A petzval effect is a slight movement/blur on your image while the eyes are in focus. It is where there is a shallow depth of field, with a sharp focus. It is mainly used for portraiture as that is where it works best.
Firstly, I duplicated the layer. Using command T, I moved the anchor to the middle of the models face. I then changed W: 101.00%. using command, alt, shift, T, I pressed these 4 times to create 4 copied layers. I then selected all of the layers to have an opacity between 30-50%. To then join all of the layers, I pressed command G. After, I added a layer mask to the group of layers. Ensuring the paintbrush tool is set to black, I used this to paint any areas which I wanted to come back into focus, like the eyes/facial features. I really liked the way that this turned out as it created a subtle distorted effect. I would use this again in my portrait images to just add a different look to them.
