Masking an image by its very definition is concealing a certain parts of an image. Applying a mask to a specific region of an image actually makes it resistant to any changes done such as background change, cropping, exposure correction, etc. The masked portion of the image will remain stationary allowing it to be combined into another different image. Photo editing utilizes two types of masking for manipulating the image such as a clipping mask and a layer mask.
A photo clipping service relies on these two forms of image masking to selectively alter the different portions of an image. However, many photo editors use image masking for various creative purposes in a photograph. With masking, it is possible to alter an image entirely and create dreamy like images that are difficult to capture. The following are some of the creative uses of image masking in photo editing.
Compositing Two Images
Photo editors tend to rely heavily on image composites for altering an image altogether with various additions. A composite refers to two or more images merged together to obtain a final altered image. It involves adding the portions from a photo into a background image to create an entirely different scene. Masking using compositing opens a new vista in image editing, as it has made possible the creation of digital artworks that recreates situations and places, which are impossible to photograph originally.
Selectively Adjusting the Image
Masking is another way to selectively extract the image from its background and using it on a different image. Such selective adjustments are done for various creative and aesthetic purposes for an image. For instance, selectively adjusting the image can actually highlight a specific portion of an image. A classic example of that would be an image with a selective color to only one element whereas the rest appears in monochrome. This would highlight the colored object, which can convey a meaningful message while also giving the image more appeal.
Replacing the Skies
To get a clear blue sky is the desire of every photographer, as it would provide ample lighting and great backgrounds for the images. In photo editing, the process of masking can actually replace a dull sky with a more vivid and blue skyline. Adding a sky can dramatically enhance the appearance of the image and make it appealing at first glance. In masking, the sky is selectively processed so that the image gets a new makeover with the addition of a new clear sky background.
