The thematic project is 'old'-whatever that means to you.
Shooting in black and white isn't a technical stretch for some of us, but others probably don't shoot B&W much. For those with limited black and white experience, there are two black and white films-Ilford XP2 and Kodak TMAX400CN-that can be processed and printed like normal color negative films. This might be easier than using conventional b&w film and printing for this project
