Red channel - Using a road flare

[Charles DeRosa]

howdy-

 

any suggestions for a gel (or good technique) to mimic red flare light. Shooting on the Red and (rather ironically) the red color channel gets eaten up (and as a result breaks down) so quickly when using pure red light. It seems as if the exposure range over exposing is really cut down.

 

Suggestions...and explanations are welcome.

 

Thanks

If the scene is only lit by red light, then you can record some info in the other two channels by using less reddish lighting, thus keeping some sharpness, and then timing it to pure red in post. Some people use magenta gels, for example, instead of red gels, to keep some detail in the other two channels (blue and green).

 

If you are using the RED, I would also start with a base color temp of daylight and use reddish light relative to that base, rather than start out at 3200K and start gelling lights redder or with magenta, etc.

I Love to study David's posts much better than 2hours of daily school informations;)
