If you have done research on this piece of gear, you may have found an overwhelming amount of information and options.  This write-up is designed to clarify what the best options are for you.


Graduated neutral density filters are offered as both circular filters, which you can screw onto a lens, as well as square filters which can be held or used with a filter holder.  The circular graduated filters forces you to place the graduated line half-way through your scene, most of the time this is not where you want your filter position for the best composition.  Be sure to get the square graduated filters!  This will allow you to use these filters with any of your lenses (with the exception of lenses with a bulbous piece of glass), regardless of the filter thread size.  


Graduated neutral density filters are offered in both "hard edge" and "soft edge" versions.  Both have their own place.  Soft edge filters are used in areas where your horizon line is not completely flat (mountain scenes, horizons with trees sticking up, really anything that is not 100% flat and clear).  Hard edge filters are only used for completely flat horizons such as the horizon on the ocean, or a field in Nebraska).  Having a soft-edge graduated neutral density filter is one of the best tools that you can have in your bag for landscape photography.  Don't worry about not knowing how to use it, we are active teachers in the field during all of our tours, customized to your needs and learning style.  


These are the brands that we would recommend.

This is the least expensive option for filters that we would recommend.  These, like some of the higher end brands, are constructed of resin.  This is our go-to choice for an entry into using graduated filters. Resin filters can scratch easily.  Although the price is far less than the higher end brands, these produce very high quality results at a much cheaper price.  

There are two major drawback with this filter set however.  If using the filter holder which comes with this set, along with your lens at its longest focal length, you actually see the filter holder in the image.  This means in order to use these with your widest lens, at it's wide end, you must handhold the filter.  This is our standard approach typically, but can be problematic when using very long shutter speeds.   The second issue is that these filters scratch quite easily.

The LEE Filter system is the industry standard for landscape photographers.  These, like the Cokin brand are constructed of resin.  The benefit of this filter set over the Cokin series is that it gives you the availability to use these filters at the extreme wide ends of your lenses with a filter holder, rather than having to hand-hold the filter up to your lens.  Overall qualityj of the filter is great, and it does produce slightly better results than the set referenced in the Cokin set above.  A big plus to this set is that they are a bit more resistant to scratches than the Cokin set, but are not as resistant as the Nisi set below.
