1. A method of correcting airborne particle artifacts from digital images, comprising:

  • detecting a specific location within a digital image of an airborne particle artifact (orb), including;

    electronically identifying a defined curved plane shape within the image; and

    analyzing luminances of pixels within the identified shape to assess whether said shape in fact corresponds to an orb; and

    correcting the digital image by removing the orb, including;

    adjusting one or more pixel luminances inside the orb;

    adjusting one or more edge pixel luminances of the orb; and

    sub-sampling an original image to generate a sub-sampled image, wherein the sub-sampling comprises reducing angular resolution.
