willscarlett Posted November 11, 2016 Share Posted November 11, 2016 <p>Does anyone remember the reciprocity for Fuji Neon 1600? Found the data sheet online, but the reciprocity info wasn't listed.</p> <p>https://www.fujifilmusa.com/shared/bin/Neopan1600.pdf</p> Link to comment Share on other sites More sharing options...
glen_h Posted November 13, 2016 Share Posted November 13, 2016 <p>How far do you need it to go? I would use a table from the most similar film that I could find. </p> <p>http://www.kodak.com/global/en/professional/support/techPubs/f32/f32d.jhtml</p> <p>TMax 3200 is 2/3 stop at 10s, and 2 stops at 100s, either aperture or time increase. </p> <p>That doesn't sound too unusual.</p> -- glen Link to comment Share on other sites More sharing options...
bethe_fisher Posted November 13, 2016 Share Posted November 13, 2016 <p>I use an app for reciprocity that's also got adjustments for filter and bellows extension. I checked it and it doesn't have Fuji 1600 even listed and it's got a lot of films. Fuji Acros needs no adjustment until it's pretty long and the other Fuji films in the app don't need an adjustment until longer than about a minute. I've never used the 1600, so I don't know which it's more similar to.</p> Link to comment Share on other sites More sharing options...
glen_h Posted November 15, 2016 Share Posted November 15, 2016 <p>Pretty much, I never worry about reciprocity. If I am making 10 minute exposures, I am guessing in the first place, and don't guess close enough to correct. </p> <p>Many years ago (when my FM was new) I was out boating on a full moon night. (Boat tied to shore for the night.) I went out, set the camera on a nice solid rock, and used a locking cable release to do about a 10 minute exposure on Ektachrome 200. That was pretty much a guess, partly based on how long I wanted to sit and wait, but it came out nicely exposed, maybe a tiny bit dark.</p> <p>Another year, I did a 45 minute exposure on Ektachrome 64. Longer partly for the film speed, and partly as it could be a little lighter. (And maybe, but I suspect not, for reciprocity reasons.)</p> <p>I did know about reciprocity failure, but what else would I do?</p> <p>Actually, one should be able to calculate somewhat the ratio of sunlight to moonlight, but I didn't even try that. Color films tended (I don't know about now) to have worse reciprocity problems than black and white films. </p> -- glen Link to comment Share on other sites More sharing options...
