Latitude means "how sloppy can I get and still get away with something?". It is a factor engineered into
amateur color neg films in particular, but seems to be an attractive concept to anyone allergic to using a light meter. Contrast is determined both by the slope of the specific film and its development regimen. Dynamic range is the usable part of the film curve if you do correctly meter and develop it.
Some films have more range than others. Lazy photographers convert this into "latitude" mentality,
but dyanamic range is far more useful is you understand its endpoints and how to meter for them in
specific given situations. Most black and white films can be developed in all kinds of manners per overall contrast, microtonality in middle, etc. Just depends on exactly what you are trying to achieve.
