Laboratory Aim Density (LAD)

In the Laboratory Aim Density (LAD) printing control method, a standard control patch specifies densities midway between the minimum and maximum of those typically obtained for a normal camera exposure.

Digital LAD

The KODAK Digital LAD Test Image is a digital image that can be used as an aid in setting up digital film recorders to produce properly exposed digital negatives and in obtaining pleasing prints from those negatives.


This paper (PDF) provides scanner setup recommendations for efficiently extracting the full density range stored on high dynamic range films.


With KEYKODE numbers, and your choice of database software, you can automatically log frame indexing numbers from negatives and workprints in a fraction of the time it takes to do it manually.
