Dust and scratches are a thing of the past thanks to Adobe Photoshop.
You Will Need
- Adobe Photoshop
- A dusty, scratched photo
Step 1: Decide how bad it is
Decide if you have just a few things to clean up or if your image is in serious trouble. If you’ve got a few pesky scratches, go to Step 10. If you’re looking at a more general mess, continue with the video.
Step 2: Correct contrast
Correct the contrast in the photo by going to Image, then Adjustments, then Auto Contrast from the top menu.
Step 3: Open Dust Filter
Open the Dust and Scratches Filter dialogue from the top menu by choosing Filter, then Noise, then Dust & Scratches.
Step 4: Select Preview
Select the Preview option.
Step 5: Set Threshold to 6
Set the Threshold option to 6 as a starting setting—you’ll likely adjust it later.
The Threshold tells Photoshop how different a set of pixels needs to be in order to activate the filter. The greater the Threshold, the more different the pixels must be.
Step 6: Change Radius setting
Swing the Radius option around and look at the effect.
As you increase the radius, Photoshop increases the distance in pixels it will apply the filter from any identified blemish.
Step 7: Adjust Threshold
When you’ve settled on a Radius setting, dial the Threshold back and forth until you’re happy with the result.
Step 8: Make sure you're happy
Step 9: Select Clone tool
Now that there are just a few blemishes left, select the Clone tool (also known as the Rubber Stamp).
Step 10: Choose details
The brushes option will appears at the top: Select a brush size, hardness and opacity.
Try a brush with a diameter about twice as wide as the blemishes you’re trying to fix with a hardness no greater than 80%. Experiment with the opacity.
Step 11: Sample area
Sample an area that’s similar to the area you’re patching over by holding down the Option button on a Mac or the Alt button on a PC and then clicking.
Step 12: Fix area
Release the Option or Alt key and click and hold as you move the mouse over the area you’re fixing.
Step 13: Continue to other repairs
If your repair looks good, continue to the next repair. Otherwise, Undo and try again.
The Healing Brush in Photoshop is a more advanced alternative to the Rubber Stamp/Clone tool, used for more subtle corrections.
