From there, you can use the paint button to draw over your image with a fully customizable brush. Also, you have another button for effects with different categories such as artistic corrections, paper effects, Color Splash and simple. The button lets you do things like crop, rotate, and resize the image, with additional tools, including one that lets you crop a specific shape. With an image on the screen, you can use the buttons at the bottom of the interface to play with the main functions of the app.
So, like most photo effects applications, in Picsart Photo Studio you can take a new photo or extract one from your photo library.
