Hi,
Now most people process their film images in digital dark rooms (PhotoShop etc.) and then print the images out. This is also what I usually do. However, I have a slide projector and I do enjoy watching the large projected image. For this purpose, I still need high quality slides. It's expansive to output digitally processed images to slides. I thus decide to try slide duplication.
Attached image is my first result. The left one is the original. The image is taken by a 4" F9.3 telescope with a 67 camera. The film is Provia 400F +2 push and exposure time is 2 hours. Apparently the contrast is low (even after +2 push!!). The right one is the duplicated image taken by a 645 camera. The film I use for duplication is E100G +2 push. These two images are scanned with identical setting and are not furthered processed after being scanned. What you see on the monitor should be very close to what I see on a lightbox.
Now I can enjoy this image on the large screen.
