Killer Dust Bunnies (BEFORE/HELP or AFTER)

You're shooting and swapping lenses as needed -- the stuff you saw in the finder looked great. However, when you look at the images on a bigger screen, you notice that this huge hunk of dust settled on your sensor just before you took your best shots. This challenge is for photos "ruined" by sensor dust (marked BEFORE in title) and how they were saved in postprocessing (marked AFTER in title). Entering an image marked HELP in the title invites others to postprocess and submit AFTER versions of your image.
