movement for the purpose of a photograph is not allowed.
No modification that changes the truth of a Nature image is allowed. Images may be cropped but no
other technique that removes, adds or moves any part of the image is allowed.
Techniques that remove elements added by the camera, such as dust spots, digital noise and lens
flare are allowed.
Complete conversion of colour images to greyscale monochrome is allowed. Partial conversion,
toning and infrared captures or conversions are not allowed.
Images of the same subject that are combined in-camera or with software by focus stacking
or exposure blending are allowed. Multiple images with overlapping fields of view that are
