There are two general types of film emulsions in terms of crystal shape: classical grain emulsions and modern tabular-grain emulsions. Both types can be either regular crystals or core-shell.

Among B&W films, only Ilford Delta 100/400/3200, Fuji Neopan Acros 100 and Fomapan 200 are tabular-grain, all others being classical.

In this video, we will look at the different grain types, how they work and what are the biggest differences.
