Digital photographers may not have scratches to deal with, but dust spots can be a big annoyance. In that case, post processing solutions like photoshop can be the saving grace for dusty shots. Some film scratches repeat themselves, but it is certain that dust will affect every shot unless it is removed or unless the photographer compensates for that dust.

Digital SLR users should be aware of all their options to adjust for sensor dust, both pre and post shoot. There are some techniques here: http://blogs.adamparkerphotography.com/blog/Ive-got-sensor-dust-what-should-I-do/13/

Thanks for reminding us all that sometimes the simplest tools for processing our pictures are the best.

Forgotten Photoshop Filters: Dust and Scratches…

Dust and scratches aren’t a huge issue with digital photos, but film scans can suffer badly. Here’s a good explanation of a Photoshop filter that can help out….

And one more way of doing things – I scan my 4×5′s and used to spend a fair amount of time dust spotting. Now I make a duplicate layer above the background layer, and run the dust and scratches filter on the duplicate layer, using the methods described above to get rid of the worst of the dust spots. I then add a mask to the filtered layer and fill the mask with black. Then simply take a white brush to the mask above the individual dust spots – you can tune the brush size to fit the spot. For larger spots (e.g. somehow I always get a piece of cat fur in my scan) – I simply clone it out on the background layer.

I still spend more time than I’d like dust spotting (i.e. more than zero), but this is the fastest method I’ve come up with.

Cheers!

here’s another why of doing it too (not my website, but found it acouple days a go and really liked it)….. http://www.sjphoto.com/newsletter_april_2004.html#anchor

Real Image Dust Removal

1. Duplicate dusty file by dragging the image layer to the page icon on the
layers palette.

2. Turn viewing off for the top layer, then select bottom layer

3. Run a fairly aggressive Dust and Scratches filter on the bottom layer,
careful to make the Radius large enough to get most of the spots you need to
lose, but then dial the Threshold up to as high as you can to bring texture
back, but not undo your dust removal.

4. Turn viewing back on for the top, unretouched layer, and then select it
as the active layer.

5. Use the Eraser tool to erase your dust spots on the unfiltered top layer.
This will let the dust removed layer show through from underneath. Brush
will likely need to hard-edged to not blur grain.

6. Flatten layers when done.

Here’s another quick tip for using this filter since I’ve used it A LOT!!! Make small selections instead of trying to do the entire photo. I don’t know why but it will work much better. After you have made your selection and hit OK, move your selection to the next area and press “control + F” and it will redo the filter. You can do this very quickly, much faster than redrawing your selection over and over.
