The abbreviation HDR (sometimes seen as HDRI) stands for High Dynamic Range (Imaging or Imager) and refers to the capture of digital images with a greater dynamic range of luminosity.
HDR images are suitable for situations with very high dynamic range such as welding when very high brightness is created due to the welding arc, which makes it hard to detect the weld or the weld object. Even with varnishes or other glossy surfaces HDR images with increased dynamic range may be required due to reflections and high lights.
IDS offers a variety of camera models that are able to capture HDR images. In this TechTip various HDR methods are explained and compared.
