I guess I understand the idea of exposing for the shadows and developing for the highlights; it refers to the near inability of the chemistry to affect the density of the only dimly exposed silver in the shadow region. What I don’t understand is why there needs to be such a large shift in the meter setting within the incident system (metering and using the setting from the shadows at say 3 stops darker than the full sunlight). IS it true that no matter what incident reading (shutter/f-stop combination) we get that consequent development of any time and temperature will only reach back and develop usable densities 3 & ½ stops, so that for a situation of SBR 8 I must blast the film with what seems like 3 stops extra light and then do a weak/quick development so as to not let the highlights (which were blasted) get out of control?

It is just stunning to me that an incident reading of the sunlight hitting the scene can be that far off and that reading the shadows (with a bump of one stop from the prescribed adjustment to the ASA/SBR chart) is the way to compensate. Strange but true?
