I just bought a little slide duplicator on ebay and I need a little help. It simply attaches to the end of FD mount cameras. My problem is that it seems way to dark when I put a slide in and look through the viewfinder of the camera. The instructions are not that great. They say to use window light or try a 150Watt light bulb. So I pulled out my slide projector and when I put it up to that it is bright enough. I think that this will work, but I don't know what to use for a shutter speed...Any help and advice you could give me would be great. Patrick PS: What print film would you recommend using when I want to make prints? I will use EDupe for copying slides.
