Hasselblad 3FR
The raw format for Hasselblad's legendary medium format cameras.
3FR is the proprietary raw image format used by Hasselblad cameras. It is designed to capture the immense amount of data produced by medium format sensors, which are significantly larger than full-frame sensors. 3FR files are compressed to save space on the memory card. When imported into Hasselblad's Phocus software (or other compatible editors), they are typically converted into the uncompressed FFF format for editing.
3FR files contain 16-bit sensor data. This high bit depth is crucial for medium format photography, which prioritizes color accuracy and tonal gradation above all else. The format is TIFF-based but heavily customized. It includes specific metadata for Hasselblad's lens corrections (DAC - Digital Auto Correction), which are essential for achieving the optical perfection the brand is known for.
Hasselblad introduced 3FR with their H-system digital backs. It remains the standard capture format for their H and X system cameras.
JPEG XL
The true next-generation successor designed to replace JPEG, PNG, and GIF entirely.
JPEG XL (JXL) is the most advanced image format currently in existence. Unlike WebP and AVIF, which are derived from video codecs, JPEG XL was designed from the ground up specifically for still images. This gives it unique superpowers, such as the ability to losslessly re-compress existing JPEG files to be 20% smaller without losing a single bit of data. It offers best-in-class lossless compression (beating PNG), best-in-class lossy compression (beating JPEG), and supports features needed for professional workflows like CMYK, layers, and ultra-high resolutions. However, its adoption has been slowed by political battles, most notably Google Chrome's decision to remove support in 2022, though Apple has since added full support in Safari 17.
JPEG XL uses a combination of two coding modes: VarDCT (Variable Block-size DCT) for lossy images and Modular Mode for lossless/artistic images. Its 'killer feature' is legacy JPEG transcoding: it can take the DCT coefficients from an old JPEG file and repackage them into the more efficient JXL container. This process is reversible, meaning you can convert your entire JPEG library to JXL to save 20% space, and convert them back to the exact original byte-for-byte JPEGs later if needed. It also supports 'progressive decoding' far better than any other format, allowing a high-quality preview to appear almost instantly.
The JPEG committee began the call for proposals for a next-gen standard in 2017. The final standard (ISO/IEC 18181) was published in 2021/2022, combining the best parts of Google's PIK and Cloudinary's FUIF proposals. Despite being technically superior, its rollout hit a wall when the Chrome team removed the experimental flag in late 2022, citing lack of ecosystem interest. However, Apple's adoption in 2023 (iOS 17/macOS 14) has breathed new life into the format.
