Great chart! I look forward to this data being added to the Reciprocity app. Until now, I have simply used the Ektar numbers in the app, cross references with a chart that I found a while back and...
I have a light meter app that will take a picture of the scene and record all the relevant info including geo coordinates. If the reciprocity app did that, I would gladly pay a lot more for that...
Since you're going this far already, it would be really nice if you could add a feature that would allow it to take my camera out and snap the pictures all on its own. This would be really useful...
Provia 100F actually goes to 4 minutes before needing to account for reciprocity. It is a great color film for long exposures!
Glad someone finally asked what Velvia filtered means. I was always...
Thank you for the info, heind61 and Sevo!
Thanks to a fellow large format forum member, I was able to track down a proper fitting 77mm Heliopan 3X filter. I am one happy camper!
I agree...
Excellent, thanks for the info everyone! I have been having a hard time finding a 77mm filter but I'll keep looking, and I'll take a more serious look at the Schneiders :)
Hi all,
I'm curious if anyone has tried one of the Schneider center ND filters for the 105mm Fuji G617 lens? I realize Heliopan is a good alternate option to the original Fuji center ND's, but it...
Here's Fuji's data sheet for Velvia 100. You're fine out to a minute of exposure :)

I believe Velvia 100 has a reciprocity time closer to Velvia 50. I treat Velvia 100F as I treat Provia 100F in terms of reciprocity.
Hope that helps!
Haha I was thinking the same thing :cool:
I used this app yesterday when I was shooting a beach sunset. My stopwatch is in the shop for repairs, so I found the included timer on this app to be super useful.
Just wanted to say again, this...
Purchased and downloading right now. Great utility!
Good info. I am going to give it a try with Portra 160.
Excellent. I hadn't found that section of their website. Thank you for the link!
Unfortunately that chart doesn't have my lens. But all of the various 75mm lenses on that chart are also showing a 67mm filter thread size, so I'm guessing that's what mine will be as well.

Hey everyone. I've done some searching and I did find this chart: http://www.schneideroptics.com/pdfs/photo/LensCharts.pdf (the thread I found is from 2006, so I didn't want to post in such an old...
