One of the latest developments materinty that took photography to a whole new level today is the HDR.
What is HDR Photography
High Dynamic Range Imaging or simply known as HDR photography is a type of photography that involves the use of a set of methods in photography and imaging, to get the greater dynamic range between the lightest and darkest arrange of an image than standard digital imaging methods or photographic methods. Images in HDR can capture images in more accurate intensity found in real-life scenes, whether it’s under direct sunlight or even in faint starlight, and is often shot through plurality of pictures in different exposure of the same subject.
In layman’s term, HDR images show more dynamic range as compared to those images taken by an ordinary digital camera and make high-quality photographs. HDR is a type of photography method that provides higher dynamic range right from the imaging process.
Cameras with no HDR capabilities capture photos using one exposure level and in a limited contrast range. As a result, images are lacking of details both in bright and/or dark areas of the picture, depending on how the camera is set (low or high exposure setting).
HDR addresses this loss taking details in multiple pictures using different exposure levels and joining them all together to come up with one photo that shows both the bright and dark areas of the subject. HDR method usually captures three or more photographs taken in different exposures to make a more beautiful and dramatic final image.
The term HDR is also used to refer images derived from HDR imaging in such a way that it exaggerates the contrast of a subject for the sake of artistic effect.
HDR is actually a relatively new concept, and many people mistake this as more colorful and an unrealistic artistic type of photography. The use of HDR technology is to increase the dynamic range, capture clearer photographs, and overcome all the restrictions there is in standard and ordinary camera.
The Theory Behind HDR Photography
There are actually two theories behind HDR photography, and as the technology develops, so as the discipline. However, if one has to take this genre seriously, then he or she must first understand the concepts and theories that make up this type of photography.
The most basic of all HDR photography theories is to capture multiple shots of the subject at varying levels of exposure. The camera’s special program will then combine these images into one single image.
The second theory is with the use of RAW processing software. Photographers need to make various levels of exposure of an image. A lot of compact points-and-shoot digital cameras and mid and high-end Digital SLR cameras in the today allow shots of RAW images. A RAW file is an image captured using the camera’s sensor; it’s unprocessed, and thus, it doesn’t contain color information yet. Photographers then need to maneuver this file, adjust lighting, white balance, and of course, exposure.
