Film scanning frequently involves working with historic glass negatives, medium and large format negatives.
Uniform lighting and accurate tonal reproduction is vital to ensure that all color information can be retrieved during processing; this often takes place during the conversion from negative to positive.
This process is often relative as base material for original transparent matter is likely to change. For example, two rolls of film may behave very differently, both in their original base material characteristic and in their chemical development.
The digitization of transparent film on a medium format capture solution is centered around a stable reprographic stand, a camera with a macro lens and some precision-made film holders for different types of material.
