| Introduction | The .CR2 file format (Canon RAW version 2) is a digital photography RAW format created by Canon. "RAW" here means that this file stores information directly coming from the sensor, almost without processing. RAW files can be seen as a digital negative format, and do not contains a "ready to view" picture, like jpeg. | The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. |
| Technical details | RAW file is the best quality/size ratio storage a photograph can use to store his picture, mainly because each primary color (R, G or B) is recorded in 12 or 14bits (8bits for Jpeg), and a lossless compression is used (lossy for Jpeg). Jpeg files on the opposite are "ready to use" files, but a lot a processing is necessary to obtain such file, it is made automatically by the Camera embedded software. | The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. The Microsoft Windows file extension for this data format is '.dds'. |
