Hi guys,

First thank you for reading this post.
I'm going to film a project where the main light is from a lighter in the total darkness :o
There are different scenes where the light will be created from the sparks of the flint only :huh:
To make everything more difficult is that the lighter has seen in the frame.

My question is:

how can I increase the light from the sparks especially in sync with them?

I was thinking to use a battery's car(shorting positive and negative pole together) but how can I sync lighter and it together?

Do anyone has a better idea?



All the best!

Michele

I'm not sure who makes them, but I've seen flicker boxes which look at a source in the frame and dim up and down accordingly via a small photometric sensor. Something like this, I'd say, can work for the effect your looking for.


or you can build it yourself:
