Trouble with laser @ a disco

[erichfernandez]

on Monday we were shoting at a Disco with a green laser.
after a few reels we noticed some dust on the image. When we check
filters & lenses, we noticed some little points in the SENSOR.
any advice?

[Noah Kadner]

ooops- ruh roh. Gotta clean that sensor...

[erichfernandez]

we don't know what is that...

[Jay A. Kelley]

Looks like damage..

Step 1: Cry for a little while.. Let it all out....
Step 2: Call bomb squad.

Jezz... I hope I am wrong here...

If you have a good magnifying device like a loupe or sensor cleaning kit, try to take a good look at the sensor. lasers can damage your sensor and/or potentially the OLPF. This may be something that needs to be repaired by RED. The second image especially does look like damage / burns to me. :-(

Wow! If that is laser damage, the light show is operating way outside the safety rules... consider what your retina would look like, if your eye was where the lens was. (Silicon is generally a lot more heat-resistant than live tissue).

[Jarred Land]

lots of laser damage going on lately... you guys gotta be careful :)

But most people don't have giant lenses focusing the laser beam onto their retinas.

It´s a damage sensor, just hade the same problem here, ooouuuhh expensive :-(

The laser burns I've seen before were purple like that, on a 1/2" XDCAM.

[Noah Kadner]

I guess better the sensor than your eye...

Like I said! OVF is from hell!!!

Just kiddin!

Hope you get your camera patched up soon!

Those purple dots scared the hell out of me.
I was wondering about that as well as we shoot many shows that include lasers. Never had that problem yet ( knock on wood), but is there a certain filter that would help protect the sensor that you know of from laser damage?

I imagine a one way mirror over the matte box might help a bit- though this could give an odd effect to the footage.

Saw a broadcast camera on a Jimmy Jib have the CCD burnt by a laser. £6000 damage. No laser light should ever be allowed to shine directly into a lens...

[Tom Mitchell]

I was just out on a 3D job, and we had the same thing happen. took it to red Europe and we where informed it was laser damage. laser did look cool 3D but with the risk to doing that to your sensor its seems a bad idea, and it was suffering from the rolling shutter effect like mad.

what i would like to know is can you get a filter that could stop this from happening?
or is there a any safe laser systems that can be used? also is there a laser system that wouldn't produce the rolling shutter effect?

but let this be a warning, if it can damage a chip think about how delicate you eye is!, now that's food for thought when you walk in to your next nightclub

[Jean Déraps]

This is scary stuff... anyone know what would be the best way of preventing such laser damage to the sensor?

What does a sensor replacement cost for a RED One?

Sure, lens cap! :rolleyes:
Sorry couldn't resist, I know this is a serious issue and would like more info on it.
Is the issue only when looking at a direct or reflected laser, or are all lasers potentially dangerous, even if not looking directly at the source?

[Noah Kadner]

Sounds like it was Panic at the Disco. Sorry also couldn't resist. Something about lasers makes me giddy... :party:

ND filters should negate the laser light, but it also depends on the wavelength of the laser. You could also get some optical glass that is meant for the wavelength of lasers being used. Or go to the extreme and cut some welding glass. So then you can't see anything. Ha! While we're at it, a welding arc can also damage a camera too. Unfortunately, ND filters are not usually what you want in club environments or other places that are generally light-starved. It's just an issue of being careful with your camera when it's around lasers.

In most night club type situations, lasers should not be shining directly onto patrons or in directions where they may shine directly or reflect into someone's eyes. That said, I unfortunately see it happen quite a bit. Larger concerts and more controlled venues are usually a lot better about this as far as the audiences are concerned.

It's not a problem with RED, but can happen to any camera as has been pointed out in this thread. Film cameras too, but at least with film you would only scorch your negative unless it's a real powerful laser. I suppose if the laser is powerful enough it could do other damage.

Well - If you could wait, use could it as a reason to go to the Mysterium-X

[erichfernandez]

Thanks guys, we are gonna contact red dudes!!!, when we have some news i´ll tell you.

[Daniel García]

Exactly, see it as an opportunity to upgrade to the new sensor... and learn to never do it again :)

But most people don't have giant lenses focusing the laser beam onto their retinas.

That is true if the beam is spread out, a big lens captures more of the light than your eye. But if the beam is collimated, the traditional pencil-thin laser beam that just scans around, you could really get all of it into your eye. Any individual eye has a smaller chance of getting hit, since the eye is a smaller target, but if you have a big audience...

I'm guessing the laser show was aimed over the heads of the audience, and the camera was on a jib and lifted into the danger zone (?) Otherwise I'd expect a lot of lawsuits, besides just the camera damage...

Hi,

just did a job a while back involving green lasers and it was fine even when they were hitting the lens, but only because we were using a 35mm adapter ... that thing the R1 made more or less obsolete ...
Lots of fun though, these lasers, dollying through the beams really rocked ...
