Visualise spots: Reveal dust spots in Capture One

Quick Tip: Dust Spot Finder in Capture One: reveal and remove them

Capture One just got a new exciting update, a dedicated before and after tool, and a new powerful Heal and clone tools Faster and easy to use. before this update, the healing and cloning tools were unusable to me, but now with this update, I can save time from moving back and forth between capture one and photoshop.

As landscape photographers we spend most of our time shooting in harsh conditions and changing lenses outdoors, because of that we get a lot of dust spots on our camera's sensors, the best way to get rid of them is by cleaning the sensor regularly, but if you forgot to do that before a shoot, we can remove them easily in Post-processing.

Before start removing the dust spots we have to find them first, as it can be difficult to spot them especially in low contrast areas, And Capture One still doesn’t have a Visualize Spots mode Like Lightroom. I am gonna show you a trick that Will allow you to see all the dust spots, using a combination of contrast, clarity, and structure, and saturation.

Step 1: Create a new Heal or Clone layer

This layer we gonna use to remove the dust spots.

Step 2: Create a new filled adjustment layer

This layer we gonna use as the dust spots finder.

In this dust finder layer, we gonna lower the exposure slider a bit, and crank up the Contrast, Clarity, and Structure all the way. I also desaturate the image as Colors can be a distraction as well. the goal of those adjustments is to increase the contrast which will help reveal all the spots on the image.

After making Those adjustments we made the image look horrible, but Now we can see all the dust spots Clearly.

Step 3: Remove the dust spots

Now go back to the dust spot removal layer and select the healing brush tool you can also use the keyboard shortcut ‘Heal Brush’ (Q) and ‘Clone Brush’ (S).

HEALING

With the Heal brush tool selected start clicking on the area, you want to remove, capture one will try to find the best suitable source point to heal the area you selected. Capture One will display the chosen source, so you can move the source point freely if you are not happy with what Capture One selected for you.

Sometimes capture one will not display the Selected source because it thinks it has found the best source so you won’t be able to move it, If that happens you can force capture one to show the arrow by just holding down (Option / Alt) and clicking on your preferred source point.

To delete any healed area just select the source point and hit the (backspace) key. Or you can use the Eraser brush. There is no limitation number on how many healing strokes you do on one layer.

CLONING

To use the clone brush tool you need to set a source point that you gonna clone from first, set a source hold down (Option / ALT), and click on the source you want. And then start brushing. With the cloning tool, I recommend that you use a feathered edge brush, by lowering the hardness slider to the left, to make the cloned area blend seamlessly without noticeable cloning edges.

To delete a clone area you need to select the source point then hit the (Backspace) button. Also with the clone tool, there is no limiting how many cloning areas you can have on one layer.

HEAL AND CLONE BRUSH SETTINGS

To invoke brush settings you can click on the icon in the layers tool or right-click when the brush is selected.

Brush Size: to control how large the brush is you can move the slider left or right, also you can use the keyboard shortcut the square brackets ("[" and "]"), left square bracket to make the brush smaller and right square bracket to make the brush larger.

Brush Feather: with the hardness slider you can control how hard or soft the brush edges are. you can also use a key shortcut which is the Shift + square brackets ("[" and "]"), shift+[ to make the brush softer and shift+] to make the brush harder.

Here is the before and after removal of the dust spots with heal and clone brush tools.

Delete Selected layer

After you have removed all the dust spots, now you can just delete the Dust finer layer as we don’t need it anymore. Or you can save it a Capture One style so you don't have to do those steps every time you need a dust spot finder layer, also you can download the one I have made.
