There are six basic techniques of faking a photo:
1: Inserting details. This includes placing an element from one photo into another to create a composite image, reproducing a detail of the photo by cloning it, superimposing an image onto another, or drawing-in details.
2: Deleting details. This is usually done by extending background elements over the unwanted detail. Or one can crop out the unwanted detail.
3: Manipulating elements within the photo. For instance, adjusting the color, resizing details, or rotating or moving details.
4: Falsifying the caption.
5: Staging the scene. This is considered fakery particularly in photojournalism. Varieties of staging a scene include using models and cutouts and inserting a prop into the scene.
6: Taking a photo at a trick angle. The most common example of this is the use of forced perspective.
