Hi all,

I have the Adobe CC package and I've taken a few pics where the bg could do with with having the noise dealt with and leaving the subject without any NR.

Is there an easy way to do this in LR or PS?

When I type background noise reduction into Google, all I get is how to remove it from audio files!

Any help will be appreciated.

Many thanks,
Wez
 
In LR import photos then along the top bar go to develop. A tool bar will pop up on the right if you scroll down the noise reduction slider is under sharpening. You have a little preview screen as well.

Move the slider to the right to the required amount which even at high ISO never seems to be more than 20 or 30 on my shots.

Hope that helps.

In ACR you can brush NR in on the background,then the same area you have reduced noise in you can adj sharpness down or exposure up or down if you wish.

Thanks for the quick reply! :)

Appreciate the help but I wanted to know how to NR just the bg and not all the image (y)
 
You can use the brush tool in Lightroom, assuming you're not on an old version of the programme (I forget when they added it).

In the Develop module, hit K on your keyboard to bring up the brush (or select it from the icons under the histogram, the brush is the right-most one), and then start painting.

Depending on the image, painting in manually in LR can be a pain. Auto-masking is pretty good though. This video will give you the basics on how it works, I thought it worked differently than it does at first, so handy to understand.

I saw a shorter version of it in the past I think. The bit with the white aspen trees should tell you all you need to know, from around 2 to 4 minutes in this video.

I always go to PS from the "Edit in PS" option once I've done basic adjustments in LR.

ACR never comes up, only if I open the file from scratch. I imagine the PS tools are the same as ACR?

Thank you for the link.

I've tried brushing it in before in LR (I have the latest versions in the CC package) and it takes quite a while painting it in manually.

That tip with the trees is very handy, thanks, will give it a try :)
 
In photo shop go to the filter drop down and select camera raw,you can go back and forth as much as you want.
 
Some times if you go to the select drop down and choose focus area your bird will be selected,then inverse selection and you can work on just the back ground.
 
If its for wildlife, i generally use the Radial Filter tool and draw roughly around the bird, hit the "Invert Mask" button, and hey presto, 90% of the background is selected, if you want to be a bit more specific you can then hit the brush tool button (just below the Radial Filter button) and add/delete bits of the mask to suit

Much quicker than painting the whole thing in by hand

Get the now free Nik package (plugin) and use Define in brush mode :)

That sounds like an interesting way and will certainly try it out and see how I do :)
