The advantages of the individual confronts had been then distorted into the related mediocre shape just before superimposing the images to create a photographic high quality result (this process has been utilized in order to make substance photographs in the early in the day studies: [59–61]). This new compound photo have been made really well shaped of the merging all of them with their reflect picture, performing photos symmetrical in profile and you may colour.
