Another excellent article from digital Photography School, about how to remove dust spots from your photos. I’m going to need to try this out on my own photos, especially after that full day of shooting with a dirty sensor (see the before/after examples here: https://blog.wolffmyren.com/2008/07/07/before-cleaning/ and here: https://blog.wolffmyren.com/2008/07/07/after-cleaning/)
Dust. The eternal enemy of a digital camera. When you shoot pictures with a digital SLR camera long enough, you will come to know the pain that dust can cause. For some it’s a minor annoyance. For others, it costs time and money attempting to salvage vital images.
In this post Peter Carey shares some tips on how to remove dust spots from multiple photos.
With advancements in DLSRs has also come advancements in Photoshop tools to remove dust. My favorite for dust removal, partially because of its price, is Photoshop Lightroom. While it is a scaled down version of the full blown Photoshop, it is perfectly suited to remove 90% of the dust I encounter.
Why is dust such a problem? Take a look at the picture on the left. Do you notice the small black spots in the sky and one big spot on the left side in the mountain? Those are not UFOs and that is not a mining tunnel. It was dust adhered to the sensor, casting a black shadow on the sensor when the shutter was activated. You can’t get back the data that is covered over by the shadow, but you can get creative and repair the damage depending on the dust location. When those dust spots are in the same location on each image, you’re in luck as there is a fairly easy method for multiple photo dust spot removal. (Note: the instructions are given using a PC version of Lightroom 1.4. Mac instructions vary only slightly if using a single button mouse)
