This is good news for Blackmagic Cinema Camera owners – finally a solution for one of two issues that continue to be trouble for some owners.
Unfortunately, there's still no reported solution for the black spot issue plaguing the Blackmagic Cinema Camera and the BlackMagic Pocket Cinema Camera. Here's a sample of that treated with humor by WideOpenCamera.
Blackmagic Design Moves to Address Pocket Cinema Camera “White Orb” Image Issues
From Dan Chung:
Several users of early Blackmagic Pocket Cinema cameras (BMPCC) have encountered an issue where bright specular highlights and point light sources can be rendered as ‘white orbs’ or ‘blooming’ in the image. I encountered this with my production unit and posted about it here. Speculation was rife online as to the cause of the issue and whether it is a hardware or firmware issue. Then on Thursday this week Blackmagic’s Kristian Lam updated users with this message on the Blackmagic user forum:
“All sensors, be it CCD or CMOS, will have a ‘blooming’ effect when during severe overexposure, the pixel is over saturated and excessive charges overflow to neighbouring pixels. It just looks different depending on the sensor type.
We are not seeing this on some of our test cameras so it might be something that is calibration related. Please contact your nearest support office and we’ll run another calibration on the camera.”

Now Blackmagic Design have moved further to reassure users that are unhappy with the image issues. They have posted images on their forum demonstrating that the appearance of these ‘orbs’ can be reduced or eliminated by a re-calibration of the camera. According to Lam “not every camera requires this but we’re setting this as the new baseline callibration. We are also implementing this new calibration in cameras that ship going on forwards but this change has already been effected since the start of the week.”
The re-calibration is voluntary and requires that the camera is returned to a Blackmagic Design regional service facility, either directly or via the reseller. It seems that for US users the cost of return carriage is being borne by Blackmagic – elsewhere in the world it is unclear.
The calibration service is not yet fully up and running everywhere but Blackmagic say it will be shortly.
