Hi all,

have a series of long exposure shots planned in my head... talking 30s to 2mins or so and was just after advice on reciprocity (sp??) and colour films particularly suited to this? Haven't got much experience with slide film yet and people seem to say exposure etc needs to be nigh on perfect for good results; so preferentially print films. Any implications for development? :)

You can use slide film, provided you meter and grad (if necessary) well. Provia 100F is good uncorrected out to about 2 minutes, with 1/3 stop correction for 4 minutes.

As for print films, I'm not sure personally... though I would recommend Portra 160 in general. Apparently it's fine to 15s, 1/2 stop for 30s, 1 stop for 60s and 2 stops for 2 mins. After that, I'm not sure.
 
Fomapan 100 has a dreadful reciprical failure though I have had decent results with long exposures.

This example was metered for 8 seconds which with recipricol equated to 56 seconds....

sorry just re read the original post .... didn't realise you were looking more towards slide film...duh! lol

Anyhow, perhaps the example helps someone else if not you Mel

Ha, great shot btw... Yup thinking colour films..

Thanks Woodsy, Portra 160 seems to be where most people are telling me to start. No ektar lovers by the looks of things. might give Provia a go! Although, I currently use an iphone app as my meter so may need to invest in something dedicated if i want to try slide film seriously.
 
No worries :) slide film needs to be accurate to around half a stop, especially when going for extended exposures. I personally am not a huge fan of Ektar... Something about the way it renders just doesn't tickle me. Portra 160 however is fantastic. I find the coulda to be accurate, the right amount of contrast and more dynamic range than any other film I've ever experienced.

A note with slide films; try not go to ridiculous exposure times, like 15 mins + because I believe you start getting colour shifts that are really difficult to correct for. A general statement, and films will vary, but just a rule of thumb for me personally :)
