When forensic technicians first arrive to a serious crime scene, it is often late at night or into the early hours of the morning. These crimes occur and are investigated under a wide variety of lighting and environmental conditions. This creates technical challenges for the crime scene photographer who must capture these images at the highest possible level of detail under less-than-ideal conditions.

A poorly lit subject may require multiple images, including the use of flash photography from different angles at different focal lengths and exposures to capture various details.

High Dynamic Range (HDR) photography is a technique that can help overcome many of these challenges to capture a high level of image detail under a wide variety of lighting conditions.

In this article, you will learn the key principles behind HDR photography and how to apply them to everyday situations, greatly improving the image quality of your photos regardless of the type of camera you are using or the purpose of your work.
