Suping an upcoming shoot with talent against a black cyc. It’s meant to be a dark environment, but there will be graphic elements added around the talent in post. Thinking some led tracking markers might be useful here. I’m reading that they can be handmade with a diode, battery and some tape, but wondering if anyone has used anything a little more turnkey?
Also seeing some interesting laser pointers that make a point grid, but that would really only work if you can control how many dots it shines. Would like to avoid having 100+ tracking markers to paint out.
I have used led tea lights with great success. Buy a pack of 20 on ebay for $10. They are a little harder to mount. I found that using an red diode clamped to a battery was fiddly but a little lighter in weight. You could clip them to a black curtain or stick them up.
That’s the thing. Modern leds are quite bright. I’ve heard horror stories of tracking markers causing lens flares in low light situations, which, like… I think I would just walk into the ocean at that point.
I like @PlaceYourBetts tea light idea. Just don’t get the ones that flicker.
Our engineering department happily made a bunch of the little red diode ones for me 7 or 8 years ago for a night shoot at checks notes the Universal City Walk in LA. We did limited testing beforehand, and certainly didn’t check their relative brightness next to a bunch of giant neon signs. They were completely invisible on camera. I guess that’s better than flaring the lens? Thankfully there was plenty to track, so it ended up not mattering.
Maybe it cuz I was always picking up tracking markers that the last guy never turned off, but I’ve had horrible experiences with tea light tracking markers. I think about these things constantly and I prefer to have a variety of objects and, more importantly, ways to attach them to things.
i tried to use laser pointer with green laser and “disco” prism to add trackng marks to xhromakey bkg, but it was a lot of glass in scene (windows, etc) so marks was clearly reflected and even re-reflected from glass to scene, so decided not to use pointer
The lasers I used I just put on the rails that the electricians use so they where next to the main lights hitting the chroma backdrop ) and it was no hazard and incredibly quick to setup vs gaffa-konfetti. Had 12 of them and filled out a pretty large stage
