Information about HDR and PNG file formats

Name HDR PNG
Full name HDR, High Dynamic Range Image File PNG - Portable Network Graphics
File extension .hdr .png
MIME type image/png
Developed by HDRsoft PNG Development Group
Type of format Raster image lossless bitmap image format
Description Files that Have the HDR extension are raster image files saved in a the High Dynamic Range format. This format is most commonly used for digital photos. Images saved as HDR images are used for enhancing images and photos with regard to color and brightness. Washed out areas, shadows and other dynamics can be easily fixed in HDR images. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.
Technical details The pixel values of a HDR file can cover the whole tonal spectrum that is present in the real world. HDR images are able to display the largest possible range of pixel values. Thus, direct light and sunshine as well as extreme shadows can be captured with a life-like portrayal of colors. HDR images can be created either by merging different photographs in a specific way, by using special image sensors, or via computer rendering. PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.
