OT: I see dead pixels...

Sorry I couldn't help myself.

The first time I discovered dead pixels in a project shot on my JVC GY HD110 I freaked out. After learning how to correct it (the help came from someone here as usual) I became hyper-sensitive to dead pixels. Now I'm noticing them everywhere. There were some in that DSLR vs. film comparison posted a week or so ago. Then I noticed some in a doco on television. Now my wife is watching an Adam Lambert concert on television and two of the three cameras have dead pixels. Is this inherent to HDV? Has anyone else shipped out a project only to notice a dead pixel or two after the fact?
Once I notice them, it drives me nuts because I can't stop staring at them. Am I alone here?

No. No you aren't.

Last week we watched the F1 and we spied one camera with 8! I realise this is bordering on the edge of being a trainspotter, but it definitely IS something that I can't avert my eye to. A bit like the moth in "Antz" or "Bugs Life"(?) : "But it is so beautiful!" zzzzappp.

Grazie

Ok - I belong to the club -dead pixels are really getting all my attention, especially in my own cam's. My Canon MVX2i has one that is at at about 80% white when the cam warms up. Where do I find the mentioned instructions how to remove it, without killing this poor pixel's neighbours?

Cheers,

Christian

Christian,

Try a google search or you may get lucky like I did and someone here will have a link for your camera (assuming it is possible with that model).

http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=634477Here's a link[/link] to the thread I posted some time ago. It's not specific to your camera but has some useful information from some of the vets here.

Cheers!

I read somewhere that there's always dead pixels with LCD tech. The only issue is where it is located. :D But I've also read that no manufacture will replace a LCD screen unless there's more then X dead pixels.

Yep, nothing will train a person to spot dead pixels like an HD100 :)

I'm always surprised how often I see them as well.

"I see dead pixels..."

They don't even know they are dead...

On the reality show 'The Biggest Loser', they had one of their cameras with a dead pixel for two whole seasons. I thought, damn, what cheap bastards. Get that thing fixed!

We shot for half a day inside a beautiful cathedral for a festival film and no one noticed anything on the monitors. I even double checked after learning my camera was prone to them. It wasn't until that evening when we were going over the dailies on a 32" monitor that we noticed we had a problem. From now on I'm going to power up with the lense cap on to be absolutely sure. They ought to really stand out then. Maybe?

DGates wrote on 4/12/2010, 11:20 PM

yep. They'll stand out against a dark lens cap.

And bang-up the gain till it is full-on, and then adjust back till the background gain-grain subsides. You'll see it/them - I did.

Grazie
