Training a new camera op today and he pulled me aside in the middle of the shoot to tell me he was noticing a black halo around the subject ton stage. It was during a shoot so there was not a lot to be done, I took it back to the studio and sure enough there is a black halo around the subject's head. I have never seent his before, it did not show up with the HPX300 (the main camera at the shoot). The HPX170 was at 720/60i. we white balanced because there was a mixture of 5600k and 3200k light. He originally had the camera on auto iris but I had him switch over to manual. He switched from a shutter of 1/60 to off. Everything he did kept the halo. The only way to get rid of it was to zoom back to a medium shot.

Any ideas on what caused this? If I missed any needed info I will supply it.

Couldn't help but spot this in a post just below yours...a quote from Adam Wilt's review of the HPX250:

"If you need more latitude still, both cameras offer three levels of Dynamic Range Stretch. Like the Shadows & Highlights adjustments in Photoshop or Aperture, DRS uses local contrast adjustment to bring up shadows and hold down highlights. Overdone, DRS can show diffuse dark halos around bright objects and light halos around dark ones; it’s a powerful tool but one requiring discretion in its application (Panasonic warns that unless you have a scene with strong contrast and deep blacks, DRS may introduce noise into unnecessarily-lifted shadows)."

It's on the second page of the review. It may be Pany's first attempt at DRS as an undocumented feature on the hpx170? May have nothing to do with it. Thought it interesting though.​
 
Never seen that before, but my guess would be along the lines of Al MacLeod's... I would guess that you had DRS on level 3.
 
Thanks guys, I have never seen this before and the fact that Barry hasn't either makes me feel better somehow. I will check the camera and report back.
 
the dude is probably possessed. demon detection is a little known and unadvertised feature of the 170
