shooting tv and computer screen

[robert blu]

I need to take some pictures of my studio and my living room, both with an image on the screen of the i-mac or the television. I want to use the rolleiflex and I'm thinking which exposure time is correct related to the screen. I remember but not sure suggestion of 1/15 sec because of refreshing time. Any suggestion please?
thanks, robert

1/30th maybe safe for US and other 60Hz current countries but most of Europe is 50 Hz so you'll need something slower then 1/25th i.e. 1/15 should be safe.

I just tried this with my leaf shutter RF and at 1/30 and slower it look good...at 1/60 I could detect a black line or two in the screen...I'm in the US and that would mean 60Hz...

Ok, I took the pictures at 1/4 of second and it work ok. Just to be a little more carefull about some reflection. You can see the result here (http://www.rangefinderforum.com/forums/showthread.php?threadid=95896).
