Jon de Zwaan Posted October 10, 2012 Share Posted October 10, 2012 Hi guys, I did some test shooting in lowlight and high ISO on my GH2, nothing scientific, just pushing the camera. I noticed a strange dark pattern on the lower half of my footage on high ISO settings. Exactly the same darker line as this guy gets: https://vimeo.com/19563762 Sometimes it's visible, sometimes not, at ISO 2500 or lower it disappears. Is it a faulty sensor or normal behaviour in low light? I use the EOSHD Unified 88Mbit hack. Quote Link to comment Share on other sites More sharing options...
Fly-Catchers Posted October 10, 2012 Share Posted October 10, 2012 From what I gather this is a common issue with the GH2 in lowlight conditions where you are tending to be underexposured. I get it at any ISO but particulary higher ones. Sometimes its very obvious- other times you have to look really hard for it. Filming at 30p or 25p eliminates it completely. Just one of those things!

Jon de Zwaan Posted October 10, 2012 Author Share Posted October 10, 2012 Thanks a lot! It's really a relief to hear it's quite common. I would've hated it to return my nearly brand new GH2. Quote Link to comment Share on other sites More sharing options...
Fly-Catchers Posted October 10, 2012 Share Posted October 10, 2012 Of course I meant to have said 1/25 or 1/30 shutter speed to eliminate this banding! But no Jon not a fault as such, more a quirk!! Quote Link to comment Share on other sites More sharing options...
kirk Posted October 10, 2012 Share Posted October 10, 2012 In addition to the slower shutter, using the vibrant color setting helps keeping noise down. And turning off the two "intelligent" modes too. Quote Link to comment Share on other sites More sharing options...
