p.1 #1 · Pixel map stubborn dust (5d2)


Can Photoshop (CS4) pixel map out a stubborn dust bunny?

If not, what software (free?) is recommended?

thanks

DPP has pixel mapping of dust bunnies and it is free. You shoot a white sheet and record it. Then DPP adjusts it for free. The downsides are:
1) Then you have to introduce DPP into your workflow
2) Needs adjusting when new dust arrives or dust moves

Why not just clean it. I do it all the time and it takes 15 minutes, which is about the same amount of time, to set up either Cs4 or DPP.

I can't recommend a free software fix, but if you find yourself using Lightroom, you can remove it with the clone tool, make a preset out of that, then apply it to all the images.

Just remove the stubborn dust with a sensor swab & the highly refined methanol liquid.

I have to clean my sensor with a swab on rare occasion.

good suggestions, all.

until I get to cleaning the sensor the right way, I just made an action (clone and healing don't record, so I just took a small sample next to the offending dust, feathered, cut, paste, flatten). did a separate one for vertical and horizontal.

rudimentary fix for now and not 100% perfect, but speeds up workflow tremendously.
