Editing Nature Images
One of the most controversial aspects of Nature photography is the extent to which images (particularly digital images) can be altered after capture. Alterations to images can be grouped into two basic categories:
(a) adjustments that optimise image quality without altering the pictorial content of the image, (b) modifications that alter the content of the original scene, other than by cropping.
Broadly speaking, adjustments of type (a) are permitted and modifications of type (b), other than cropping, are not.
Put simply: Any form of manipulation that alters the truth of the photographic statement is
not allowed if the image is to be entered in a Nature competition.
