Since I took so many shots yesterday, I feel compelled to post another one to try and justify it all. Yesterday, my intention was to get a shot that utilized the variable ND filter that I bought. I did take a number of shots with it – this being the one that I feel is the winner.

For those that do not know, an ND filter is something that you put on the lens to reduce the amount of light coming in. This allows you to make a bright day seem darker, but also more importantly allows you to use a slower shutter speed when it is bright out. The common case use for an ND filter is to get motion blur, such as with moving water, which requires a shutter speed in the seconds. ND stands for neutral density and you can buy them as only one setting – such as a 3 stop ND filter which would block 3 stops of light. A variable ND filter is just one filter that allows you to adjust the brightness by twisting it, to allow more light or reduce the amount of light. While this sounds like a better way to go, there are issues. The primary issue is what is called a crisscross pattern. This crisscross don’t make you jump, but rather causes one section of the image to be brighter than another. From my experience yesterday, yes – it is a problem. With the image above, I had to do a little editing to brighten up some of the corners due to crisscrossing. My research says that this is most common when using the maximum setting of 8 stops which is what I used. I am hoping my next experience will be better, but either way it will still be a good addition to the kit.

I used my Canon 7D Mark 1 with a Canon EF 24-70mm F4 L lens at 24mm, shooting at 2 seconds, F22, with an ISO setting of 100. It was a very sunny day when the shot was taken.
