Any tips on shooting welding? Suddenly have a Scarlet shoot tomorrow

[Ben Scott]

Hi all,

Out of the blue i have my first proper Scarlet-X (Canon mount) shoot tomorrow where I will be in a a workshop shooting the welding of a frame to be used for an upcoming big event in the UK.

I'm going to have a 60D in the corner shooting a long timelapse of the whole day, probably on a Tokina 11-16mm, and then I'll have the Scarlet there for shooting video.

Won't be able to light it and also really won't have any time to test before the events I am capturing start off so I was looking for thoughts on how people have dealt with those shoots in the past. Will have a 25mm and 50mm Zeiss ZF, plus a slow (f3.5) 35-105mm Nikon AI manual zoom.

I'm thinking

some 4k @ 25fps general working on the frame
some 3k @ 48fps closer on the welding and sparks
some 2k @ 60fps on the sparks hitting the floor etc

Does anyone have experience of this sort of stuff? Would you expose purely for the sparks and let that illuminate anything else? Or would you expose for the people working on it and let the sparks be even hotter .



Any tips, advice or examples would be greatly appreciated.

Thanks in advance :)

It really depends on the look you are going for. If you would like to Expose for the bead and get close you are going to need to rig welding glass from a welding hood on to you matt box and and have a lens that allows you to get and ECU other than that you would do well to shoo the welding in a very bright environment and stock up on ND's. This will reduce the latitude a little bit which will help you. remember to protect you camera.
good luck.

Thanks Yaque. No time for any rigging so just taking a ton of NDs in there. I guess I'll play it by ear.

And Scott, no results in that link you posted...

Sorry, it was a quick forum search for "welding". There have been several recent related threads.

Good luck. Let us know how you manage UV with multiple NDs and welding, and how it works for you.

[Ben Scott]

Ah gotcha. Not seen anything like that in the sub-forum. I have absolutely no idea what to expect tomorrow and it was all very last minuteso to be able to get anything will be a bonus :)

Ben,

I didn't mean any real rigging just using some welding glass ( which will be available anywhere that someone is welding) in place of an ND. welding is about as bright as the sun but you are a lot closer so try to think of it in terms of pointing the lens directly into the sun. This should put things in to context. Just my two sense :-)

[Ben Scott]

Ahh right. well we'll see what we can come up with. I am working under an NDA but will post results after June 3rd. Maybe I can get away with a couple of r3d stills. :)

Highly suggest an environental enclosure of some kind to keep grit and welding gasses out of the large vents in the camera!...
also heat may be issue..... but no one will care about camera noise... would a telephoto lens be useful to you?
perhaps a large fishtank would be usefull to you??

[Ben Scott]

Oh man I am so scared of this shoot now! Think I might have the Red doing a 5k timelapse from far far away while the 60D does closer stuff....
