I'm travelling to Southern Europe this summer and i'm planning to shoot a mix of landscapes and portraits - in both 35mm and 120 - for a college project. I'd like to keep the 35mm as fine-grained as possible so as to potentially mix it with the 120 (at a print size of about 11x14"). At the moment i'm sort of torn between Kodak Ektar 100 and Portra 160. I've shot Portra 160 on medium format in the past and i've always found it to be a very impressive film, is it worth going the extra yard for Ektar? Lighting levels won't be an issue as i'll be under intense sunshine, with the possibility of some use of flash indoors.
