This is a comparison of a section of the back (dorsal) legs of the image on the Shroud which includes a positive photo and a computer reversed image (like a negative). It's a fairly large picture (1917 x 1135) you can save to your desktop and view in a larger size if you happen to be viewing it on a smaller device. You will notice there seem to be many stripes going down the legs which are the whip marks from where the Roman flagrum hit with the damage it caused. I just noticed now but I made an error so on the far right of each one is not the neck, but the feet. You might get a chuckle about that.
