When is it necessary or when is it a good idea to start considering filters?
I just keep on seeing them again and again when I generally browse, and I still just don't know what exactly they are used to achieve. I know there are UV filters and some others, but I don't know why i'd want to consider these options.
As well, the prices vary alot. I see $10-$50 filters everywhere. Are they all camera lens specific? Or say I get a 52mm filter...will it fit a standard lens?
I guess I'm just confused as to when I should start to consider these and if they are worth it for someone that just does general photography.
