// The script creates a history state when it starts so you can always go back if there is a problem.
// It also creates a layer set to keep all of its layers in (tidy, don't you think?).
// There is really only one thing you might want to change...so here it is.
// The last step is to do a lens blur, but this could take a while on larger images so I leave it as an option here:

// The choices here are: 
// 0 = no
// 1 = yes
// 2 = prompt

var doDefraction = 1;






// Don't change anything below here unless you know what you are doing. Or just want to play. Whatever.

// Save the state of the document before you do anything.
