Sony DCR-HC1000 overexposure |
|
|
Hi,
I have an extremely annoying problem. When an area is overexposed, there is
a vertical white line from the top to the botton of the screen (both on the
LCD screen of the camera and the actual footage!).
I use the automatic exposure setting.
Regards,
John.

Almost all CCD-based camcorders will do this for bright points of light.
It's called 'vertical smear' and only the very high-end video cameras have
the chips that don't produce that effect. Basically, there's nothing you can
do other than try to keep the bright lights out of the picture. |

Are you sure this is happening on over-exposure? Sony consumer camcorders
use HAD ccds, which have a tendency to smear a point light source
vertically, e.g. if you shoot a lit light bulb in front of a dark
background, you'll get a vertical streak.
It's not a malfunction. It's part and parcel of the HAD ccd, and the trade
off that you make for increased low-light sensitivity. It happens with my
prosumer Sony VX2000, but it's not something that I particularly mind.

I was afraid this would be the case :(
Thanks for your response, Cail.

I was shooting in a restaurant, without video light. The lightbulbs
on the wall resulted in this vertical streak.

I experience this as a HUGE drawback.
I think I will swap the HC1000 for a Panasonic GS400, which (I hope) will
not have this problem.
Thank you for your response, PTravel.
