Abstract
Methods, systems, and non-transitory computer readable storage media are disclosed for generating a lens blur effect in a digital image with interactive light source adjustment. The disclosed system determines a gradient mask by detecting edges of a luminance map comprising luminance values of pixels in a digital image. The disclosed system determines a highlight mask by thresholding the luminance map to determine a subset of pixels with luminance values meeting a threshold luminance. The disclosed system also generates a gradient-highlight mask including pixel values from a combination of the gradient mask and the highlight mask. The disclosed system further generates a highlight guide image comprising indications of one or more light sources in the digital image based on the gradient-highlight mask and the highlight mask.
