Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). 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. 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.

Adobe developed the Digital Negative format (DNG) as an open lossless RAW image file because they wanted to ensure that the DNG format would satisfy the following objectives (that they felt the RAW file format would not): digital image preservation (sometimes known as archiving), easy and/or comprehensive exploitation by software developers, in-camera use by camera manufacturers and multi-vendor interoperability.Ī DNG file contains a JPEG preview, with metadata and data for the one main image.
