Creating a digital photo with an exposure of EV -2

On a MacBook computer running OSX, is there an app I can use to create a digital photo file with an exposure of EV -2 ?

I'm looking for something that will simulate the bracketing function of a camera but in an app.

I plan to make a set of photo files with the following EV levels using EV 0 as the base photo:

EV -4, EV -2, EV 0, EV +2 and EV +4
