Proper Settings

[katwoman85]

Hi All.  I am just a beginner still reading my camera manual online and everything.  For some reason, I still struggle with getting the settings correct for taking photos at night.  I have an EOS Rebel T100.  What are the proper settings for getting pictures to come out clear at night?  I tried numerous things and still cannot get it right.  Hope someone with this camera that takes photos at night can give me some feedback as to the proper settings.  Thanks!!!

I shot this the other night using the technique of shooting in Tv mode and doubling my focal length with Auto ISO.

Since I was shooting at a focal length of 124,.

I picked a shutter speed of 1/250th.  The camera set an aprerture of f/11 and an ISO of 3200.

Interesting shot / exposure.  According to the "Looney 11 Rule" the Moon should be WAY overexposed.

1/100, f11, ISO 100

Are you sure the ISO might not have been ISO 320, instead of ISO 3200?

Wadizzle,

Thanks.

I double checked, and yeah, the ISO was 3200. I was really puzzled about that too.

Perhaps because I spot metered on the moon?

One thing I was wrong about... I was in Av mode, not Tv. I manually set the aperture to f11, and the camera set the shutter speed of /250.

PS: Yes, it was twilight, and the moon was low in the sky. I wanted to capture the moon in that azure blue backdrop.

Yeah, I can see the Moon is overexposed, but I would have expected far more than that at ISO 3200.  Any lens filters?

Yeah. I've got a color polarizer on.

Using a polarizing filter could fully explain it.  Most of them reduce light reaching the camera sensors by 1-1.5 stops.  I think the mystery is probably solved.
