In fact with the copper you can watch the gelatin of the resist break down as the etch progresses and make inferences about how the plate is etching and vary the acid strengths to control the contrast range. That control is one way in that you can't back up and widen the tonal range of the darks after moving on to etching the mid tones or change the range in the mid tones after moving on to the lights but seeing them etch does give a control that the plastic plates apparently lack. It means there are way too many possible variables to master in copper to have perfect control but many people have mastered it with beautiful results. Jack
