I was recently asked a series of questions that I don’t know answers to and in todays world is a bit hard to find sensible resources for…
The questions are:
How do the polarization (CPL) filters work? How do the ND filters work? How do the Variable ND filters work?
When and how to use polarization filters? When NOT to use them? What to look for when using them to know they are performing as expected or not doing much? What are the trade-offs?
When to use ND filters? When not to use them?
When Variable ND make sense to use instead of ND filters?
Are there any other “interesting” filters that one might want to look into?
Then there are square filters which I personally got burned with (low quality filter + demanding shooting condition = pretty much unusable result :/).
Are there any sensible materials I could read and watch about those? All that I could find was vids/materials in the style of “look at how cool is polarizing filter and now buy my presets” or “filters from this company are the best, the other are garbage” with very little practical info or knowledge
Thanks for all the help!
