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.
BMP is a graphic format that allows you to store bitmaps as a bitmap based on single-layer rasters. It was developed by Microsoft. She also implemented it in the Windows operating system. The BMP format (English Bitmap Picture) is used in the work of many programs, since its support is integrated into Windows and OS / 2. Files of this format can have the extensions .bmp, .dib or .rle. The BMP graphics format has often changed. From the very beginning, the image structure was built by combining small squares, that is, pixels, each of which is capable of containing data about what color depth is. It happens to be 1, 2, 4, 8, 16, 24, 32, 48 bits per pixel. The size of the final image depends on the bitness. The BMP file format still looks like a monster, since it has large sizes. After all, the image is uncompressed, which can not be said, for example, about the JPG format. Any Windows operating system has the means to open such images. The main editing tool has always been Paint - the native Microsoft program that is in every version of Windows. In BMP, images are stored in their original form, but compression algorithms can also be used. Let's say BMP provides quality support for RLE compression.
