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 2000 VM Uncompressed
A single-component test format for JPEG 2000 verification.
PGX is an extremely simple, uncompressed raster format created specifically for the development and testing of the JPEG 2000 standard (ISO 15444). It is defined in the JPEG 2000 Verification Model (VM). Its purpose is to store a single component (channel) of an image with potentially high bit depth and signed/unsigned values, without the complexity of a full image container.
A PGX file represents one image channel (grayscale). It starts with a minimalist text header identifying the endianness (`LMS` or `Big`), the sign (`+`/`-`), the bit depth, and dimensions. The raw pixel data follows immediately. It is effectively a raw dump of a single image plane.
Developed by the JPEG committee during the creation of JPEG 2000. It allowed researchers to test wavelet compression algorithms on raw data without worrying about file headers or color transforms.
