De-noise software

[cloudbuster]

Hi all.

Just wondering if you would help me?

Is there any software tools in either photoshop or lightroom for reducing noise?

Cheers

No idea, but try free GraXpert 3 on your linear data. It has AI gradient removal and AI noise reduction. I think it's brilliant.

If you've used them you'd know they do. I've found them not very useful for astro though, the colour noise reduction is okay for reducing that type of noise. The suggestion above is good, or download and install Gmic plugin for GIMP (free PS alternative), it has a few more aggressive NR tools. But as with any NR, use it subtly, an image devoid of noise looks "unnatural" and aggressive NR will generate abberations.
