PSA definition of Monochrome Photography:

An image is considered to be Monochrome only if it gives the impression of having no color (i.e. contains only shades of gray which can include pure black and pure white) OR it gives the impression of being a grayscale image that has been toned in one color across the entire image. (For example by Sepia, red, gold, etc.) A grayscale or multi-colored image modified or giving the impression of having been modified by partial toning, multi toning or by the inclusion of spot coloring does not meet the definition of monochrome and shall be classified as a Color Work.

FIAP Definition of the black and white photography (monochrome):

A black and white work fitting from the very dark grey (black) to the very clear grey (white) is a monochrome work with the various shades of grey. A black and white work toned entirely in a single colour will remain a monochrome work able to stand in the black and white category; such a work can be reproduced in black and white in the catalogue of a salon under FIAP Patronage. On the other hand a black and white work modified by a partial toning or by the addition of one colour becomes a colour work (polychrome) to stand in the colour category; such a work requires colour reproduction in the catalogue of a salon under FIAP Patronage.

PSA definition of Photo Travel Photography:

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.
