Denoise or not denoise that is the question

There is only a slight difference between the two, but #2 has gone through a noise removal, while #1 hasn't.

Is it worth the effort?


The bird is ruddy stonerturner, the shot ISO 1100, 1/3200 F6.3 @ 1/3200 sec. Tamron 150-600@600mm.

You need to revisit your technique and / or tool. The white of the bird wasn't cleaned making it a questionable result / effort.

Technique involves removing the denoise blur (history brush) over the subject, keep the subject as sharp as possible

I tried several times to correct the bird id, but it didn't take.

The bird is a ruddy turnstone

A noisey subject against a clean background is not the desired result. The EXIF is stripped, what camera and ISO was involved?

Are you using Lightroom? The WB dropper would correct this quickly.

The colors are nice and unless zoomed to 100%, the cleaned version is nice too. For cleaner results, you might consider shooting in RAW and at a lower ISO for this model and / or forcing the exposure to the right where the whites come cleaner from the camera before processing. If using Topaz Denoise or similar tool, consider their video training on advanced techniques to clean white and retain details. Ideally, the closest bird would be as 'clean' as the background, where this version looks like there was a mask over the bird and it didn't get cleaned as well as the image overall.

It was shot raw, I trued stepping the up exposure didn’t help, white lost fine detail long before the noise quieted. Keeping down looking like down critical

Do you have Lightroom?

This was shot RAW, the technique for cleaning noise was:
Load the RAW file into Photoshop
Launch Topaz DeNoise 6 plug-in
Apply DeNoise heavily to the entire photo
Return to Photoshop
Use the History Brush to remove the Denoise blur from the subject
Use adjustments, Camera Raw Filter, etc as appropriate.

The expectation is the the subject will be as sharp as originally shot, while the denoise blur would blend with the out of depth of field blur

Try instead cleaning with DeNoise after all PS / LR adjustments and see if you get better results. Pass the file to DeNoise as a 16-bit TIFF in colorspace ProPhoto RGB and return the processed file in same TIFF format. But, save cropping for post-DeNoise. That is, don't DeNoise before cropping, especially heavy cropping. Make a virtual copy of a cropped image and remove the crop to send to DeNoise. Use Sync to reapply the crop from the VC after importing the processed results into LR.

For the final version, I put the subject birds breast in shadow (darkened with S curve), cropped the foreground.
I think the technique dealing with noise works, but if a large portion of the subject is bright, you still have to deal with the noise another way.

Thanks for all your help.
