ND Filter Question

Here are two shots with a D7000, 18-200mm. The first is with a Green.L (brand name) ND4 filter, and the second is without a filter. As you can see the first (filtered) image is darker.

I shot at shutter priority 1/80. With the filter, the camera chose f/5.6, and without a filter, it chose f/10.0.

I don't like the looks of the ND4 image. Bad filter?

With filter, 1/80 sec, f/5.6
With filter, 1/80 sec, f/5.6...

Without filter, 1/80 sec, f/10.0
Without filter, 1/80 sec, f/10.0...

It looks to me like the filter is doing what it's supposed to do but I agree with you in that I personally like the shot without the filter better primarily because of color, clarity differences! :wink:

Yeah, there is a definite color shift.

From what I have understood the ND filters are used to attain a slower shutter speeds in bright conditions to blur movement. I've only seen them used in manual mode to set the apeture and shutter speed.

That's the way I understand it. I wanted to see if there was an obvious difference between the images with and without the ND. I'm not happy with the filtered image. Aside from the filter, the only change was the aperture opening up 4-5 stops. I had expected the two pictures to be almost indistinguishable.

Just curious-what was the reason for using the filter for this shot? It might be a good filter for an exposure that really requires an ND filter. In these pics I definitely prefer the the unfiltered flavor.

It was a test, and I wanted to see what others thought. I don't think I'll be using this filter.

Why not try aperture priority? The sharpness may be due to smaller aperture.

i dont think you really understand when to use a nd filter. if you look in the top right hand corner of the photo you took with the filter,you will see how the filter has done its job, by making the sky blue, instead of being washed out like it is in the second photo. filters in my opinion, are good but have to be used with consideration. hope this explains a little.

Jerry, try photographing the cloudy sky with the filter on and off. The clouds will pop a lot more. Filters are used for a reason, no reason for the shot you took. Close the aperture down to about f/22 and shot a water fall at 1 second and see what you get. It's meant to give you longer shutter speeds to get the affect you want. Try using the filter for what it's meant for before you throw in the hat. Have fun with it.
