HDRprosessering

HDR processing, short for High Dynamic Range processing, is a technique used in digital imaging to enhance the range of luminance values in an image. This allows for greater detail in both the brightest highlights and the darkest shadows, which is often difficult to capture with standard cameras due to their limited dynamic range. The process involves capturing multiple exposures of the same scene at different settings, typically one underexposed, one normally exposed, and one overexposed. These images are then merged together, with the software intelligently selecting the best-exposed parts from each to create a single image with a much wider dynamic range.

The goal of HDR processing is to produce an image that more closely resembles what the human eye can perceive. In everyday vision, we can see detail in very bright skies and dark foregrounds simultaneously. Standard photographs often have to sacrifice detail in one of these areas. HDR processing aims to bridge this gap, leading to images with a more realistic and visually striking appearance. However, over-processing can lead to an unnatural, "glowing" or "painterly" effect, which is sometimes criticized for its artificiality. The subjective nature of what constitutes a desirable HDR image means that the level of processing can vary significantly depending on the artist's intent.
