Roger is correct. Delta 3200 is not to be used whenever light is low. There are conditions where it should be used, and in that case the best SUITABLE technique is employed.
I use it for weddings at reception and develop it in Rodinal. No flash no tripod. For sure there are number of other use (e.g. subway train,...)
And about the grain. Who use Delta 3200 he knows what grain he will get and it is a problem or advantage (I do not use it if a problem). Who want to start to use it he will be better of to learn how to do it, and when, and why.
Anyway I like the grain on some photographs, it adds drama.
