Hi, Stephen The longest successful exposure I have timed with my LX is 12 minutes.
I can't comment on the film you used, but in my experience, there are big differences between films in reciprosity properties. I have only worked with slide films. From my experience, it kicks in at around 1 minute exposures with Velvia, while Provia endure 4 minutes before deviations are hard to handle. The weirdest film I have tried is the Kodak E100VS. I find it unpredictable at exposures longer than 2 minutes. Usually, it will give amazing blue colours, but not always. With the Provia (100F) being as good as it is, I have never bothered to really study the Kodak. hth, Jostein ----- Original Message ----- From: "Stephen Moore" <[EMAIL PROTECTED]> To: "Pentax List" <[EMAIL PROTECTED]> Sent: Thursday, February 26, 2004 5:28 PM Subject: LX: Long exposures on auto > A question for the LXers: > > What's the longest (ballpark figure) successful exposure > you've made using the LX's automatic, direct-metering mode?
