How to use black and white film at night?

Black and white movies are not suitable for night scenes.

If you really want to shoot black and white night scenes,

I recommend Fuji Lishi 100, which means that the night view is not bad and the color is delicate.

But don't use too small an aperture. More reliable than f8.

If you have an exposure meter, you'd better take a digital photo first, and then take a film with the same parameters. When developing, wet it (water) and add about 20 seconds of development time to make the film thicker.

You can try my method.
