Good advice, cheers! For the 120 cameras I'm also going to take Fomapan 400 which is brilliant because it's very forgiving in terms of exposure and it has a lovely tonality and grain. I'm also thinking about Velvia (either 50, but more likely 100) which isn't as neutral as Portra but I think that it might be a good for pictures around the gritstone crags to give the greens and also the grit some punch. Would you say that the Portra works well for sunsets?
