Things that I've noticed about these actions that you'd might like to know-
1. They are not customizable. It's just a flat action that you throw on a picture. What you see is what you get.
2. Just like regular instagram, these filters only look good in natural light. They're a bit extreme (but instagram filters are generally pretty extreme) in indoor lighting. In fact, I personally wouldn't use them if the lighting is bad.
If you have questions about how to install these actions, the link to download them explains how to get these to work on photoshop as well.
Good luck! And happy editing!
