No matter how much I clean an object before a shoot, I usually discover afterwards I missed some dust after I start to process the image in Adobe RAW. Fortunately, for me Photoshop has a built in dust rag.
Were about to embark upon a technique I have used hundreds of times, and only now am I revealing it for the first time. Were going to make all those dust specs History!
First well need to go to the filters menu:
Noise>Dust & Scratches
Then well pick a piece of dust to use as a gauge to adjust the Radius settings.
Move the Radius slider till the piece of dust just disappears, then increase it by one. In my case, the dust disappeared at a setting of 3 so I increased the setting to 4.
Next well want to increase the threshold to bring back any texture we might have washed out adjusting the Radius. Enough so the texture (if any) begins to appear again but not so much the dust begins to appear again.
Now for the History part of this tutorial. Were going to take a Snap Shot of layer for latter use. In the history palette, click the middle icon to take the Snap Shot.
(Smile : )
Look closely now at the top of the history palette. You will see a new snap shot created for you. Click the box to the left of the snap shot to make it active.
Now we go back into history when we first opened our dusty dirty image. Click back to BEFORE we applied the Dust & Scratches filter.
Choose the History Brush. Set the blend mode to darken, since our dust is lighter than our background.
Now brush away all the dust! - Photoshops Dust Rag!
