Every photo genre has its arsenal of accessories. Portrait photographers choose light modifiers; macro photographers have extension tubes and sports photographers walk with monopods to support heavy telephoto lenses out in the field. Similarly, landscape photographers pack a few accessories to help them work with the natural environment, time of day and elements to maximize their time. Here are a few key accessories that you will want to leave in your camera bag.
1. Filters (Polariser, ND, GND, UV)
Filters are a great way to shape your available natural light and there are many different kinds. The most common ones used for landscape are the polarizer and the graduated neutral density filters.
Polarizer / Circular Polarizing filter (CPL)
Some landscape photographers never leave home without this accessory. The major pros of CPLs include the way they enhance your colors (think blue skies) and also cut glare/reflection. In contrast, there are situations when you will not want to use a polarizer.

Neutral Density (ND)
This filter is basically a darkened piece of resin/glass that reduces the amount of light that enters your lens. Furthermore, in a proper ND filter, the color of the light is not affected (neutral). It is most useful in bright conditions, where you want to use a longer/lower shutter speed or wider aperture. ND filters come in different increments, which vary the amount of light that you block.
