What is the whole process of taking pictures with traditional cameras?

Check the camera (mainly batteries, some hand cranks with metering system, which need button cell to charge before metering).

Load film

Whitewash a stain

Remove the lens cover (especially the side shaft)

composition

Metering, adjusting aperture and shutter

Focus (the same as the above photometric steps, and the other way around)

Film winder (electronic is not needed, you can do this step as soon as you take photos)
