TECHNIQUES FOR PRESENTING USER ADJUSTMENTS TO A DIGITAL IMAGE

Techniques for generating a preview image in an image editing application in response to detecting user input that changes the value of an adjustable parameter of a digital image undergoing adjustment. According to one technique, instead of processing the digital image through a filter chain to generate an updated preview image, a blended image is generated through interpolation of two previously generated versions of the digital image. The previously generated versions may be generated through the filter chain. The blended image may be generated in a shorter amount of time in response to the user's adjustment than the time needed to process the digital image through the filter chain. Thus, the current preview image may be updated with the blended image sooner than is possible if the current preview image is updated by processing the digital image through the filter chain.
