HDR Imagery
13th November 2006

HDR Imagery:- Some of my favourite images reworked using HDR Imaging software. HDR Imagery consists of "blending & Tone Mapping" a series of images shot at varying exposures. The Camera - unlike the human eye - will expose an image based on the brightest part/the majority of the frame, which on bright days can result in a perfectly exposed subject and a bleached out shy (normally the case resulting in lack of sky colour or cloud detail) or if the sky is the prominent factor in the image, a perfectly exposed sky (resulting an a dark subject matter image). The Way HDR works is to blend an image 1 or two stops under exposed (dark subject - correct sky) with a 1 or 2 stops over exposed (good shadow detail - no sky detail/bleached out) with a third image that the camera judges to be exposed correctly (the camera's best guess). After the three images are combined and a tone mapping matrix is applied the results can be a very realistic to the eye image, or depending on how the matrix is applied an almost "oil painting" like effect. Hours of good clean fun!!
