File Format Glossary
All the diffrent File Formats and their use
Term | Definition |
---|---|
BMP | a compression-free format that preserves image data but creates large file sizes |
Cineon | used in the Kodak Cineon Digital Film System, which transfers images originated on film to the Cineon format and back to film with no loss of image quality |
DCS (Desktop Color Separations) | a version of the standard EPS format that lets you save color separations of CMYK images |
DICOM | the most common standard for receiving medical scans |
DNG | the Adobe Digital Negative format, meant to be an industry-wide standard format for raw image data |
EPS (Encapsulated PostScript) | a standard format used to transfer PostScript artwork between applications; unless it is imported as a Smart Object, Photoshop rasterizes vector graphics on opening |
GIF | a “lossless” compression format with a limited color palette; and is better suited to illustrations, as it supports animation and background transparency |
JPEG | a common standard for compressing photographic files; image data is lost each time you edit and save in JPEG format (“lossy” compression format) |
Large Document Format (PSB) | preserves layers and most plug-in features for files up to Photoshop’s limit of 300,000 pixels in width or height |
OpenEXR | a film format with high color fidelity and a high dynamic range suitable for use in motion picture production |
PDF (Portable Document Format) | created by Adobe, the Portable Document Format allows readers to view accurate electronic versions of documents even if they don’t have the creation application |
Photoshop Raw | a file format for transferring raw-data images between applications and computer platforms; not to be confused with Camera Raw |
PNG | a newer “lossless” compression format; supports millions of colors, multiple bit depths (8, 24, 32), 24- and 32-bit alpha channels, and gradated transparency but with larger file sizes than JPEG; not all browsers support PNG format |
PSD (Photoshop Document) | native Photoshop format, which we recommend for most image editing tasks |
Targa | designed for systems using the Truevision video board; commonly supported by MS-DOS color applications |
TIFF (Tagged Image File Format) | a standard format for exchanging files across applications, computers, and scanners; creates large files with the option of “lossless” compression; can be resaved without quality loss |
