Tiffen filters are the best option for outdoor landscape work. One half of the filter is a 2 stop ND while the other half is clear with a soft edge between. The filter is mounted in a rotating ring like a polariser so that the edge can be aligned along the horizon. They are perfect for landscape work where exposure is always a compromise between an over-exposed sky or an under-exposed foreground.
They come with Tiffen's 10 year workmanship warrantyColor-Grad? Neutral Density Filters
Often, you want to balance light intensity between two areas within a scene. This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark, underexposed.
- Part clear, part neutral density, with a smoothly graded transition between
- A Color-Grad ND.6-to-clear is often best for balancing sky to foreground
- Neutral gray appearance drops exposure
