Although very well-made duplicates are the choice for continuously
running 3D-shows (at museums etc.) and are definitely a good idea
if you send them around in a folio, there are still certain restric-
tions.

If, for example, you plan to scan the pictures to be used in high-
quality, high-resolution color printing (such as 3D-Magazin), dupli-
cates are just NOT acceptable. In the early years, we also accepted
dupes - and it's clearly visible in the magazine which ones were the
dupes! Contrast is too strong, and the colors suffer quite a bit.
Therefore, we will only accept original slides.
