Today I thought I’d share a technique with you that I now use on every single picture that I edit, 100% of the time.
It’s a technique that I was reminded of by Scott Kelby during his recent trip to London and it’s for checking for those pesky dust and oil spots in your photographs that come from off of your camera’s sensor.
Until recently I used to go to the 1-1 view in Lightroom and look around for these marks but there would always seem to be one or two that escaped capture. However with this technique it’s a totally different story…the specs of dust and oil may just as well be waving White flags in surrender
With just 4 simple steps the technique couldn’t be simpler:
Step 1: Duplicate the background layer
Always work on a copy of your image just in case you go wrong somewhere along the line and save what you’ve done. You can duplicate the main image (Background Layer) by:
- Click, Drag & Release the Background Layer over the ‘New Layer’ icon at the bottom of the Layer Panel, or
- Press CMD (Mac) or CTRL (PC) + J
Step 2: Invert the image
Invert the image to get this ‘X Ray’ looking view by:
- CMD (Mac) or CTRL (PC) + I, or
- Go to IMAGE > ADJUSTMENTS > INVERT
Step 3: Remove the dust spots etc…
Inverting the image can make any dust / sensor marks stand out so that you can see them clearer. All that needs to be done then is to remove them by using your tool of choice e.g. The Spot Removal Tool
Step 4: Invert the image
Now that you’ve removed all the visible dust / sensor marks you just need to Invert the image back to it’s original state by again pressing CMD (Mac) or CTRL (PC) + I and you’re done, leaving you to carry on with any other editing:

And that is all there is to it. Of course the easiest way to not have dust spots on your sensor is to to keep your sensor as clean as possible but as we all know that is easier said than done; especially when working on location.
