The objective is to remain faithful to the original experience, and to never deceive the viewer or misrepresent the reality of nature.
Adjustments that are allowed:
removal of sensor dust spots
removal of chromatic aberration
removing background noise (in moderation)
levels (in moderation)
curves (in moderation)
colour (in moderation)
saturation (in moderation)
contrast work (in moderation)
shadow and highlights (in moderation)
sharpening (including selective sharpening) in moderation
cropping in moderation and as long as a suitable high-res TIFF file can be supplied for printing a large exhibition display
dodging, burning and toning (in moderation)
neutral density gradients (in moderation)
removing lens vignetting
panoramas ie panoramas created from several images that have been taken from the same location and at the same time, and then combined or stitched using digital techniques, and resulting in a wider view than can be achieved with most wide-angle lenses.

(NB: stitched panoramas must be declared in caption information)
