brandi_carballo Posted February 5, 2014 Share Posted February 5, 2014 <p>I am having a problem with my 5D mark ii. I am taking photos indoors, of food, very well lit with overhead light and 2 strobes. The bottom half of all of my photos are black, it is not a shadow, it is solid black. I tried changing lenses, same problem. The weird part is, when I point my camera out the window at the neighbor's house it works fine. But all my indoor shots have the black part. I tried re-arranging my lights, I am confident it is not a shadow. I don't know if my lens release is not opening all the way? But I also can't figure out why it would work fine looking outside. I did try moving around, too, shooting from various distances and angles and still have the same problem.</p> Link to comment Share on other sites More sharing options...
ruben leal Posted February 5, 2014 Share Posted February 5, 2014 Seems like you are exposing a shorter time than the strobe synchro speed of your camera. Could you try using a speed around 1/125s? Link to comment Share on other sites More sharing options...
niels_van_velzen Posted February 5, 2014 Share Posted February 5, 2014 <p>My first thought is dat your shutter speed is too short for your strobes. Try setting the camera's shutter speed a bit slower, e.g. 1/60s. Are you putting the strobes on high speed sync?</p> Link to comment Share on other sites More sharing options...
ruben leal Posted February 5, 2014 Share Posted February 5, 2014 Just confirmed, the sync speed for the 5D Mk II seems to be 1/200s. This means the shutter curtains are opened completely only when you select a Tv speed of 1/200s or lower. When your camera is set to a faster speed, like 1/500s, the second curtain is already closing before the first curtain is fully opened. (You may google flash synchronization for further detail). You must also consider a delay when a wireless trigger is used, reducing the effective sync speed, perhaps in 1/3 to 2/3 stops, in this case down to 1/125s.

bobatkins Posted February 5, 2014 Share Posted February 5, 2014 <p>With some studio strobes you might have to go to 1/60 or even 1/30s. The 1/200 sync speed only applies to a hotshoe mounted Speedlite.</p> <p>If you don't understand sync speed and high speed sync, check this out - <a href="http://www.bobatkins.com/photography/technical/canon_speedite_high_speed_sync.html">SYNC</a></p> Link to comment Share on other sites More sharing options...
brandi_carballo Posted February 5, 2014 Author Share Posted February 5, 2014 <p><strong>Thank you all so much!</strong> That was exactly my problem. I lowered my shutter speed and reduced the brightness of the flashes and it worked perfectly. I really appreciate the help!</p> Link to comment Share on other sites More sharing options...
