Sometimes a photo can have an excessive amount of dust and scratches, depending on the environment where it was shot. Knowing how to use filters instead of repairing an image by hand can make for less work in the long run. Here we have a shot of the watch that we've been using before, and I want to first crop out the excess areas and concentrate on the image itself. But also, I have a lot of dust going on throughout my entire image here, and I want to try and clean that up. Now I could go through and use the healing tools and try and touch this up, but it's a lot of excess.
So instead, I'm going to try and achieve this using the dust and scratches filter. So to crop this, I'm going to use my crop tool and again, keeping things non-destructive, I'm going to uncheck Delete Cropped Pixels up at the top of my control panel. As I go through and crop this, I can achieve this by just hitting enter or return. With Delete Cropped Pixels unchecked up above, my canvas size crops, but not the image area. To re-crop this, I simply have to go back to the crop tool, hit Enter or Return, and my entire image shows up and I can re-crop.
Now, keeping this non-destructive, I want to make sure that I'm also not working on my original layer. So on Layer 0, I'm going to duplicate this layer, and I'm going to double-click and I'm going to rename this Dust. This is the layer that I'm going to use a Dust and Scratch filter on, to try and remove all the little specs in my background. To achieve this, I'm going to go to Filter > Noise > Dust and Scratches. Now there's two options here, I have Reduce Noise, and Dust and Scratches.
Reduce Noise would work if I have noise created by adjusting for color and shadows. But you can see as I go through it here, even as I increase my strength, it's not really getting rid of all the little specs in my image. So instead, I'm going to go to Filter > Noise > Dust and Scratches. And what this allows me to do is go in and adjust based on my background. Now, my radius will adjust the overall blur radius, and my threshold will give me a break between light and dark.
So I'm here as I'm adjusting my threshold, the higher I go, the more of the image I see, the lower I go, the more the image will become blurred. So balancing this out I can get a good balance between. Now, be aware that this is running across the whole layer, so my watch is also going to be deblurred. So on here, I'm going to go through and add a layer mask by clicking the Add Layer Mask button at the bottom and taking my eraser tool and my stylus, I will be able to erase and bring back in the detail around the watch, preserving that, and also keeping my background free of dust and scratches.
