Not everybody who shoots films have their own film scanner, especially the new Lomographers or analogue users. Even I don't have a proper scanner, because every time I have the money, I buy films and save some for developing and scanning at a photo lab.
Have you ever experienced when you unloading your Smena 8M and just for fun, test firing your Smena 8M and suddenly you notice that 1 of your shutter blades is not working? You will wonder, "Argh!! What happen to my rolls?? Is it nicely exposed or a disaster?".
