DPX (Digital Picture Exchange)
The industry standard for digital intermediate and visual effects work in film.
Digital Picture Exchange (DPX) is a raster image format used primarily in the motion picture industry for visual effects (VFX) and Digital Intermediate (DI) work. It is an ANSI/SMPTE standard (SMPTE 268M-2003) designed to represent the density of film scans without loss of quality. Unlike consumer formats, DPX is usually uncompressed and stores color information in a 'logarithmic' (Log) format to preserve the full dynamic range of motion picture film. A single second of 4K movie footage in DPX format can consume enormous amounts of storage (hundreds of megabytes), making it strictly a production format, not one for distribution.
A DPX file starts with a 'Generic Image Header' (magic number: SDPX) containing core details like file size and image orientation. This is followed by 'Industry Specific Headers' for Motion Picture or Television data (timecodes, frame rates). Finally, the 'Image Data' block contains the raw pixel values. DPX supports a wide variety of bit depths, but 10-bit Log RGB is the most common industry standard. It packs these 10-bit values tightly into 32-bit words (10+10+10+2 padding) for efficient processing. The logarithmic encoding mimics the human eye's response to light and the physical characteristics of film stock.
DPX is the direct successor to Kodak's Cineon (.cin) format, which was developed in the early 1990s for the first digital film scanners. As the industry moved towards digital workflows, SMPTE (Society of Motion Picture and Television Engineers) standardized Cineon into DPX to ensure compatibility between different vendors' scanners, printers, and software.
TIFF (Tagged Image File Format)
The venerable standard for print, scanning, and archival.
TIFF (Tagged Image File Format) is one of the oldest and most robust image formats still in use. Created in 1986 by Aldus (later acquired by Adobe), it was designed to be a universal standard for desktop publishing and scanning. TIFF is a container format, meaning it can hold almost any kind of image data—compressed or uncompressed, RGB or CMYK, 8-bit or 32-bit. This flexibility makes it the go-to choice for the printing industry, professional photographers, and archivists who need a format that preserves maximum quality and metadata without the compatibility headaches of proprietary RAW files.
A TIFF file is built around 'tags' that describe the image data. This allows it to support a vast array of features, including multiple pages (used for faxes and document scans), multiple layers (like a PSD file), and various color spaces like Lab and CMYK that are essential for printing. TIFF supports multiple compression schemes. The most common are LZW (lossless) and ZIP (lossless), but it can also hold JPEG (lossy) data. Uncompressed TIFFs are standard for archival because they are future-proof and require no decoding algorithm that might become obsolete.
TIFF was the first format to bring high-resolution, grayscale, and later color images to the desktop publishing revolution of the late 80s. While JPEG took over the web and consumer photography, TIFF remained the king of the pre-press and scanning world. It hasn't changed much since Revision 6.0 in 1992, which is a testament to its robust design.
