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.
WebP
Google's versatile format that does it all—transparency, animation, and superior compression.
WebP is a modern image format developed by Google specifically to speed up the web. It is a 'swiss army knife' format that combines the best features of JPEG (lossy compression), PNG (lossless compression and transparency), and GIF (animation) into a single, efficient package. WebP lossless images are typically 26% smaller than PNGs, while WebP lossy images are 25-34% smaller than comparable JPEGs. This significant size reduction helps websites load faster and consume less bandwidth, which is why it is strongly recommended by Google's PageSpeed Insights. After years of partial browser support, WebP is now universally supported across all modern browsers (Chrome, Firefox, Safari, Edge), making it the default choice for delivering optimized images on the web today.
WebP is based on the VP8 video codec (part of the WebM project). **Lossy WebP** uses predictive coding to encode an image, similar to how video keyframes are compressed. It predicts the values of pixels based on their neighbors and only encodes the difference (residual). It operates in the YUV color space. **Lossless WebP** uses advanced techniques like dedicated entropy codes for different color channels, 2D locality of backward reference distances, and a color cache of recently used colors. It operates in the RGBA color space. Uniquely, WebP supports 'lossy with transparency'—a feature JPEG lacks. This allows for transparent images that are significantly smaller than PNGs by applying lossy compression to the RGB channels while keeping the alpha channel sharp (or compressed).
Google announced WebP in September 2010 as a new open standard for lossy true-color graphics. It was derived from the VP8 video codec technology Google acquired from On2 Technologies. In 2011, Google extended the format to support lossless compression, transparency (alpha channel), and animation, effectively positioning it as a replacement for JPEG, PNG, and GIF simultaneously. Adoption was initially slow outside of the Chrome ecosystem. Firefox added support in 2019, and the final major holdout, Apple's Safari, added support in September 2020 (iOS 14 / macOS Big Sur). This universal support marked the turning point where WebP became safe to use as a primary format.
