m3f

List metadata of Hasselblad raw files.

Install / Build

The installation consists of a single executable, m3f. Download the version for your OS from releases, and unzip it in a folder that's in your path.

Building from source requires a Common Lisp implementation. m3f is tested with and known to work with SBCL and CCL, but should also work with other implementations.

Usage

m3f is a command-line application. By default, it displays the metadata in a format as close as possible to what the "Capture Info" tab in Phocus shows. For example:

$ m3f test/resources/raw1.3FR
        Device: CFV 100C/907X
       Created: 2025:01:16 15:46:52
    Dimensions: 8742x11656, crop mode 65:24 (XPan): 4302x11656
          Lens: XCD 28P, serial number: 8QHI15094 (year: 2024)
     Converter: ?
     Extension: ?
           HTS: ?
           ISO: 400
       Shutter: 1/160
      Aperture: f/4.0
   Light Meter: Centre W
 Exposure Mode: Aperture
    Focus Mode: Single
 Serial Number: JT63001117
GPS Coordinate: ?
   Orientation: Rotate 90 CW
       Quality: 16 bit
 White Balance: Daylight
    Drive Mode: Single Shot

The lines up to and including "GPS Coordinate" should be identical to the information shown by Phocus, except that m3f will sometimes display more details, such as the lens serial number.

A "?" means that I have not yet been able to decode the information. I need help with that; see the wiki.

Running m3f without arguments will display detailed usage information.
