Thanks for all the advice lads! turns out that Filmbase, where we're renting the gear, have HMI kinoflows (flicker free fluorescents!) so we're playing it safe & going with those will let you know how it turns out cheers Moira ________________________________ From: David Kidman <> To: ev petrol <>; Experimental Film Discussion List <> Sent: Thursday, August 4, 2011 3:12 PM Subject: Re: [Frameworks] fluorescent lights & aaton cameras? Hi Moira, I think I answered a question that you didn't ask. I have also shot in Ireland and the UK with the same Aaton and the frequency was exactly in phase with fluorescent lights (and no bar roll on a tube t.v., either).

Based on the 60hz rate of electicity. So 24fps is a safe film speed and i think that rule should work with regular house florescents and that would be why a 25fps camera would not work in N.A. while being fine with European 50hz systems. > >_______________________________________________ >FrameWorks mailing list > > > > >_______________________________________________ >FrameWorks mailing list > > > David Kidman +33 681 497 602
