapping, together with the bracketed exposures of normal images, given the end result a high, often exaggerated dynamic range. Have an image from a side range. Tone mapping is also used to display or see images on devices with a low dynamic range, such as a computer screen. The other thing is is that when you go to, when you're actually using or editing in HDR, most of them output in formats that are much higher than a computer screen can render, so you typically have to downgrade them down to a JPEG, or downgrade them down to a TIF when you're done. Which is kind of funny, but what are you going to do? You can, however, if you're sending them off for prints you can send them off in full size formats. They'll get fully exposed prints back. So, there we go."
