The price of high-quality DSLR cameras has fallen dramatically in recent years, making it easier than ever for amateur photographers to take shots that look professional. These cameras allow those with even the most rudimentary knowledge of photography to create some beautiful images. Computer programs meant to help the user edit photos have also made it easier for people to enhance the pictures they take. With the increase in sales of these software programs, high dynamic range (HDR) images have become incredibly popular.

HDR images are generally seen in the world of photography, but can also appear in other art-forms. Dynamic range is simply a term that references the levels of light a particular camera is able to process. To create an HDR photograph, the initial image must have great contrast in light levels. Good examples of photographs with HDR potential include a flash of lightning against a black, stormy sky or bright white snow on dark rocks. You will also need to understand the idea of bracketing to create an HDR image. Bracketing involves separating the original image into various sections and compressing them at a later point in the process. Bracketing is a major factor in creating the unique look of HDR images.

Although there were photographers creating HDR photographs prior to the invention of digital cameras, this technology has made the process vastly easier and more accessible. The photo-editing software on today's market has made it simpler than ever for photographers to turn standard images into beautiful HDR photos. Along with the capability to change a photo's contrast and film exposure, these software suites often come complete with HDR filters.

Many people believe that the original image must have been taken on a high-priced camera in order to create HDR photos, but this is not actually the case. Most digital cameras on the market today, including inexpensive models, have features that can make bracketing simple, thus increasing the possibility of editing the photo for an HDR appearance. For example, cameras with automatic exposure bracketing let the user capture various light levels within a single image, resulting in an HDR aesthetic even prior to the editing process.

The single most important factor in HDR photography, though, is the photo-editing software the photographer uses to manipulate the image. There are a massive number of photo-editing suites on the market, and the selection can overwhelm consumers. There are software options tailored to every photographer's individual needs and level of expertise, from software suites that are priced in the thousands to free online editing tools. It is important for shoppers to know precisely what features they need when shopping for new photo-editing software. Knowing exactly what features are necessary for their individual needs helps shoppers buy the right choice, instead of paying for a program that offers tools they will never use or comprehend.
