If you decide to make an photograph of the potatoes you just have peeled, then it can not be other than the painting De Aardappeleters (The Potato Eaters) that pops up in your head. The dark shady depiction of farmers eating their edible golden nuggets dug out of the earth, after a day of hard work. The painting is coarsely painted, but Van Gogh wanted it that way; it had to look as if the scene was painted by a non-artist, according to (I believe) the master himself.
