This slide was made in 1984, stored in a binder and not touched for 30 years. There were “dust” spots caused by the plastic holder which I didn’t try to clean off on the slide but cleaned up with NX2 in PP. Amazing quality after 30 years with no color fading.
This digital image is from an Ektachrome 100 transparency from 1984. I used the NEX-5T with 55mm Micro-Nikkor close focus lens and pointed it at a lightbox about 6 inches away
