Photos masking is a process of graphics software like Photoshop to hide some portions of an image and to reveal some portions. It is a non-destructive process of image editing. Most of the time it enables you to adjust and tweak the mask later if necessary. Very often, it is efficient and more creative way of the image manipulation services.
Photo Masking is usually either about changing the transparency level of the portion of the picture or removing it from the rest of the image. Masking comes very handy when you have to remove a portion of the picture from the rest but the poorly defined edges are making things difficult for you. The photo masking service of various photo editing tools is used widely for designing the product catalogues as well as presentations. The photo masking feature is often used in combination with the technique called clipping path. They are used to remove the background from a complicated or difficult image. Such images are mostly used commercially on the eCommerce websites. This feature becomes all the more useful when clipping path cannot be used on translucent pictures, fur, hair, smoke, flames, feathers and more.

Why Do We Need Masking?
It Is a Non-Destructive Technique
Masking is a non-destructive process. We can make changes later or fine tune to our masks whenever we need to. But if we erase the unwanted areas it is difficult for bringing those if we need those areas later on the process of image editing. Same is true if we cut an object or portion from the image making path on them. We will not be able to include more adjacent areas easily. Just if we want to hide some area we’ve cut out, it may be possible by using the masking technique. So it is very hard to avoid masking again, right?
Just to Hide and Show
As I mentioned before, the simplest use of masking is to hide and show portions of pictures. We can give transition effect if we use very soft brush or gradient for masking. Sometimes, we can control the transparencies of areas of a picture, like a very shiny sky. If we want we can make a very bright sky area dimmer (making the area semi-opaque) just by brushing the area with a gray color. Of course, there are other options to achieve this, but this is the easy and handy technique maybe you opt for.
To Modify an Area of a Picture
It is very common that you need to modify an area of the image. For example, you want to change the color of the top garment of a model. You can make a mask by making that portion visible. Then you can apply any kind of modifications you want; like color adjustment/correction, brightness/contrast adjustment, exposure correction, etc.
Making Collage Images
We can make interesting collage images using the masking technique. The possibilities of making collage images is really endless. We can make interesting effects using various photos and applying masking on them. Using soft brushes and gradients of grey, will make the transitions smooth.
