Making high-contrast shapes in Capture has been a design staple, and now for the first time you can create detailed, full-color vector shapes, right from your mobile device! Simply open the app and switch from black and white to color mode in the shapes panel to vectorize artwork and photos.
Use the edit panel to crop, erase, draw, and fill in areas, and reduce the number of colors in your shape. Preview your vectorized shape using the preview mode before saving to your Creative Cloud library.
Color Shapes are currently available for iOS only.
