Is there an idiots guide to filters?

I'm thinking the one that stops the sky over exposing. Is there an "all rounder" or do all filters do different jobs?

How do they attach to lens?

if you want sky to stop over over exposing you coud try and graduated neutral density filter, ive got one and its helped me plenty of times for landscape and certain city scape shots such as stuff taken from a high location across roof tops...etc
 
I am going to get a CPL filter, might get a graduated neutral density filter now after reading the above. :thumbs:
 
Quite glad I read the Ken Rockwell link as I was about to buy CLP for my Sigma 10-20. Not sure if I will bother now.

How does it actually fit onto the lens?
What about polarising filter?

I use the Cokin "P" system ....the P relates to the physical size of the square filter

here's what i got for a Sigma 17-70mm which has a 72mm filter thread size

you buy a threaded adapter which screws into end of lens [size 72 in my case]
then a filter holder which clips into the adapter
the holder has 3 slots or the WideAngle one has only 1slot to reduce vignetting
then you buy P size filters as required

cheap adapter/holder/filters off eBay...then when you really know what you like/need, buy decent filters

I like landscapes so got a 0.6 [2stop] and 0.9 [2stop] graduated ND filter to start
grad ND's are available as soft for landscapes, or hard for where there is a definite horizon such as a seascape

if you want to slow down the exposure for those milky waterfalls - get a solid ND

good luck....:D
 
PS

"P" series PL-C polarisers are stupid money - i use a standard screw-in Marumi DHG PL-C


and - Luke - yes, it does throw a band across the sky even at 17mm
not too noticeable - but there if you know what to look for
....at 10mm..:shrug:
