Pseudo-HDR photography, which is normally simply called HDR, means taking multiple shots at varying exposure levels of a particular subject. A special computer program will them combine images together into a single image. Post-processing is an important stage of HDR photography and involves adjustment of contrast, brightness and darkness. HDR images will have a much higher range of lighting than regular images. Such images may even seem surrealistic, because the human eye is not used to viewing photos with high tonal ranges. ImageConverter Plus has developed extended support of HDR images saved in PFM format. This will provide photographers with a superior degree of technical and artistic options.
