Thanks for the amazing work, is there a way to get images in varying lighting conditions within a specific brightness range ?

For now, the full list of the image transformations is in the Readme and doesn't contain changing brightness but it's totally possible. In particular, this project is using scikit image so you can easily add your custom image transformations. I saw this in the documentation :

Feel free to edit the code an make a pull request ! If you need help with this just tell me.
