Real-time gradient-domain painting

We present an image editing program which allows artists to paint in the gradient domain with real-time feedback on megapixelsized images. Along with a pedestrian, though powerful, gradientpainting brush and gradient-clone tool, we introduce an edge brush designed for edge selection and replay. These brushes, coupled with special blending modes, allow users to accomplish global lighting and contrast adjustments using only local image manipulations
