Here is a little bracketing script.
It's not bad, but even not brilliant.
The script is older script. Today, you can write some functions better.
You can make ev and tv series. For control is a log function integrated.
A fix focus mode is also available. But this mode is not optimal working.
You can make more than one shoot pro bracketing value.
