It’s been a couple weeks since I’ve gone out to photograph and today with the sky overcast I thought it would be a good time to head back to 50 Point Pier for some moody photos. I brought along my 10x ND filter to get my experiment on.
ND or neutral density filters are like sunglasses for your camera. The filter can be either screwed on to the front of your lens or it can slide in front of your lens with the help of a filter holder (sold separate from the filter, lens or camera). When placed on the lens it reduces the amount of light getting in to your camera’s sensor.
There are different densities of filters. Some are only slightly tinted while others are more tinted. The different levels of tints allow you to shoot slower shutter speeds or open your aperture depending on what you are looking to accomplish with your photos.
Why would you want a longer shutter speed? When allowing your shutter to be open longer anything moving in your scene will essentially smooth out as shown in the photograph below.
You’ll notice in the photo above that the colours are very different from the photo at the very beginning of this post. ND filters are supposed to be a neutral grey colour, however, they usually tend to have a little colour in them. This colour becomes more prominent when shooting a long exposure. You will notice the one I use shifts the colour toward a more purple shade. This is because there is a little purple in the grey tone of my filter.
One way to get rid of this colour shift is to create beautiful black and white images. Of course, if you are shooting in RAW you will be able to adjust the colour in your post processing to create the look you want.
Photography is all about experimenting and having a little fun. Most people don’t usually have a 10x ND filter but have one of the more common ones like a 3x or 6x. You are the artist so you decide which one works best for you.
