Filters, Can you help??

Hi this is my first, request for advice on the forum, so a big hello from the UK. I have recently purchased a 10-20mm lens with the intention of "having a go" at landscape photography. Do I need, or more importantly, would filters enhance my images, if so which ones are the most popular choices? There are so many to choose from.

Regards

For landscape work, I consider a polarizer indispensable. Your 10-20mm lens may require a thin filter designed to prevent vignetting on wide angle lenses.

Graduated neutral density filters are also very useful for landscapes. Search this forum for a ton (oops, I mean tonne ) of information on the different manufacturers, sizes and grades.

Cheers,

Filters are essential for landscape photography. Since NPN is a treasure throve of good information, I dug up this little gem: Filters For Outdoor Photography by Darwin Wiggett. Look for it in the Nature Photography 101 index, May 2002.

There have been a number of discussions on NPN on the subject of using post processing in Photoshop instead of GND's; you might want to look into that before buying a bunch of potentially expensive filters. However, a polarizer is a must and there can be situations where the only way to reduce light intensity is with an ND filter--Larry

Polarizers, a neutral density filter or two, and a small assortment of graduated neutral density filters.
