How to apply effects on only part of your photo
You can select the area you want to apply our photo or artsy effects on your photographs, we call this Paint Mode.
To access Paint Mode, choose a filter, then tap on the right window where is says 'Paint' that appears next to 'Adjust'.
You have two options on how you want to paint, you can paint the effect with the brush or you can erase the effect away like we did on this photograph.
To switch between these two options, tap the button with the two squares (reverse).
Along with the options to Paint or Erase, you can choose your Brush Size (how much area you paint), Hardness (how much of the effect you want on the photo), and Strength (how much feathering you want on your paintbrush).
