In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene 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. This method was developed to produce a high dynamic range image from a set of photographs taken with a range of exposures. With the rising popularity of digital cameras and easy-to-use desktop software, the term HDR is now popularly used to refer to this process. This composite technique is different from (and may be of lesser or greater quality than) the production of an image from a single exposure of a sensor that has a native high dynamic range. Tone mapping is also used to display HDR images on devices with a low native dynamic range, such as a computer screen.

I hope a cropped photo is alright ... if not, let me know and I'll pick another.
I took this photo within weeks of getting my Sigma f/2.8 105mm EX DG macro lens. I was still reeling from the price tag, and still trying to learn It was one of a series I'd taken. I won't tell you how many bees I had buzzing around me. Several actually turned out. The entire photo is pretty nice, but the detail was lost, so I ended up cropping for the subject & the light. ![]() EXIF Info: Photo taken: 20 March 2008 Exposure: 1/200 Aperture: f/8 Focal Length: 105mm ISO: 100 Exposure Bias: -7/10 Flash: No Flash White Balance: Manual
