I'm sorry but I have no information on enlarging this film as all of my work is scanned but I can tell you that a standard input color space such as sRGB or Adobe RGB 1998 would fit this film perfectly...2.2 seems nice. My scans are just about perfect with little to no work and require very little adjustment in Photoshop. The print at 1600 looks really great...especially for 1600!
