Photographer #233: Michael Light

Michael Light, 1963, USA, focuses on aerial photography. He looks at settled and unsettled areas across the USA and explores themes of mapping, human impact on land and environmental issues. He uses a handheld large format camera to make his photographs. He flies the aeroplane himself. He combines the images of each serie into a  narrative sequence and hand-makes mammoth artist's books out of them. Besides his own photography he makes books. Full Moon contains images from NASA's Apollo photographic archive and 100 Suns has images of visible nuclear testing in New Mexico. The following images come from the series White Ranch/Table Mountain/Rooney Valley, Salt River/Deadman Wash/Paradise Valley and Bingham Mine/Garfield Stack.

An Introduction to High Dynamic Range Imaging (HDR)

HDR, or High Dynamic Range Imaging seems to be all the rage these days. HDRI is described by Wikipedia as:


In image processing, computer graphics and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures
(the range of values 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 shadows. (from Wikipedia)

More accurately however, the images that are commonly seen and referred to as HDR or HDRI images are tone-mapped.

Tone mapping is a technique used in image processing and computer graphics to map a set of colours to another; often to approximate the appearance of high dynamic range images in media with a more limited dynamic range. Print-outs, CRT or LCD monitors, and projectors all have a limited dynamic range which is inadequate to reproduce the full range of light intensities present in natural scenes. Essentially, tone mapping addresses the problem of strong contrast reduction from the scene values (radiance) to the displayable range while preserving the image details and color appearance important to appreciate the original scene content.
