Theres a vignette tool in photoshop as well, it's in filter/distort/lens correstion. Wayne
You don't have to do it in photoshop. A lens hood suited for a lens less wide angle than the lens being used will do it.
e.g. This shot looks like it may have been taken with a 24mm lens. A lens hood for a 50mm lens will probably produces similar darkening in the corners.

Valid point - but no 50mm lens I've ever owned has been the same diameter as a wide angle.
A good point. However, I have 28mm, 50mm and 135mm Minolta Rokkor lenses which all have a 55mm filter thread so it is a possibility. A lot of Nikon lenses are standardised at 52mm and If I remember correctly, Canons are often 58mm.
Actually, thinking about it, I have done this. I accidently used my 50mm RB67 lens with the rubber lens hood for the 90mm lens and got the same effect (although it was an unwanted effect in this case!).
Which brings up another example. Those two RB67 lenses and the 180mm also share the same 77mm filter thread.

Perhaps that's an 'older' lenses type thing then - mine at either 67 or 77mm, my nifty is not
