Claim One:
1. An image editing method, comprising: rendering a downsampled adjustment image of an input image by determining an adjustment curve for each tile in a plurality of tiles of the input image, wherein each adjustment curve defines a relationship of image editing controls that is applied to pixels in the tile, wherein the relationship is derived from one or more image characteristics of each tile in the plurality of tiles, and wherein the downsampled adjustment image comprises a plurality of pixels and each pixel corresponds to the adjustment curve for a tile in the plurality of tiles; upsampling the adjustment image, by applying an edge preserving upsampling algorithm, to a full size adjustment image that is the same size as the input image, wherein each pixel in the full size adjustment image corresponds to a new adjustment curve; and performing pixel by pixel adjustment of each pixel in the input image based on the new adjustment curve of a corresponding pixel in the full size adjustment image, thereby obtaining an edited version of the input image.
