A Photo Travel image expresses the characteristic features or culture of a land as they are found naturally. There are no geographic limitations. Images from events or activities arranged specifically for photography, or of subjects directed or hired for photography are not appropriate. Close up pictures of people or objects must include features that provide information about the environment. Techniques that add, relocate, replace or remove any element of the original image, except by cropping, are not permitted. The only allowable adjustments are removal of dust or digital noise, restoration of the appearance of the original scene, and complete conversion to greyscale monochrome. Other derivations, including infrared, are not permitted. All allowed adjustments must appear natural.
