Two things to watch for with color heads in general are: 1. Are you using the proper mixing box for the type of film you use? 35 mm film uses a different mixing box than 6 cm film, which uses a different box than 4' x 5' sheet film. 2. The bulb placement can be critical when you install a new bulb. Ed Reuss teklabs!edr
