When shooting outdoors in the sunlight, you’ll often need to use a very small aperture/iris setting to get the right exposure. That is not necessarily an issue unless you want to blur the background to draw the attention of your audience to your main subject. This is where a neutral density filter can help. A neutral density filter is like high quality sunglasses for your camera’s lens. This allows you to use an aperture setting which will blur the background and still allow you to expose properly.
Aurora Aperture was kind enough to send us their Power XND 2000 variable neutral density filter for review.
