Yesterday, I posted a photo of the moon and over the last few days I have been asked about how I photograph it. Rather than answer in comments, I thought I would do a post to explain settings and such-forth and so-like.
When I take the photos of the moon, the first thing I always do is fit the camera to my tripod. It is a lot easier keeping the camera steady when you are not holding it hehe. I also set the camera to take photos with the wireless remote control. Although if I am not sure where I have put the remote, I set the camera on a timer. That way, there is no sudden jolt on the taking of the picture.
I also take photos with different shutter speeds and ISO settings.
Here are a few with the ISO settings and shutter speeds. The first six are dusk, with the next four being dark.
