Are there any Pythonic solutions to reading and processing RAW images. Even if it's simply accessing a raw photo file (eg. cr2 or dng) and then outputting it as a jpeg.
Ideally a dcraw bindings for python, but anything else that can accomplish the came would be sufficient as well.

Python is an excellent choice for these types of image processing tasks due to its growing popularity as a scientific programming language and the free availability of many state-of-the-art image processing tools in its ecosystem.
After that, install rawpy using: git clone https://github.com/letmaik/rawpy cd rawpy pip install numpy cython pip install . The LibRaw library is installed in /usr/local/lib (if installed manually) and apparently this folder is not searched for libraries by default in some Linux distributions.
A while ago I wrote a libraw/dcraw wrapper called rawpy. It is quite easy to use:
import rawpy import imageio raw = rawpy.imread('image.nef') rgb = raw.postprocess() imageio.imsave('default.tiff', rgb) It works natively with numpy arrays and supports a lot of options, including direct access to the unprocessed Bayer data.

ImageMagick supports most RAW formats and provides Python bindings.
As for dcraw bindings for Python: dcraw is written in C, so you can access it through ctypes module.
