Masks help to select specific picture areas and edit our or fade down others, in other words to edit single sections of an image separately from eacht other. Masking paths define an object for further editing and are used for creating different coloured versions, clipping or montage.

Masking paths are a helpful tool in digital image processing as they make it possible to edit an image without permanently altering the original image. Therefore, they are gladly used in the creative process to try out different possiblities.

Photomontages are based on the technique of collage. Several images are put together to create a new one. For instance, one can give a new message to an image by integrating another motif or object.
