So I have a stupid questions about filters. I know almost nothing about shooting with filters. What’s got me onto this is quite silly. I got given a nice new pair of sunglasses, they were clearly quite expensive. They’ve a yellow tint to them, perhaps polarising (?!) but I'm not really sure what that means! Anyway, the enhanced contrast on a sunny day is great. They make things pop and it's really pleasing to the eye. It’s made me think about filters and what they could do when shooting film. Sorry if this is a dumb way of getting into the idea of using a filter but it’s a very visual way of seeing how something in front of the lens (or my eye) changes the feel and look of an image! I’ve never really used filters, I have some ND filters with a cokin z-pro but never used it in anger. I bought it and let It sit there as I do with quite a few gadgets! Does anyone have any good guides, videos or advice for a newbie looking at shooting with filters; what differing types do, and what scenarios I might want to use x or y filter for? Thanks in advance.
