The painting tools change the color of pixels in an image. The Brush tool and the Pencil tool work like traditional drawing tools by applying color with brush strokes. The Gradient tool, Fill command, and Paint Bucket tool apply color to large areas. Tools like the Eraser tool, Blur tool, and Smudge tool modify the existing colors in an image.
The power of painting in Adobe® Photoshop® Elements is in the options that you can set to specify how a tool applies or modifies color. You can apply color gradually, with soft edges, with large brush strokes, with various brush dynamics, with different blending properties, and with brushes of different shapes. You can simulate spraying paint with an airbrush.
