ND filters are a common piece of equipment that can dramatically improve the quality of long exposure photography. They are typically used to add a blur to water and clouds, create more of an abstract look and remove moving people from the scene.
There are many different brands and types of ND filters on the market, and each one has it's own benefits and drawbacks. Some are very expensive, while others are affordable and still perform well.
One brand that has recently become very popular is Breakthrough Photography, who have a reputation for being thoughtfully designed and well made. They also have a great price point, which is ideal for those who want to get into long exposure photography on a budget.
The first thing that you will notice about this filter is the quality of the glass. It is very durable and does not have any noticeable color casts or tints. This makes it easy to use even in bright sunlight. The filter is also very light in weight, which means you won't have any issues with it weighing down your camera.
Another benefit of this filter is that it comes in a variety of lens thread sizes. This allows you to use it with your existing lenses as well as future ones that you may acquire. It also comes with a protective clamshell case to keep it safe from scratches. The ring that the ND filter is attached to has all of the different stops written on it, which helps when trying to find the right setting.
