Digital SLR cameras tend to have better quality sensors than compact digital cameras and the large high-end camera backs have features such as built-in cooling mechanisms that help them produce the very best in image capture quality. Right now there are certainly a lot of photographers who are interested in exploring what can be done using high dynamic range image editing. Basically, high dynamic range image editing requires a whole new approach to the way image editing programs like Photoshop process the high dynamic range image data. The light contrast ratio from the darkest point in a scene to the brightest will vary from subject to subject, but in nearly every case it will certainly exceed the dynamic range of even the best digital cameras. Therefore, when capturing a high dynamic range image the objective is to make sure the people capture the entire contrast range in a scene from dark to light.
