In this format, you can save images that are shot on Sony (Minolta) cameras and some digital SLR cameras. MRW images are stored in uncompressed RAW form, and they contain more detail than compressed images. This format allows you to edit the white balance, exposure, brightness, and other elements losslessly.
This format is used for storing bitmap images with improved levels of color and brightness performance. It combines exposures to record darker tones in the shadows or detail in the lighter areas of a given photo. HDR is able to combine multiple images with different levels of light distribution. It is used to create rich images.
