Around a year ago I expressed an interest in filters. However the people I spoke to said that it's pointless to buy filters because of the post-shot editing possible on the computer. Since then I have spent more time after each shoot editing photos on the computer (I use Picassa). Although I can make some improvements, it's very time consuming. I would rather have a better base to work from and the choice of additional editing, rather than it being essential to do so. Particularly as I don't always have the time to sit in front of the computer.
So I was wondering how much other people do use filters?
I am quite keen on landscape shots, and being in the UK there's often discrepancies between the sky and land! From the research I have done, I think what I am after is a graduated neutral density filter?
The brand Cokin has been reccomended to me - do people on here support that/ have any other suggestions? What sort of prices am I looking at? Also what are the benefits/ differences between the round and rectangular filters? I only have a single lens at the minute (18-70mm), and though I would love to have a wide angle lens, they're a bit out of my price range at the minute! I assume if I ever do save enough pennies for that, the different sized lens will require it's own filter(s)?
Feel free to impart any other wisdom on me, although I'm not so good with the technical language... I have read some of the older threads on the topic, but I'm not sure if this is an area where advice goes out of date or not. Please forgive me if this is a stupid thing to ask about; I'm still a relative newbie.
Thanks in advance.
