Quickly and easily paint Impressionist Art: Load a photo from the gallery, choose your brush settings and paint with your finger. Impressionist Painter will get the color of the pixel from the photo that corresponds to when you touch on the canvas. Combine brush shapes, color, and effects to easily create a work of art.
Impressionist style painting done with a combination of brush shapes and the velocity effect.
Brush Shape: Choose circle, square, or spray brush shapes to paint with.
Brush Color: Normal color mode will extract the same color as the photo. Grayscale color mode can be used to paint in black and white. Complementary color mode will convert corresponding color to the complement color.
Brush Effect: No effect will paint the brush as normal at a default brush size. Velocity mode will adjust the brush size based on the speed of your finger on the screen. Accelerometer mode works similarly to velocity mode however, the painting happens when the device is tilted and rotated.
