DNG (Digital Negative)
The universal raw format designed to stand the test of time.
DNG (Digital Negative) is an open, royalty-free raw image format developed by Adobe. It was created to solve a major problem in digital photography: every camera manufacturer uses their own proprietary raw format (CR3, NEF, ARW, etc.), and when a new camera comes out, old software can't read its files. DNG acts as a universal container for raw sensor data. It preserves all the original image information—just like a proprietary raw file—but wraps it in a standardized, publicly documented structure. This ensures that your photos will remain readable by software decades from now, even if the camera manufacturer goes out of business.
DNG is based on the TIFF/EP standard. It stores the raw sensor data (Bayer pattern or X-Trans) along with metadata defining how that data should be interpreted (color matrices, white balance, linearization tables). Uniquely, DNG also supports 'Linear DNG' (partially processed/demosaiced data) and 'Lossy DNG' (which applies JPEG-like compression to raw data, significantly reducing file size while retaining raw editing flexibility).
Adobe launched DNG in 2004. While initially met with skepticism, it has been adopted natively by several manufacturers (Leica, Pentax, Hasselblad, and most smartphones including iPhone and Pixel) and is the standard format for mobile raw photography.
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.
