What does this format store?+
3FR is a native Hasselblad raw capture format. It stores image data for subsequent photographic processing with camera information, rather than only a finished JPEG. It is associated with compatible Hasselblad cameras and backs; processing should follow the actual model and its supported raw workflow, not a generic assumption about medium-format files.
How does compression affect quality?+
Hasselblad’s H6D guide distinguishes 3FR captures from FFF files produced in its processing workflow. That relationship is not just a suffix rename. Sensor precision and processing behaviour depend on the model and software; avoid assigning one universal sample depth to every 3FR.
Are 3FR and FFF the same file?+
Hasselblad documents 3FR as capture and FFF as a related processing representation. Keep their roles separate and check the software workflow; changing the extension does not perform the conversion.
What should I check before opening the file?+
Check the exact camera model and recording mode in the processor’s support list. Raw support is model-specific, even when the extension is recognised. Viewing an embedded JPEG preview does not prove the sensor data has been decoded.
What changes when I export to another format?+
Raw-to-image export develops the data: white balance, colour mapping and tone become part of the pixels. Grayscale, palette and SDR targets can discard additional information. Keep the original; converting a rendered image back into a raw container cannot reconstruct the capture.
When is this format useful?+
Use the raw original for repeated photographic development when exposure interpretation and colour decisions need to remain flexible. Export JPEG for an opaque delivery image or a suitable high-precision raster for further editing. Those exports bake in processing choices and cannot recreate the original sensor data, calibration or all vendor metadata.
