I'm basically thinking on the classical uses to place a part of a photography on a precise zone, i.e. if I place something that with normal measurement is Zone IX on Z VII (I underexpose 2 stops), with the genuine Adams Zone System you can play with developping time I can over develop a little and obtain more detail on high zones. On digital I don't know how can you apply the different developping times, and of course we can't neither apply different developers, water bath etc.., etc.. as he does. Is there a way? Thank you for your comments Saludos cordiales Lluis El 23/01/2009, a las 21:38, George Lottermoser escribi?: > The Zone System really does hold > the secrets of metering and exposure > and works well with digital or film. > > Zone Theory: > Meter gives you Zone V - Middle gray > Each one stop increase in exposure = one Zone lighter > Each one stop decrease in exposure = one Zone darker > > I just did the following with the M8/50 lux > Point camera add wall with texture. > Meter reads 1/125 sec at f:1.4 = Zone V - middle gray > > So: > > 1/4,000 Zone 0 = Black with no detail > 1/2,000 Zone I = Black with some murky detail > 1/1,000 Zone II = Black with some detail > 1/500 Zone III = Dark gray with good detail > 1/250 Zone IV = Dark gray with maximum detail > 1/125 Zone V = Middle gray > 1/60 Zone VI = Light gray with maximum detail > 1/30 Zone VII = Light gray with detail > 1/15 Zone VIII = Lightest gray with detail > 1/8 Zone IX = White with some detail > 1/4 Zone X = White without detail > > Try it - It works to place any metered value where you want it to be. > Black cat = Zone II or III depending on your personal preference > > Regards, > George Lottermoser > george@imagist.com > http://www.imagist.com > http://www.imagist.com/blog > http://www.linkedin.com/in/imagist > Picture A Week - www.imagist.com/paw_07 > > > > > > _______________________________________________ > Leica Users Group. > See http://leica-users.org/mailman/listinfo/lug for more information
