Any time that light passes through air-to-glass surfaces (lenses, filters) you will lose some sharpnes of an image, so be prepared to lose a little sharpness when making dupe slides through the normal slide-to-camera copying technique. It's a fact of life that 1:1 dupe slides are not as sharp as originals, but that is the trade-off when one wishes to protect the original slide from potential damage caused by light, abrasion, heat, excessive dryness/humidity, condensation or being eaten by a hungry projector.
But when made correctly, dupe slides look great when projected and probably cannot be detected by most slide show observers sitting in the audience. Your photo should say enough on its own to be able to "carry" an audience whether it is a dupe slide or not, so don't worry about a slight loss in sharpness that most people will not even notice for a few seconds of viewing time. It is the over-all impact of the slide's color, composition, lighting and subject that are really important to the viewers. As to the term "duplicate original slides", meaning another original slide of exactly the same image, I prefer to call these "second original slides" so as to avoid confusion. To me, a "duplicate original slde" sounds like it is a slide dupe of an original slide. But, of course, I am easily confused. John B.
