What is HDR Photography? "The intention of HDR imagingis to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows." --Wikipedia  |

High Dynamic Range Photographs (HDR} are produced from a series of exposures of the same subject, from very over-exposed to very under-exposed. The images capture detail in all highlights and shadows, closely mimicing the way the human eye sees. The result is that you can see the very fine details in both the highlights and shadows without one taking precedence at the sacrifice of the other. |

| The HDR photo on left captures details and colors in both highlights and shadows. The most pleasing "normal" digital photo of the same scene gives some detail in the rock, but the sky loses its color and texture and colors are muted. HDR doesn't work for everything, but it is a very useful tool. |
