And halation is caused air/surface boundaries and reflection from film backing plate which has been utilised by infra red film manufacturers to get that characteristic bloom in IR film shots. They didn't use antihalation dyes in their films. Normal films have it though. I guess its like a lens coating for films. They've improved too, so much so that they can get film resolution of 200 lp/mm (ignoring the massive numbers claimed by some specialist films like 800 lp/mm).
. For info on ideal exposure check pp. 68 (depends on the edition) to see the complete picture. .
I checked my download of the book between pages 67 and 70 and I think that you are referring to the paragraph on OPTIMUM EXPOSURE which is on pages 66-67 in my download. I cannot see a reference to increasing box speed by half a stop to improve things but it does say that exposure should be the minimum commensurate with good shadow details. This of course is true and is really a truism but doesn't necessarily lead to the conclusion that an increase in box speed will improve the negative in terms of printing nor do the authors suggest this as a course of action that I can see.
It may of course work for you but as a general rule in photography it may well not have universal application

If you have done any research on the workflow/techniques practiced by many of the well known photographers, you'll find they vary all over the map.
Good call, Michael!!Speaking of which, what's with the title of this thread? You can't actually meter with film as far as I know. You have to meter with a meter.
So did I!John knows I'm just fooling, but I pictured using a strip of film to meter a scene and had to make the comment.

3a is obvious. Less the exposure is more the grain not taking the developer and printing into account.
The perception or subjective sense of grain ("graininess") in a print is supposed to peak at reflection densities around 0.4.
Granularity (the objective measure of graininess) in a silver negative increases with increasing density.
