    Yeah of course he was referring to a very dark and very color distorting sunglass lens. I don't think that has much to do with the original post.

    There is a lot more than esthetic reasons to modify away from normal. These days they are making night scene movies in full daylight by using black filters.

    "Black filters" you mean spray paint on the lens? That would certainly darken things...

    I think he means mounting a black body device on the front surface.

    They use ND filters but you can also do the same thing in your camera. Try this set your iso at 50 or the smallest you can go and your f stop at 8 and shutter 250th sec and take a picture then change only the f stop to f16 and then f22 or larger and see what happens. Do this in m mode on your camera in the mid-day.

    Many photographers wear wide brimmed hats for outdoors photography because tints and polarized glasses also affect their photos.
