Hello there I orderd linear polarization filters and I put them like microbehunter said in his videos when I look at the image it is blurry I focus it as much as I can but its still blurry, Any suggestions that might help I will post a piture I took thank you.

It could be lower quality polarizers or too close to an image plane.

A picture might help. Are they film you cut to fit?

Did you peel the protective coating off the film?

Yes I did peel the layer off but still didn't work I think they are low quality 😞

It could be. You might have more luck getting them from a known vender like edmund optics. Sometimes they're available used.

Decent quality camera polarizers, which are faced with glass on both sides and sometimes anti-relfection coatings, are another option. A larger one to fit the field iris and a smaller one to fit between the head and stand. These often don't have the full extinction of better polarizers, but would likely provide sharper images.

Linear polarizers are best, but the circular ones can work well if you get the orientations right (flip them).

It's also possible that camera vibration, shutter shake, etc. have contributed to the blurred images. Are pictures taken without the polarizers sharp?
