Canon 450 filter
5 Answers
Hi
I am trying to take pics of the moon. It is coming out too bright. Is there a filter I can use or how do I set the camera to take the pics?
Thank you

As ianmunt says, you need to set it to manual control and experiment with different exposures. If you have the Canon 450d (digital version) then nothing is wasted while you experiment.
You don't say whether you are trying to take pictures of just the moon (in which case follow the advice above) or whether you want a landscape that includes the moon. If the latter, then you will be forced to choose a longer exposure to get detail in the landscape (and the moon will be washed out). So here's what you can do:
1) Buy a graduated Neutral Density filter that reduces exposure to the sky half of your picture whilst allowing full exposure of the bottom half.
2) Do as I do and take two pictures - one exposed for the moon and the other exposed for the landscape. Use digital editing software (eg GIMP) to combine the two.

ideally a low shutter speed adjust apature to suit
you also need to be using a low ISO to reduce "grain"
and if possible you need to reduce the spot metering to single point centre weighting
at that distance it's movement that will ruin the shot you need to use a tripod or something steady.
at least with a digi you are not wasting film
the downside is ... CCDs lean towards infrared which makes them sensitive with wide apertures - and in built up areas.
one possible cheat if you can't get the balance is to under expose the shot
then use a graphic editor
copy the shot and make it a negative
then use it as an adjustment overlay in a second layer
by adding the two you'll bring out the "face"
