We recommend that you use a matched pair of 200W tungsten lamps or two tungsten-halogen photolamps, in a fixed position, for illumination on the sides of the copy stand. Determine the best shutter speed and lens aperture combination for a given lighting setup and title by a trial exposure series, using the suggested exposure index (EI) as a starting point. Use EI 25 when processing in KODAK Developer D-11 and EI 8 when processing in KODALITH Developer. • We have been buying KODALITH Ortho Type 3 4556 (thick base) in 4×5 sheets for quite some time. Since it’s been discontinued, what has replaced it ? If you need a thick base film (.007mil), what we are offering as a substitute is the KODAK Camera 2000 CGP7(catalog number 199-1827) for the 4×5 sheet size. However you need to use the recommended developer which is the KODAK RA 2000 Developer and Replenisher and process according to recommendations.
