peter_muller1 Posted May 18, 2004 Share Posted May 18, 2004 I will be vacationing overseas next month and anticipate a number of situations where I will need to use exposures of 5-60 seconds (for 400 speed film). Are there any film types/brands in either transparency or negative that are especially tolerant of longer exposures without special color balancing filters? Thanks.

dale_dickerson2 Posted May 18, 2004 Share Posted May 18, 2004 I find the Kodak Portra NC handles 60 sec exposures very well. I recommend this print film for 15-90 sec exposures. I have no problems at 5 sec with any of the 400 speed Kodak or Fuji films. After 10 sec you can get some color shiftswith some of the films.

lex_jenkins Posted May 18, 2004 Share Posted May 18, 2004 Reala (ISO 100) isn't as fast as you'd like but it handles long exposures very well with good reciprocity characteristics and neutral color response. Link to comment Share on other sites More sharing options...
dale_dickerson2 Posted May 18, 2004 Share Posted May 18, 2004 I agree about Reala. Since Peter was looking for 400 speed. I did not bring it up. Link to comment Share on other sites More sharing options...
andrew booth Posted May 18, 2004 Share Posted May 18, 2004 All the major film brands have data on their web sites about film reciprocity failure. Link to comment Share on other sites More sharing options...
jbq Posted May 18, 2004 Share Posted May 18, 2004 Provia 100 needs no compensation up to 2 minutes (same thing for Acros 100). Provia 400 to 30 seconds. Link to comment Share on other sites More sharing options...
gregg_cook Posted May 19, 2004 Share Posted May 19, 2004 Second the nod to provia for transparencies. Velvia is good for firworks and stuff to keep saturation and use longer exposures for trails. (5-10 second multiple pops.) I wanna catch lightning with it. Did it before with plain old s-100 print and it works. Link to comment Share on other sites More sharing options...
roger krueger Posted May 19, 2004 Share Posted May 19, 2004 Fuji NPL (120 & 4x5 only) has great reciprocity chacteristics that make it nearly as fast as 400 for print films. But you do have to deal with it being a tungsten balanced film. Link to comment Share on other sites More sharing options...
raymond of rish Posted May 19, 2004 Share Posted May 19, 2004 I would say even Fuji's specs on reciprocity failure for Provia are a bit conservative, and may be fine for exposures much longer than specified (several minutes or longer). In my experience, there has been absolutely no color shift. My experience with Reala in this respect (or superia-reala, for that matter, as I'm assuming you're referring to 35mm) has been decent, but not as good as Provia. Some of my best shots with Provia have in fact been very long exposures in the dark. Out of curiosity, what are you taking pictures of that requires such long exposures?

peter_muller1 Posted May 20, 2004 Author Share Posted May 20, 2004 This will be 120 film, not 35mm. I have a Linhof Technorama 617S with a wide-angle 72mm Super Angulon XL lens. The Schneider wide-angle requires a center density filter that reduces exposure by 1.5 stops. Hope to take some indoor available light shots as part of a barge trip through Burgundy.
