To meet the needs of average consumers, DpsDave uses JPEG files with slight compression.
This is the universally accepted file type specially designed for images, and is compatible with all computers, and works with all photo viewing and editing programs.
Below is the table of common file types that are associated with image files.
|RAW||This is an image class, not a file type. it refers to files that have all the original image data. The most popular file types in this class are TIFF and DNG|
|TIFF||Stands for Tagged Image files. No compression, no loss of fidelity. These are big files, used by professionals, and this is a rather old files type. It’s actually intended for raster (Thanks Galen!) files.||Use only if you have special needs.|
|DNG||Stands For Digital Negative Graphics and based on the TIFF format, a DNG file contains the data (raw images data and metadata) needed to render an image without needing additional knowledge of the characteristics of the camera||Use only if you have special needs.|
|PNG||Stands for Portable Network Graphics, this is a very old
standard. It uses compression and had color depth greater
than human perception. However, file size and image quality
are inferior to JPEG
|Do not use.|
|GIF||Stands for Graphics Interchange Format, this is a very old Standard. It is limited to 256 colors.||Do not use|
|BMP||Stands for Device Independent Bitmap, this type has
adequate color depth and resolution for images, but is inferior
to the RAW class of the types while file size is similar to the RAW file types.
|Not intended for photographers|
|JPEG||Is an acronym for the Joint Photographic Experts Group, who
invented this format. Introduced in 1992, this standard is
continuously updated, with the latest revision published in 2008. It uses compression with good image characteristics.
|Use this with 80% compression|
