How is film development calculated?
Film development is often estimated based on the shots of a 35mm format. Digital cameras do not use this unit, and it can be a source of confusion. In general, whenever your film is developed, they will allocate their costs accordingly. However, you don't need to worry about this when going to the photo lab. Simply tell them how many pictures you have taken and they will make sure to calculate it right regardless of what camera you are using.
