Ektar too contrasty for outdoor portraits?

[Edwin Beckenbach]

Ektar is the cleanest neg film yet.

Agfa Ultra 50?

[Drew Wiley]

Agfa is extinct; but if it wasn't I'd bet Ektar is "cleaner". Ironically, some of the most
accurate color I've ever gotten with difficult subjects like fluorescent lichen came from
the early-style Agfa chrome films (pre E6). Grainy as hell, but wonderful color. Had to
do with the way the color dye clouds were dispersed in a much different way than is done today. But I'd settle for 8x10 Kodachrome if the corner minimart would agree
to stock and process it!

[Ben Syverson]

Raise the contrast as
much as you want with Portra, and it still will not be as saturated as Ektar under
analagous circumstances

It will look nearly identical... I would challenge anyone to do a controlled test and prove me wrong, though!
