I took some pictures from an observation deck and found that I was getting reflections from both my self and the interior lights. would a circular polarizer work to get rid of the reflections? If so, any suggestions on a good one that won't break my bank account?

Likely it would, yes, but the degree of effect will depend greatly on the sun's angle and position relative to your shooting location.

Polarizers work really well when the glass is at a 45º angle getting reflections. If the light source is coming from nearly directly "behind" you then the adjusting the polarizer may not do much to help (but you can always change how you stand so that the polarizer can work more effectively.)

Keep in mind that the polarizer will "reduce" the reflection (possibly quite substantially) but may not necessarily eliminate 100% of the reflection.

If you can stop light reaching the glass from your side in-front of the camera (in the view of the lens) then you wont have reflections. Just get close to the glass & use something (hat, coat, dark cloth...) to block the light causing the reflections. Usually much more effective than a CPL :)
Where you can't get close to the reflecting surfaces (perhaps they're part of the subject) a CPL used correctly can be a great help.

Um. No. No idea.

When it comes to what image quality you'll get, the lens is the most important part of any camera, and the filter is part of the lens.

Thats why, when it comes to filters, the only thing I'm looking for is the very best.

Putting the lens, with a lens hood on it, right up against the glass works too.
Yes that works fine, if the angle of view allows it & if the glass is free of vibrations (not vehicle windows).
If your using a rubber lens hood you can often pretty much ignore my provisos.

I think your problem is from direct reflection off of the glass.
And a CPL doesn't filter out direct reflection.
The book Light Sciene and magic is a good book on this subject.

Personally I thought a CPL was to filter out polarized electromagnetic waves reflection......
When these polarized waves strike all non metallic SMOOTH surfaces it creates POLARIZED reflection ( glare ).
The book Light Sciene and magic is a good book on this subject

Polarized reflection is different then ( direct ) reflection.
Direct reflection falls into the family of angles, in other words when your lighting is a certain angle you get direct reflection...

Polarized light is light that is or has been
Emitted
scattered
reflected
refracted

If the subject has a smooth non metallic surface and if the light is polarized
then I can under standing using polarized filer.<snip>
All light that does not come from a laser is unpolarised. That list above of polarised light covers all light - emitted, scattered, reflected or refracted - and is essentially meaningless. The light sources in the observation room the OP mentioned will be unpolarised and the reflections from the glass will be polarised and so the cpl will remove the reflection if used correctly.

Is there something wrong with the OP photo?

I was editing my post as you were quoting me.
I didn't read the ops first post very well at all.
And was trying to get it edited before anyone quoted me.

I don't want to take this thread off topic.
But some light is polarized and some light is not.
Florescent lighting is polarized light.
And so is any light the has been reflected refracted or scattered ..........

If you want to talk about polarized light that is ok but I prefer it would be done in its own thread.
