Torch Lighting Effect
on Oct 26, 2010 at 11:11:39 pm

Firstly, sorry for posting this here, i just didn't know where else to post it. Ok, so I was helping film an interview today and it was pouring down. The director promptly pulled out a torch with a bit of what looked like clear, transparent, yellow tape over the head. I asked him what if it was tinted acetate and he said it was a gel of sorts but that he wasn't too sure. The purpose of it was to aim it at the camera's lens in order to recreate the flares we associate with sunlight.
If anyone out there has any idea what he was using with the torch I'd be extremely grateful to know. Many thanks...

When you say "Torch" I assume you mean what we here in the United States would call a flashlight, yes?

Sorry I don't know the answer to your question but I wanted to clarify the issue for other readers who may not understand British colloquialisms.

For us a "torch" is lit piece of wood or something similar that you hold in your hand in order to navigate through a cave or jungle

Yes an English 'torch' is an American 'flashlight'. But um wow shooting one into a lens to make sunlight lens flares- that's just silly (or daft as the Brits might say). Perhaps he's been watching J.J. Abram's Star Trek too much...

Yes, it was a flashlight and I agree it sounds daft but it looked 'utterly fantastic' as we might say in Britain. It did the same as the glow effect on Knoll Light Factory if you know what i mean, and the torch was shone from the side at a very slight angle.

To give you an idea, click on the link below and watch the video. In the first 10 seconds the effect or something similar is used multiple times to recreate something that's doesn't look like a lens flare but technically is.

Yes, traffic from America is not allowed to watch the video in order to be fair to British tax payers - at least that's the theory as I understand it.

My only thought is that I'd much rather create this effect in software than "bake it in" into the camera footage. That way you can revise and control the effect.

Although the idea of doing it in Post is attractive, it looks much more natural when 'baked' in.
Sorry for the horrendous quality but the link below is to a youtube video which displays some of the flares that I'm talking about. Do you have any idea of any transparent yet coloured materials or gels which one could somehow attach to the front of a flashlight?

I've seen this done before.
Of course its not a wise thing to do, its always better to have a clean image THEN drop some light factory on it. Same effect ... more control.
id say it would be tried on something like a music video but not an interview dude.
But i suppose they know their client so.......

Yeah that looks ok but could have easily been done in post without tying your hands in terms of when the flares hit. Not too mention a very slight chance of damaging the chip in the camera. But I'm sure the director felt like a total badass shining his flashlight into the lens. Sigh.

LOLOLOLOL
Sigh indeed. Mack that effect can be created so easily in post.
in case the DP did not realize we are in 2010 so like Apple says ... there's an app for that.

Soooo...if you're looking for the "organic" effect with the torch/flashlight, why don't you just shoot a piece of black cloth or card, do the torch move, then composite it in AE in Additive or Overlay mode?

You now have the torch effect as part of your clip library, and you have complete control of the timing and intensity.

Ok lemme wrap this all up. He used the gel because it was raining and the gel looked much more realistic than Knoll Light etc. He in fact used something similar to the link below. And I was lucky enough to see the locked cut and I wholly agree that this torch/gel idea of his was much better than anything that could've been done in post. Thanks anyway all.
