*.RAW ('''Raw Image Format''') is an image file generated by digital cameras such as some Panasonic, Leica, and Casio cameras; contains uncompressed, raw image data; can be adjusted for exposure and white balance in software after saving the image to the computer; used for storing unaltered image data as captured by a digital camera's CCD. RAW files may also be created by image generation software, although this is not as common. <ref>[http://www.fileinfo.com/extension/raw RAW]. FileInfo.com.

*.BMP ('''Bitmap Image File''') is an uncompressed raster image comprised of a rectangular grid of pixels; contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color. BMP files may contain different levels of color depths per pixel, depending on the number of bits per pixel specified in the file header. They may also be stored using a grayscale color scheme. <ref>[http://www.fileinfo.com/extension/bmp BMP]. FileInfo.com.
