    f/16 at 1/125 second

    The "rule" is called "Sunny-16" and the idea is the f/stop is f/16

    Then the shutter speed is 1/ the ISO or rated speed of the film

    In my case I rate 400 speed film at 250 for landscapes and so my case I use f/16 at 1/250 second

    In your case, I assume you were using a slow, fine-grain film that might be 100 speed so you could use f/16 at 1/125 second

    You could, if you are using 100 speed film, choose to expose it as if it were 64 speed, and give f/16 at 1/60 second

    For landscape in black and white it would be good.

    You really need to take a meter reading, with the meter set for your film speed. A small aperture like f16 or 22 will give good depth of field meaning that the subject will be in focus from close to the camera into the distance( depending on how you set the focus). Sharpness is normally best from about two stops down from maximum aperture, and falls off towards the smallest aperture. There are some good books available on the subject of exposure that may help. Check Amazon, although I pick up lots of photo books in charity shops. Alex

    That's a myth.

    The part about the worlds largest natural darkroom? Can't be - my boss told me that one.

    p.s. STEVP51,

    I really wanted to make my first post:

    f/16 at 1/125

    without any further explanation...

    Because really, that would probably work for anybody, anywhere, any (black and white) film*.

    *With the obvious exception of the specialty slow and super fast films.

    The latitude of negative film to overexposure is why simple box cameras work so well.

    I think Stephen really meant the gray card and the whole 18% is not middle gray thing.

    One thing I know for sure about a gray card: If you meter it... and shoot it as meter recommends... it will be properly exposed.

    Not to hijack the thread, but I have often wondered if the dull grey (or gray) of my vintage Tamrac Expedition was chosen so that it could act as an in-the-field grey (or gray) card. It works... when in doubt meter the camera bag.

    Use a densitometer or spectrophotometer to check it out if it's really 18% gray.

    I possess neither of these fine tools, but I do have negatives that are exposed to my expectations, so I would guess that it must be close enough to serve the purpose.

    Or compare the reading you get off of it with a reading from a grey card.
