Noise in form of black dots

[Roy2100]

Hi

Anyone have a problem with noise in the form of black dots when shooting night shots lit with a street lamp while using a d810 at ISO 4500 f2.8, 1/100?
Not sure whether you can see the dots on her face, which is my main concern. Noticeable in Lightroom and when printed, but not so much in photoshop. Also the photo posted darker than what I printed.

Anyway, you thoughts are appreciated.

I zoomed in as much as possible but the file is too small to show much detail but from what I see, all the pixels in her face are natural tones, none is black or excessively dark.

What I do see at pixel level in other parts of the shot are color variations that shouldn't be there. If I'd have to guess I'd say they're low light noise multiplied by the ISO.

Here's the face I see at pixel-size.

You are going to get noise at ISO 4500. Did you apply Lightroom's Noise Reduction? Zoom in on her face and move the slider to the right. Keep watch to see the changes. Noise Reduction can soften the image which is why I suggest zooming in when applying it.

Did you lighten any shadows? That will also increase your noise.

I think you are asking the impossible out of your camera

Welcome to the forum. Scott may be right, but that's also pushing the boundaries and seeing how far you can go. Just don't be disappointed if it's pushed too far.

It's indeed worth experimenting with although those settings mentioned are a bit demanding if one wants noise-free shots. You'd need an awful lot of light during night shots for that to happen.

Welcome !

You will get noise on night shots at this ISO level on just about any camera.
Need to lower your iso and use a tripod, when shooting night images with no movement in them.

If you want to capture moving objects at night then you have no option but to use higher iso and accept noise and then try and remove in post processing.

Thank you for your rely J-see. I'll post a cropped image of the woman. Maybe that would help. I appreciate your efforts to help me resolved the ugly and I do mean ugly noise problem.

Hi Hark
Thank you for your reply. Yes I used Lightroom's noise filter on the image. It didn't work. I'm thinking that the noise generated by the high ISO combined with the dark exposure is not normal. Yes the image will have noise given the way I shot the scene. But not the ugly larger than a gain of sand noise the camera produced. I'm going to upload another but large image focused just on the woman. Maybe that will exposed better what I am asking about.

Hi Scott, Mikew. Thank you for your replies. I expected to get noise, but not the large, unresponsive to noise adjustments in Lightroom the camera produced. Think drops of black ink. Those ink drops are on the image. I don't believe that's the type of noise that is typically generated.

 

[Roy2100]

Thank you Marilynne.

Thanks for responding Dave. I' worried that the noise my camera produced is different than the noise one would typically see at the setting I used. I thought before I contacted Nikon I would run the problem pass you guys. I am going to post an image that shows what I am talking about. It's not the grainy sand like noise we have come to expect with the setting I used. This was more like drops of black ink. I don't think that's right.
