Hasselblad RAW Image
The gold standard for medium format digital photography, delivering unmatched color accuracy and dynamic range.
FFF (Hasselblad Flexible File Format) is the proprietary raw image format used by Hasselblad's legendary medium format digital cameras and scanners. Unlike consumer raw formats, FFF files are designed to hold the immense amount of data captured by large medium format sensors—often exceeding 100 megapixels—with zero compression artifacts. An FFF file is typically the result of importing a native '.3FR' capture into Hasselblad's Phocus software. During this import, the file is wrapped with specific calibration data unique to that exact camera and lens combination, as well as Hasselblad's Natural Colour Solution (HNCS) profile. This ensures that the image provides the most accurate starting point for professional retouching.
The FFF format is a container for uncompressed or losslessly compressed raw sensor data. It supports 16-bit color depth per channel, allowing for a theoretical 281 trillion colors, which is essential for capturing subtle tonal gradations in skin tones and landscapes. Technically, an FFF file contains the raw Bayer pattern data from the sensor, along with extensive metadata including exposure settings, GPS data, and copyright info. Crucially, it also embeds 'opcode' lists—instructions for lens correction (distortion, chromatic aberration, vignetting) that are applied non-destructively by the raw converter. The format is optimized for the Hasselblad Phocus workflow but is widely supported by third-party professional imaging software.
Hasselblad introduced the FFF format alongside its transition to digital imaging. As the company moved from film backs to fully integrated digital cameras like the H-system and later the X-system, they needed a format capable of handling the massive data rates and quality requirements of medium format photography. The format has evolved to support increasing resolutions, from the early 16MP backs to modern 100MP+ sensors. It remains a cornerstone of the high-end commercial photography industry, synonymous with the 'Hasselblad Look'—a distinct rendering of color and contrast that many photographers prize.
PNG-24 (24-bit RGB)
The standard for opaque, true-color lossless images on the web.
PNG-24 is the standard version of the PNG format for opaque, full-color images. It supports 24-bit color depth, which allows for over 16 million distinct colors (True Color)—the same color range as a standard JPEG. Unlike JPEG, however, PNG-24 uses lossless compression. This means it preserves every single pixel exactly as it was created, with absolutely no blurring or artifacts. This makes PNG-24 the ideal choice for complex graphics, screenshots, and detailed diagrams where quality is paramount and transparency is not needed. Note that while 'PNG-24' is often used to refer to any true-color PNG, strictly speaking, it refers to the RGB variant without an alpha channel. If you need transparency, you are technically using PNG-32 (RGB + Alpha).
A PNG-24 image consists of three color channels: Red, Green, and Blue. Each channel uses 8 bits of data per pixel, resulting in 24 bits total (8+8+8). This allows for 256 levels of intensity for each primary color, combining to produce 16,777,216 possible colors. Because it lacks an alpha channel, every pixel in a PNG-24 file is fully opaque. While the PNG specification allows for a 'tRNS' chunk to define a single specific color as transparent (similar to GIF), this is rarely used in modern web design in favor of the full alpha transparency found in PNG-32.
PNG-24 was part of the original PNG 1.0 specification released in 1996. It was designed as a direct, patent-free competitor to JPEG for lossless image storage. While JPEG won the war for photographs due to its superior compression ratios, PNG-24 became the standard for screenshots, diagrams, and digital art where preserving exact pixel values was more important than file size.
