Karel Bata Posted February 26, 2012 Share Posted February 26, 2012 (edited) In a couple of weeks we're giving the new Olympus i-speed 3 cameras a trial run in a 3D mirror rig. At what speeds does supply flicker start getting noticeable? We're on 50Hz AC. Are there 'safe' speeds? The studio hasn't the supply outlets for any 10Ks, nor do we have the budget for Unilux lights, so we're thinking of using three 5Ks run off different phases to help smoothe out peaks and troughs. How effective is that? Cheers! Edited February 26, 2012 by Karel Bata Link to comment Share on other sites More sharing options...
Gregory Wilson Posted February 27, 2012 Share Posted February 27, 2012 Hi Karel, Usually around 72fps you will get flicker with small tungsten units, sodium vapor etc. A good rule is to keep your lights tungsten and 2k or larger. There are charts that show safe speeds with HMIs. It is always a good idea to makes tests. greg Link to comment Share on other sites More sharing options...
Albert Smith Posted February 28, 2012 Share Posted February 28, 2012 I believe you'll be safe with 5K. lots of other posts on this though look around the info is on here. Link to comment Share on other sites More sharing options...
