Velvia Recipriocity Times

[matthew_brain]

Hi,

 

I was recently shooting in a dark forest and only had Velvia loaded.

The recipriocity times for velvia stop at 32 seconds (the best film

for this sort of thing is Provia). I usually have luck extrapolating

the recip times given to longer times that Fuji don't recommend but

was wondering if anyone else has done the work of formally working

out what the recipriocity characteristics of Velvia are beyond 32

seconds.

 

Thanks,

 

Matt

Matt,

Here is what I have found and use:

The first # is the meter reading, the second is what I shoot.

 

4sec: 5sec,

 

8 s: 12 s,

 

15 s: 28 s,

 

30 s: 62 s,

 

1 min: 2 min 13 sec,

 

2 m: 5 m

 

4 m: 11 m

 

CC magenta filters are also recommended, however I'd suggest testing to your lenses.

Good Luck!

Here's a link to an Excel spreadsheet that gives Velvia reciprocity characteristics up to 65 seconds, including suggested color correction filters:<P>

Ah just what I was looking for.

 

Thank you both for some very useful data - I love the curve and the time for 4 minutes.

 

Thanks very much
