This should work for you:
- Use a tripod or at least a mono-pod as you shoot at very low speed 1/8.
- Exposure: Use manual exposure to get the right settings for the picture.
- Focusing: Select a brighter area that you want in focus*. Have the auto focus do it's job. Depress the shutter half way and keep it half depressed. If you use 3D tracking, disable that first.
- Compose your picture and depress the second half.

Most DSLR have this 'shutter feature'.

When you still have too much noise, use the blur ONLY in the dark/diffuse areas as the blur is nothing more than a gimmick that removes sharpness over all so PP with care.

* Auto-focus works better in bright areas. Many times when a picture is not in focus it is because there is a brighter area in the picture and the auto focus locks onto that area.

NOTE: Photo Element is a superior editor than Lightroom. It also has the blur feature and it can be selectively applied by using layers and/or masks.

Hmmm, ok, interesting. Which Photo Element do you recommend?

Cawanua, I agree with the others, your part of the photo is really nice. The camera was being asked to do more than it is capable of. A couple of suggestions (in addition to those of others)

First, Elements is just fine for what you are doing. In fact it is fantastic for working with your night shots.

Second, since you like taking night shots and have Elements:
A trick I read about a while back and tried out myself (because I was getting too much noise in night shots) is to take multiple images of the same scene and use photomerge in Elements. You can do this with the same exposure on, say, three tripod shots or with bracketing as suggested above. Because noise is random the little spots won't be in the same spot an all images and PhotoMerge will blend them. (Of course, with moving objects you will have to mask those so only one image uses them.

And, invest in DeNoise which works as a plugin in Elements, You can get a 25%-30% discount if you look around or call them and ask for it. I can tell you more on this if you want to get it -- PM me.

Third, if you find that you have to manually focus there are Apps that can help you calculate the correct setting of the 1/3 - 2/3 rule mentioned above.

This past Saturday, I took this shot during a heavily overcast evening with low clouds. I used a Nikon D 90, a Sigma 70 -300 lens, and tripod. The cameral was set on a timer to release the sudder.

I used apeture priority with 400 ISO. What could I have done differently to get a better, less noisy picture.

By the Way, this is my processed version.

Thanks for checking this out for me.


I like the noise! I think it adds to your very nice shot. I think you should leave it in.

I think the noise is because your shot's lighting is extremely difficult for your camera's sensor to interpret. there are a lot of similar shades (fog) that their differences are too subtle for your camera to differentiate. Did you shoot this photo in RAW or Jpeg? Next time try overexposing the shot one stop, then bring your exposure down in post editing. This may help you reduce the noise. I hope you are shooting in RAW.

I really like your photo as is.

Thank you, I'm happy you like the picture. I do shoot in raw and it is easier to darken in RAW than to lighten. Over exposing by one stop is a very good idea.

Another very good idea. I haven't tried bracketing yet but It would appear that surely need to try it. Thank you so much for your suggestions. I appreciate it.

Minor correction (been a while since I did this). You use the transparency slider on each layer not the Merge to reduce noise.

Use a tripod that will help. In low light settings you are generally at lower exposure so even if you have IS you can still be out of focus unless you are really quite with hand holding the camera.
