CRW (Image)
| File extension | .crw |
| Category | Image File |
| Description | The CRW format is the Canon RAW format, which stores images produced by some of Canon's range of digital cameras. Canon uses two types of RAW file, the CRW and CR2 formats - the CRW file format is written in the Camera Image File Format (CIFF), and was the original file format used by Canon up until 2004. It has since been superceded by the CR2 format which was first used with the EOS 20D model. |

| Technical Details | The Canon CRW format has a structure that is very similar in nature to the TIFF file format specification but is easier to write to - unlink TIFF offsets are not absolute in CRW files, which means any re-writer software does not need to understand the complete file format in order to re-write the file. |

JPG (Image)
| File extension | .jpg |
| Category | Image File |
| Description | JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved. The resultant 'lossy' file means that quality can never be recovered. The JPG format is often used in digital camera memory cards. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. |

| Technical Details | JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. Compression rates of 10:1 or 20:1 yield little degradation in image quality. |
