A simple Python 3.6 script that converts RAW files from some Sony cameras (tested with Sony - Alpha a6300 Mirrorless Camera) to JPG files. The RAW files should have the ARW file extension. This project borrowed key ideas from Python Image Converter. If all else fails, you should use Sony's Imaging Edge. Imaging Edge is a great software and will likely give you superior conversion quality, however, the conversion is rather slow (images are NOT converted in parallel). In any case, DO NOT throw away your RAW files just because you have converted them to JPG.
To use arwjpg, you should create a Conda environment. Clone this repository and change directory cd into it. Then type in the following.
conda env create -f environment.yml
conda activate arwjpgIf you need to destroy the environment, type in the following.
conda remove --name arwjpg --allTo use the arwjpg.py Python script, make sure you activate the arwjpg Conda environment as mentioned above. Then type in the following.
python arwjpg.py -s [source_dir] -t [target_dir]Note that
source_diris a directory containingARW(RAW) files.target_diris the directory whichJPG(JPEG) files will be placed.
By default, ALL your CPUs will be used to convert ARW files to JPG files! An example on Windows is given as follows.
python arwjpg.py -s C:/Users/super/Desktop/100MSDCF -t C:/Users/super/Desktop/JPGHere is the full set of options.
