View Full Version : Blue spot in the middle of video

Not sure if this is the right section to post this in or not.

I am getting this blue spot in the middle of my images with my new gh4/speedbooster. Can anyone please tell me why this is happening? (

Do you get it all the time or just this one shot? In this shot, by looking at the shadows on the ground, you have your camera pointed towards the sun, so this would be a sun flare. In cold weather, this would be fog on the inside of the lens. On a "coated" lens, this looks as if the coating was rubbed off in the center. If the spot goes away indoors, it's probably a sun flare.

Looks like it could be a light leak thanks to the speedbooster. Alternately, if you're using square filters on your lens and don't have the right donut on your matte box, it could be light reflecting back into the lens from the filter.

Thanks for the responses guys. Turns out we had ghosts, had someone come down and cleanse the set, we were back in action in no time!
