Raw image format

A Raw photo is a type of uncompressed image file format that’s more like a digital negative. Raws are comparable to the negatives photographers can capture with film cameras, which aren’t directly usable images. However, Raw images can still be processed into a viewable format on your laptop or desktop.

By default, digital cameras save images as JPEG. This is most likely because the JPEG file size is smaller than Raw. A single Raw image might take up 20 megabytes storage.

However, Raw photos are also much more detailed than JPEGs; and many digital cameras now enable users to save photographs in the Raw format. Each camera model has its own Raw file format, such as ARI, CRW, PXN, RAF, RWZ, SRF, DNG, RWL, RW2 and KDC. Consequently, you’ll need a codec, or driver, that supports your camera to open Raw images in Windows.
