  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

This Is NOT "FUD" - Just Curious ...

since my epic flew to me by plane...and my Red travelled the world by plane...and i dont have one single dead pixel on both cams...i would conclude...this is maybe BS :)

I think you will find they get masked, it's nothing new.

This phenomenon was discussed here back in 2007, link
 
He mentioned that it was a bigger problem with CCD's because an entire row would die. I think a CMOS sensor would only have a single pixel die, and that could get averaged in during the bayer math.
 
I think this affected the genesis cameras they used on Superman.

I think certain sensors have protective elements either by design, or by design of their OLPF.

I'd be more concerned about what gamma radiation Is doing to your brain and skin first.

Additionally, certain sensors may have had some origins related to outer atmosphere or space telescopy - I'd imagine those are more resistant to gamma radiation, wink wink.
 
When is the last time (anytime) you have seen someone post about a dead pixel or column here? And how many RED ONEs do you think there are flying around? Almost every commercial flight flies over 20,000'. The average altitude for a commercial plane is 35,000'.

Don't worry guys commercial air travel is perfectly fine... CMOS sensors by their design protect against radiation much better than CCD's do..

This whole thing is only true ( and likely where the rumors come from ) if your RED travels into outer space... on CMOS sensors individual pixels will die one by one ( good ) from radiation outside our atmosphere. Almost every digital cameras that NASA sends to space come back with less active pixels than when it left. Coincidently CMOS sensors were originally invented by NASA's JPL laboratory.

You do need to worry about shooting Lasers directly into your sensors though.... that can kill.
 
I'm positive some body does jobs for the redbull skydiving team, and did a halo sky dive with 4 r1's. can't find the post but it's been done, probably many times already. partial space isn't even an issue for RED :)

if anybody can pull up that vid, that should disprove it once and for all... we should take this one to myth busters too kekeke

jarred do you have any ballpark on the laser brightness we should watch out for? we do this all the time, never have any problems, but we do it all the time and i would like to make sure it's kosher, and if it isn't, i will change the laser brightness..

Any of them...
 
And before anyone gets some stupid idea that the laser issue is a RED-only issue, I just want to say that this affects ALL cameras. If a laser is powerful enough to hurt your eyes, it's plenty powerful enough to scorch a camera sensor.

I was going to say that there are a bunch of Nikons that have been flying around the Earth every 90 minutes for the past decade that would care to disagree with the statement that cosmic rays quickly kill cameras!

I've worked a number of years for NASA TV and from what I've learned, Gamma rays have very short wavelengths so they can travel through thick objects, but once one hits an atom, it done. That's why they can travel through the space shuttle and knock out CMOS and CCD pixels (and genes, etc), but they can't make it too many miles through the Earth's atmosphere. I just edited a show for This Week At NASA where video cameras the astronauts were using on the ISS and they were full of missing pixels, but I also just flew across the US with my Canon DSLR and no dead pixels (again). I was also told at NASA that US astronauts aren't supposed to reproduce after they travel in space because of that 'gamma rays hitting and knocking out genes' thing. It's not suck a big deal if it knocks out a gene that has already had it's instructions carried out, but if one hits a sperm or egg DNA gene that will go on to fertilizer, that's a big risk for a birth defect.
