Tip:  Try color correcting during the video editing.  All of our website videos are minimally edited.  I prefer the video to look like what I actually saw during the dive. 

Note on color corrective lenses: They work by attenuating the light colors other than red to restore the balance, i.e. they remove some portion of the non-red light...thus less photons reach your CCD.

In reduced light conditions, the filter will make it difficult, if not impossible to see what one could see without a color correcting lens.
