# arwjpg

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](https://github.com/Cyb3rN4u7/Python-Image-Converter). If all else fails, you should use Sony's [Imaging Edge](http://support.d-imaging.sony.co.jp/app/imagingedge/en/). 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.

# Conda environment creation

To use `arwjpg`, you should create a [Conda environment](https://anaconda.org/). Clone this repository and change directory `cd` into it. Then type in the following.

```bash
conda env create -f environment.yml
conda activate arwjpg
```

If you need to destroy the environment, type in the following.

```bash
conda remove --name arwjpg --all
```

# Usage

To use the `arwjpg.py` Python script, make sure you activate the `arwjpg` Conda environment as mentioned above. Then type in the following.

```bash
python arwjpg.py -s [source_dir] -t [target_dir]
```

Note that

* `source_dir` is a directory containing `ARW` (RAW) files.
* `target_dir` is the directory which `JPG` (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.

```bash
python arwjpg.py -s C:/Users/super/Desktop/100MSDCF -t C:/Users/super/Desktop/JPG
```

Here is the full set of options.

```bash
usage: arwjpg.py [-h] -s SOURCE -t TARGET [-v VERBOSITY] [-e EXTENSION]
