Abstract
A system, a method and computer-readable media for applying curve effects to a digital image. Multiple curve effects are selected to be aggregated. The curve effects are applied to test pixel values. The outputs from this application are used to generate an aggregated look-up table. The aggregated look-up table is used to apply the curve effects to the digital image.
