SoftBox is a tool for photographer to use Screen as a light box. This is also an extreme exercise of PyQt. I am really a idiot on programming. So just don't give any attention please.
pip install softboxAfter the installation step above, SoftBox now becomes available in Python. And you can simply use it by type the following commands in your Python interpreter :
import sys
import softbox as sb
sys.exit(sb.begin())
