#photography protip: A very approximate but often useful quick and dirty heuristic for comparing the overall sharpness of two versions of the same image is to save each as a jpg with the same quality and other parameters. The sharper image will generally result in a larger jpg file. (A bunch of stuff can break this, so it's not a perfect metric. Noisier images will tend to also produce larger jpgs, for example).
