| Description | PEF is a digital image format used in Pentax digital cameras such as the K3, K5, K10 and K20. Pentax cameras capture photos with unprocessed image data and information on the conditions when the photos were taken. The PEF format is based on the TIFF format - PEF uses a non-standard file header and includes additional image tags and encrypts some of the tagged data. |

| Technical Details | RAW files are an intermediate format. They contain unmodified sensor data from the digital camera, packaged with metadata about the shot as well as a JPEG preview (for quick viewing). In Pentax-proprietary PEF files the data is both losslessly compressed and of a higher bit depth than that of JPEG. PEF files are 12-bit as a standard, however on the K-5, K-5IIs, and K-3 models they are full 14-bit RAW files. |

| 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. |
