Littlestream,
Regarding your orange cast,perhaps you could try choosing neutral
from your camera's white balance setting, if any.And try to meter
away from the light so that the exposure will attempt to balance
itself out.
Yep, a tripod or placing your camera on a power box will also
help.Use a timer so that any residual finger or hand wobble will be
eradicated.
The grainy noise is due to your camera's auto ISO function.If you
have manual controls, you can leave the ISO at a low number , say
50, 64, 100 or 200.I believe that you are using a Canon
Powershot?If so, use the manual mode and slow the shutter down to
approx 1/10 and open the aperture to F2.8.Leave the ISO at
200.
That should work.jOhO, will the manual settings work for this sort
of lighting?
