NOTE: For “Type 1” internegatives (4 x 5 format), all of the even numbered
steps are computed internally using a curve fitting algorithm. Actual
internegatives only contain the odd numbered steps.
AUTO EXPOSURE AND FILTER PACK COMPENSATION
The Auto function initiates the automatic exposure and filter pack
compensation. Since internegatives are used as a set up tool rather than a
process control tool, measurement data is not stored in channel memory.
Data currently stored in channel memory is not destroyed.
