Abstract: Some embodiments of the image editing and organizing application described herein provide an automatic enhancement process that includes vibrancy adjustment. The vibrancy adjustment increases the saturation of multiple pixels. The saturation of each pixel is determined by subtracting the lowest component value from the highest component value. The process determines an overall saturation of the image using a histogram. The histogram is generated using doubled saturation values for pixels with blue and green as the highest component value.
