Why Go Digital?

No costs for film, chemicals, paper. No need for darkroom space or

darkroom technician. Immediate access. Interface with computer

publishing tools.

Is There a Downside?

High initial expense. May be less image quality than

film. Archiving file format for future use

is impossible to anticipate. Complexity of equipment.
