Can I put a circular polarizing filter over a uv filter while shooting landscapes or portraits?
Yes, but if you are using a circular polarizing filter, there’s not really a need for the UV filter. UV filters do very little and are used more than anything just to protect the glass of the lens itself. Yes, it may cut a little haze, but the circular polarizing filter will give you rich, blue skies and cut reflections. If you do use both, you should keep in mind that you run the risk of having vignetting and increasing the amount of lens flare from the sun or from lights.
