What are the advantages of Digital?
Professional image No darkroom, film, envelope Post Processing Consultation Exposure Latitude Contrast optimization
Exposure latitude
the extent to which a film, image plate or film panel can be over or underexposed and still achieve an acceptable result
Contrast Optimization
Application of additional processing ‘normalizes’ the image
Dark regions are made lighter and lighter regions darker
What are the two problems we are reducing by using Digital Radiography?
Improper exposure
Poor darkroom technique
