Actually, black is not a colour. It has absorbed all the visible light rays, and allows none to reflect back to the eye. Which is why a black car will be so much hotter than a white car out in the parking lot. That light energy has to go somewhere, so it is turned into heat instead of being reflected. It's for this reason that painters seldom use pure black, we mix it up from other colours. Used by itself, it kills the painting in that area. It's just too strong, and throws all the other tonal values off. By the way, if you're ever having difficulty getting the values correct on something, take a B&W photo of it. It will display only the values and not confuse things w/ those pesky colours.
Nice camera! Simple, basic design. Reminds me very much of my Nikkormat FTn, except that the Nikon has the shutter speed dial around the lens where it belongs:} Oh, and your lens focuses and mounts backwards of course.
