Summary: Don't by this scanner if you expect anything close to 4800 dpi. I bought this scanner with the intention to scan my slides. I was not able to get the resolution I expected from a 4800 dpi scanners.
Summary: This scanner is a major disappointment. Scanned color slides are out of focus and too soft to enlarge beyond 4X6 prints. 35mm and 2.25X2.25 Scanned negatives contain distracting/ugly halos around the edges of ALL highlights that turn enlargements into waste paper.
Excerpt: When I bought this Scanjet 4890 I was looking for a scanner that would be able to quickly scan photos, slides and negatives at high quality as well as being a good all rounder. It was quite expensive when it was new and hasn’t always given me the quality I expected.
Pros: quick, decent software, good images after some repeats and fiddling
Summary: Le HP Scanjet 4890 Photo Scanner est intéressant à plus d'un titre, pour scanner des photos posées sur la vitre le résultat est impéccable, pour scanner des pages de bouquins ou des documents de même. Mais pour ce qui est des transparents, diapos ou négatifs la netteté n'est pas là.
