However, I am still confused about the comment in your prior post in response to Mark's:

"You can loose nearly one stop by developing in either Kodak Microdol-X or Ilford Perceptol (they are identical). When used full strength these extra-fine-grain developers loose about 3/4 stop when compared to D-76. The results will be normal contrast negatives."

in light of your more recent one in repsonse to my post:

"Standard developers will all deliver the same contrast if the development time is correct. "

Contrast and density are two different beasts. You can expose a film with a given exposure and give it normal development in a standard developer like D76/ID-11. The result will be a negative with a normal contrast and densities ranging from nearly clear film in the deepest shadows and maximum density in the highlights.

You can double the exposure from above and use Perceptol or Microdol-X. This will give you negatives like above (normal contrast, densities from nearly clear to maximum density) but with finer grain.

It is impossible to underexpose a film and get normal densities and contrast with special developers or longer development. All you'll get is empty shadows and raised contrast.
