Ok, if we have no definition than this is really a Twilight Zone thread. I just labelled it accordingly. cheers, caveman
REPLY: Twilight zone exposure is somewhere in the area -1 to - 1,5, depending on what the photographer wants. In order to get the exact effects he need tools able to read and set exposure with the necessary precision. This is exposure for the twilight look shot in daylight (in my example with slide film like Velva where it admittedly doesn't work that well) often seen on movies were they shoot nightime shots in broad daylight and get the twilight/nightime look by underexposing. If you what to shoot in twilight quite literally the exposure is dependent on reciprocity characteristics of the film in addition to the ususal stuff. It is far more difficult to nail expsoure with the same precision as film reciprocity doesn't really hold up anymore for many films. In addition, by following the reciprocity rules literally the twilight scene will look like broad daylight which is OK if thats what the photographer wants. With films like Kodak Ektachromes he just meters as usual in daylight and he get that effect. With Velvia he should expose for +1 when we are talking shutterspeed of a few seconds. Kodachrome about + 2. However, if the photographer wants twilight look he should expose the Ektachrome family at - 2/3. Kodachrome at 0. etc. If shutterspeeds goes into minutes the whole thing gets more complicated. P�l
