  • 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 :)

Advice needed!

We have a job that requires some high speed shots of paint spray guns, the issue is, there is a lot of overspraying... as the object they are painting is
a 50 million dollar jet, and we will be in a very large hangar with multiple paint guns. I'm concerned about both particulates landing on the lens front
glass as well as being sucked into the red and damaging the interior.

Does anybody have experience in sealing the red against this type of thing, or advice on filtration to use in front of the body to prevent paint -> lens
contact?

Thanks in advance.

Screw in UV or clear filter on the front. Large poly bag over camera & lens with hole cut out for front of lens, front sealed with tape. Leave bottom at least partially open for ventilation. Could also use a rain cover if you don't mind paint getting on it, but a disposable poly bag is probably the way to go.

Don't change lens in the spray room.
 
Sounds like a Spin Tech from Innovision or some kind of system that blows air across the lens could work for keeping the lens clear of paint.
 
It might add some ergonomics complications to operating the camera, but honestly getting an underwater housing might be the way to go if you're going to use your camera.

It's basically the only way to create an air-tight seal around your entire camera without risking fast overheating issues. You'd have to figure out some way to support the whole rig though - maybe an easyrig system?

Perhaps you could seal the camera with sort sort of plastic wrap and rig a filter from a ventilator mask with the proper filtration for whatever's being sprayed.
 
Use a splash bag or other submersible enclosure the seals off the camera from the atmosphere.

With high volume/ high pressure spray heads, there will be microscopic particulates and volatile fumes everywhere.
 
People are seriously suggesting "just rent"...? Besides the questionable moral behind this, doesn't this scream for a long hassle with insurance companies if sth goes wrong?
I would probably also opt for an underwater housing, but I guess they are still expensive for REDs, and it will be covered with paint afterwards, so also renting won't be possible.
I think this is one of these jobs where DSLR shooting is valid.
I'd rather risk an A7R/S in this http://www.bhphotovideo.com/c/product/937742-REG/dicapac_wp_s3_waterproof_case_for_mirrorless.html than a RED - mine or rental.

One more thing that I just thought of, is establishing a steady directional airflow with big, slow turning ventilators. So either always shoot from behind the line of ventilators or before each scene, direct the airflow away from the camera towards the spraying. But if this will be covered/documented like an event, this would be much to cumbersome and at one point paint dust will be everywhere in the hangar anyways...

Hi Jason,
we did exactly just that for private jets, and we used water housings. (go pro for timelapse and small housings for the epics) for the camera protection of course but also because it's ATEX regulated area and you are not allowed to use electronic devices without protection.
i would not be surprised if it's the case for you too?
 
If it's a manufacturing plant, then you'll likely be required to have you and your equipment properly covered and/or sealed. ATEX directives mean atmospheres with harmful dust or particles require protection because of the harmful nature of the products in use.

If it is a private hanger, you may have a different arrangement but we were always suited up in the paint rooms while doing Gulfstreams because there's no avoiding the destructive nature of paint sprays, not to mention your health is important.

I'd suggest a minimum 4 mil bag for your gear trimmed to the accessories you need with velcro along the edges to seal it. That way you aren't damaging a housing or rain bag that costs big $ to replace. Metro vac makes small computer vacuums that have attachments allowing you to suck the hot air out from the bag while operating if heat is a concern.

I'm not suggesting, nor do I think anyone else is suggesting just renting gear and not protecting it. I was just saying in that type of a situation, I wouldn't want my personal camera getting fucked up. A beater rental body and some lenses that need a good service anyway makes more sense. I also said to budget or bill for the guaranteed servicing that is going to need to be done.

I shot time lapse with 35mm Mitchell at the Ocean for a year.......housed in a small mini bar refrigerator with side cut out and clear filter.

The frig stayed plugged in and kept temp cool and salt water out.

That's a great point. Fine paint spray is a fire/explosion risk. Any sparks in the spray room - even from switches turning equipment power on/off is a big no-no.
