External flash. No film will register light that is not there. The hue you
describe is a shortage of reds. The only way to alter this is for you to put
red light there when you take the pic - flash. The internal flash is
generally too weak to do this, and in any case is mounted too close to the
axis of the lens.

Sealife do a dedicated set of guns for this camera, which may be useable
with other Sealife or other brands of camera shouod you decide to ditch film
in favour of digital at some point.

I remember film..... we did it in history a few weeks ago ;p

For shallower water, you can use a colour correction filter (different ones
needed for blue water such as the Med or Egypt, and green water such as the
UK), but this will only reduce the other colours by similar amounts,
restoring (nearly) the normal balance - ie they remove even more light, so
it needs to be bright in the first place.

For anything deeper, or in lower light conditions, get an external flash
(cover up the unternal flash if it has one) and get in CLOSE!
