Today I wanted to share with you:
the "Lomo" technique
In order to get this look I did the following:
Layer - New Adjustment Layer - Curves.
In the curves window, RGB drop down, click on Red
create an S curve.
In the curves window, RGB drop down, click on Green
create an S curve.
In the curves window, RGB drop down, click on Blue
create an opposite S curve.
Lower opacity if the colors are too intense.
I also added a Totally Rad dirty filter, "Cherry Amore".
