I noticed that someone mentioned increasing development in a reciprocity situation. That should be clarified...
The normal development compensation in reciprocity territory is to reduce development. The reason is that the reciprocity effect may not apply equally to all differing brightness values in a scene. In other words, if one has a situation in which the low values fall in the plus 1 second range but the highlights fall in the minus one second range then the highlights will not be exposed at the reciprocity effect for the film whereas the shadows are exposed at the reciprocity effect. So the normal development compensation is to reduce development since the relative scene brightness ratio is greater then what it would seem.
Now having said that, if the scene brightness ratio is such that the highlights and shadows all fall within the reciprocity characteristics of the film then one may decide to develop normally (would increase negative contrast) or even to expand development which would increase negative contrast to a greater extent.
