File Types

    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.

    FIle TypeDescriptionRecommendation
    RAWThis 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
    TIFFStands 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.
    DNGStands 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 cameraUse only if you have special needs.
    PNGStands 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.
    GIFStands for Graphics Interchange Format, this is a very old Standard. It is limited to 256 colors.Do not use
    BMPStands 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
    JPEGIs 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
