In traditional photography, a photo negative is what you see on a roll of developed film; the darkest and lightest areas of the image are reversed, resulting in a positive print once taken into the darkroom. It is also possible to create this effect digitally with a single click in a variety of editors.
To create a digital photo negative, both Topaz Adjust and Topaz B&W Effects both have this function under Global Adjustments -> Curve Tool -> Negative. Additionally Topaz Adjust has this function under the Film Collection -> Color Negative.
You might be asking, “What’s the purpose of reverting an image back to a negative?”. Artistically this effect can produce some neat results, particularly if you’re into the abstract. Here are some examples of a digital photo negative:
