You can always use usual cleaning tools like Clone Stamp and Healing Brush. However for product photography I like to use Photoshop Filters and Masking. Let me show how I do it? Below you can find the simple steps:
1. Open the image and Duplicate Layer

This is 100% crop of the cosmetic brush image
2. Go to Filter/Noise/Median…
For this particular image I’ve choose radius 13. But you drug the slider until all small dust disappear.
3. Filter/Noise/Add Noise(Gaussian, Monochromatic)
Amount 1.5%
4. Filter/Blur/Gaussian Blur
Radius 0.5

Median 13, Noise 1.5, Gaussian Blur 0.5
5. Create Hidden Mask Layer → Layer Mask → Hide All and paint over the object to clean dust and even borders. Do not paint all object, only areas you want to clean.
This is the final result:


This is another example:
Median 9, Noise 0.7%, Blur 0.5


Try it! It’s really fast and easy:-)
Best, Genia.

Thank’s for the tip
That’s useful.
Great tip! Do you have a lesson like this on how to fix/remove/blend reflections in metal and reflective surfaces?
Like when there is a reflection in the band of a ring and you want to make it look like just the metal with natural
gradient. Thanks for any help..
This is awesome…less time on post processing and more on shooting. Thanks for sharing.
Nice, Andre. Just clean it, and will be perfect:-)
Thank you. I’ll do such tutorial. And we plan to write a book about jewelry in couple months.
Very nice tip. I found it via Alex’s post on google+
One question though. The add noise filter doesn’t have a radius setting (at least in PS CS5) did you mean percent: 1.5% rather than radius 1.5 ?
Thank you!
Yes, of course, I mean Amount in %, not a radius. Thank you for correcting:-)
That’s a very useful tip, thanks. I thought you’d lose detail but it looks great.
Now I have to ask where’s that ‘clone stump’ tool you mention, cos I haven’t got one of those!
Sorry, Clone Stamp.
Hi Genia,
REALLY. COOL. TIP.
I do some shoots of black diamonds with rings at the moment and that will definitely save me hours of retouching!
Thanks. Really!
Greetings

Thank you Genia for this wonderful tip! This is going to save me so much retouching time for my product work. Thank you too for all the information you and Alex share, your generosity is much appreciated.
That is amazing. I wondered how all the objects (jewelry, etc.) looked so flawless in the images.
