Using the pre-flashing with the Bowens Illumitran does indeed help control contrast at times. I had one for a while and found the pre-flash definitely worthwhile for many shots. If you are using the regular slide duplicating film the effort is often not worth the trouble, but the effect is unmistakable. Maybe he was referring to the use of the pre-flash when he had a ton of images to copy and time was more important than ultimate contrast control? It's a 'handicap' if you consider a flatter image a handicap. As you generally gain contrast in copying, and usually shift the HD curve as well, you usually need to reduce contrast. You do this best by starting off with a slide duplicating film matched to your taking film as well as possible, then try to lift the toe area out of the murk a bit by pre-flashing. Fairly straighforward. * Henning J. Wulff /|\ Wulff Photography & Design /###\ mailto:henningw@archiphoto.com |[ ]| http://www.archiphoto.com
