pyunraw is a CPython implementation of dcraw, the command line application which allows you to decode the raw image produced by some digital cameras.
pyunraw embed dcraw himself, it is written with CPython for Python 3 and produce, after compilation, a Python module.
pyunraw was initially developed for Oqapy, a photografic workflow application.
A minimal example of use:
>>> from pyunraw import PyUnraw
>>> raw = PyUnraw("_DSC2850.NEF")
>>> # Check if this format is supported
>>> raw.is_raw
True
>>> # Check properties of the file
>>> for k, v in raw.data.items():
... print(' %-20s%s' %(k, v))
