beamer, artificial light and flash

<p>Hi all, I usually have an orange filter on my flash and hence balance the available indoor light with the flash's colour. WB is set acordingly. Now I tried to take a pic of a guy giving a talk in these conditions, while he showed a presentation with a beamer. The beamer's part turned out too blue as expected for a daylight source and WB set for the orange artificial light. How could I prevent this, given the other light sources? Any experience with "multiple colour artificial light sources"?</p>

<p>You have four options, as I understand it:<br>

1) Gel the beamer with CTO<br>

2) Gel the room's lights with CTB<br>

3) Use a honking big strobe such as B1600 monolight and overpower room light<br>

4) Shoot RAW, fix in post.</p>
