Hi majeba (Barbara),
Regarding ...a certain kind of film for taking night pictures...
For slides or prints, a higher speed film will allow you to
pictures in low light conditions. However, if you are taking
indoor pictures with incandescent light and no flash, the pictures
will turn out yellowish. There is a slide film that compensates
for this, called 640T. It's ASA is 640 (good for low light)
it is color balanced for incandescent light (indoors). This
be the film you're thinking of.
