Matias Nicolas Posted October 5, 2015 Share Posted October 5, 2015 Hi! When using flashes/strobos with epic or alexa or "X" camera, there is a moment when you see the flash, you don't see the flash, or you have a middle straight tinny or "ugly" line of the flash in the frame. Even if you try changing the frequence of the flash you have this problem. We know that is cause of the shutter and the freq of the flash ... Is there any solution about this? Some equipment that synchronize the flash with the camera? Link to comment Share on other sites More sharing options...
Robin R Probyn Posted October 5, 2015 Share Posted October 5, 2015 (edited) You could try Sony F55.. it has a global shutter.. so should capture the flash or more likely to than rolling shutter.. had the same thing recently on a commercial shot to look like a catwalk in part .. even with a whole load of flashes going off.. did some tests day before and it didnt really look good enough.. was decided to add in post.. how they did that I don't know TBH.. There might be some flash gun gizmo .. but rolling shutter I think is always going to be a problem..

Premium Member David Mullen ASC Posted October 5, 2015 Premium Member Share Posted October 5, 2015 Flashes with longer times can work with rolling shutters, I heard they used an LED strobe for "Straight Outta Compton", and that was shot on Red cameras with a rolling shutter, and I've use Lightning Strikes Papparazzi strobes without problems on the Alexa. I think I've used Atomic Strobes with minimal problem. Link to comment Share on other sites More sharing options...
Robin R Probyn Posted October 6, 2015 Share Posted October 6, 2015 Hi Dave Thanks for the info.. I had a feeling there must be some device to do it.. would an F55 with global shutter make any difference do you think.. with an ordinary stills camera flash unit.. Thanks Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted October 6, 2015 Premium Member Share Posted October 6, 2015 The global shutter would work fine with a strobe, the only issue with a normal still camera flash (which is very short) becomes, like with a film camera, having it sometimes happen when the shutter is closed. But you could extend the shutter time to increase the likelihood of capturing the flash. Link to comment Share on other sites More sharing options...

Maximilian Motel Posted October 16, 2015 Share Posted October 16, 2015 I haven't used these, but they might be worth a look: http://www.attitudelighting.com/equipment/lightning-strikes-250k-linear/ Also, if you have a speedlight or something like that lying around, try using it at maximum power, that makes the flash duration longer, in combination with a longer exposure, which could help.
