Why is there a “Develop Only” film processing option?

Develop Only includes chemical processing of the physical roll of film, but does not include digital scans of the resulting images or physical printed copies. There are a variety of reasons one may choose this service, but the Develop Only service level is most often chosen by:

1) Avid film photographers who either prefer to scan their own film at home, may be experimenting with new film, or may be trying out a “new” used camera for which they want to confirm is in good working order. 
2) Customers who have discovered rolls of film in their own storage or the personal effects of a loved one, or who recently purchased camera gear with undeveloped film inside (camera bodies, side pockets, etc.).

Digital scans and prints can still be done at a later date.
