I caution anyone getting excited about using Ektar for Fall Colors. I have tried it for that purpose several times, including the year it came out, and was underwhelmed with the results compared to my slide film shots. Not just a bit, but vastly underwhelmed. Same goes for shooting Tulips/flowers. I expected spectacular results, like I get with E100VS/EBX/Velvia, but no such luck/results. How Kodak can tout this as a replacement for slide film is beyond me. I think they would like people to believe that, but its not true.
Anyways, it is an excellent negative film, it does do great sunsets, better than any other neg out there, and for that particular use it does equal slide film results IMO. However, it does have issues with blue casts, especially in shadows, that most other Kodak films dont have, and it can require lots of post tweaking to get the colors, saturation, and image right...unlike slide, which scans with perfect colors straight out the scanner.
