A CR2 file is a raw image file format captured by Canon digital cameras. Like most Canon formats, a CR2 file is based on TIFF specifications. Therefore, CR2 files are large, uncompressed, and offer high-quality images. Today, just a handful of programs such as UFRaw and IrfanView provide native support for CR2 files. Microsoft Windows users can also natively view CR2 files, although after installing Canon RAW Codec Software or Camera Codec Pack.
BMP, also called a bitmap image, is a raster image file format developed by Microsoft Corporation for its Windows operating system. Typically, BMP is used to save bitmap digital images in a display device and can save two-dimensional photos in monochrome and color. Although most BMP files have significant file sizes because of lack of data compression, they can be compressed losslessly via algorithms like ZIP.
