Anyone know of a way to get rid of/minimize dust particles while staying within the boundaries of the Basic Challenge?

The NeatImage route is one option, but applied aggressively enough to redue/eliminate dust spots will result in a "plastic" look and loss of detail.
Hiding the dust through added noise (legal in basic) is another dubious solution.
The best you can do is try to minimize the appearance of the dust through control of saturation and contrast (don't increase them so far that you emphasize it).

Isn't Photoshop's DustAndScratches filter legal? |

Yes, but the results are awful, a bit like NeatImage way over-applied.

Maybe that's why I never use it : )
Does it help to Fade the effect? |

Dunno, never tried it. Looked so ugly after intially applying it that I ran screaming.

is it legal to clone out small particles in basic challenge

No. That's considered spot editing.

Same deal. That's also spot editing. Any time you are applying something to only part of an image it is not allowed in basic editing.

I know it would be a nightmare in terms of enforcement, but I would like to have the ability to deal with sensor spots and dust effectively in a basic challenge.
Fixing dust & spots doesn't really feel like advanced editing to me. Not really in the same category as altering the look via filters & such.
Just my two cents..

As I stated earlier, the rules should be updated. If a challenge requires anonymity, a dust spot in a certain area of one's sensor is, in effect, that camera's fingerprint.
I make a motion that we update basic challenge immediately to allow for the removal of dust or specks!
--
If you can neat image it, why can you not remove a small piece of dust? If you can sharpen it, why not remove a piece of dust? If you can adjust the hue, white balance, compensate for vignetting, why can you not remove a speck of dust? If it's to conserve photographic integrity, I see no point. Like I said, anonymity is a big factor and it can be identifying.

Dangit, now I have to clean tea specks off my monitor. LOL

Here's an example / case in point:
I had serious sensor spot problems with this photo (I still don't know how it suddenly got so dirty, but it is clean now ). For pride's sake, if nothing else, I would have loved to have been able to clean up the spots. Had I been able to, I don't think it would've substantially changed the score, but I sure would've rested easier the night before the deadline..

Have you tried cropping!!! ;-) |

In this case, the dust is in an area where cropping would affect the dynamics of the image.
I've tried all sorts of techniques such as neat image, channel mixing, gaussian blur etc. Nothing helps and everything hurts the rest of the image.
Unfortunately, the image was taken 100 miles from here so reshooting with a cleaned sensor is not an option.
I guess I'll have to hope the voters understand the limits of the basic challenge and can overlook it.

You can use a dust reference file from the camera and and use Nikon Editor.

OK...What if someone made a program and put it up for download. Then, every photo in basic challenge, you can click the compare button and it will run it like a fingerprint against its database and tell you who the photo belongs to. I think I'm onto something here.

Unfortunately, using a dust reference file equates to using data from mutiple images, if I interpret the nature of the dust reference file accurately.
Additionally, even though done automatically, the actions of Nikon Editor to remove specific spots are still spot editing, same as if you were to select them based on some criteria and replace them with surrounding color.

kirbic: I think your understanding is correct and yeah, it's basically doing some spot editing automatically. I wish it was legal though :) |

Sometimes you can recognize a particular photographer by his style or a favorite shooting location, but going out of your way to defeat anonymity would probably earn you a long vacation from the site. |

What scalvert said, plus, I'd point out a few technical problems with this scenario:
- You'd need a valid, current reference from LOTS of users. Where would one get this?
- Dust patterns change, and in the period between entries, they can change a lot
- Even something as simple as cropping could make it very difficult to match even a good reference against a given target image... let alone rotating, flipping (legal in basic) or a combination of the above
- Dust may not appear at all for shots made at large aperture
- Referring to above, at what aperture would the reference be shot?
- Noise and detail can easily obscure dust
I could go on... but you get the idea.
