You must:
* create your entry from a single capture.
* retain your original, unedited file (exactly as recorded by your camera)

You may:

* use any feature of your camera while photographing your entry, with the exception of combining multiple captures in-camera.
* crop, rotate and resize your entry.
* use filters or stand-alone utilities designed to preserve image integrity (such as Neat Image, Unsharp Mask, Dust & Scratches, and color correction tools). These filters must be applied uniformly to the entire image, and must not be used in such a way that their use becomes a feature. No “effects” filters may be applied to your image, with the exception of Noise and Gaussian Blur.
* saturate, desaturate or change the colors of your entry, but no selections are allowed.
* use only Adjustment Layers (or their equivalent). An Adjustment Layer is a special type of layer containing no image data that lets you experiment with color and tonal adjustments without permanently modifying the pixels. Adjustment Layers must be applied in Normal mode.
* add a border to the outside edge of your entry. Your border must be distinct and clearly recognizable as a border.
* use RAW conversion software as long as the changes are made globally to a single file on one layer and do not create new features or effects in the process.

You may not:

* spot-edit your entry, except to remove sensor dust or hot pixels.
* use the same original image in more than one challenge.
* use any selection tool, including but not limited to the marquee, lasso, layer masks, quick masks, or any similar tool to select a portion of your image for any reason other than cropping or creating a border.
* use ANY editing tool to create new image area, objects or features (such as vignettes, lens flare or motion) that didn’t already exist in your original capture.
* add text to your entry or its border during editing. This includes copyright statements.
* distort or stretch your image in any way.
