CR2 is a graphic file format developed by the manufacturer of camcorders and cameras Canon. This means that all images made by the equipment of this manufacturer are saved by default in CR2 format (short name from Canon Raw Image File). One of the most attractive properties of images of the specified format is their high quality, even if the file is being edited (color balance, contrast, brightness change). Data for the CR2 format image is obtained directly from the matrix. Among the main drawbacks of the format are the large file size, as well as poor compatibility with other software products.
DCR is a graphic format for bitmap images. DCR, or Kodak RAW Image File, is a Kodak format RAW file. Files of this type are usually used in digital SLR cameras in order to take photographs and at the same time not to compress or adjust the color. The format was developed by Kodak, whose specialization is in the manufacture of photographic equipment. Kodak RAW Image File, like other graphic RAW formats, is primarily designed to store digital images in an uncompressed and unprocessed form. In this case, they can be edited more accurately. They are stored on a computer so that later the photos can be edited more accurately compared to JPEG images. After processing on the computer, the DCR file can be converted to any popular format. Say in JPEG. DCR images are capable of storing data without compression. They do not include default colors and color correction. And this is inherent in a JPEG image. The main advantage in using this RAW format is that you can have better image quality if digital post-processing is performed. To make the details more visible, and the shapes more defined, you need to reduce noise and better balance the white color.
