FFS, isn't there enough threads about the doom and gloom of Kodak? The OP asked a simple question, is there an alteranative to Portra.
Why do we have to start yet another long and bulls..t discussion about kodak?
To the OP, there really is only one alternative at the moment - it's Fuji. I wouldn't call Reala an alternative, I'd be looking at the Pro 160 range and 400H for higher speeds.
