In Photoshop, masking is a way to separate objects from the background. The term "mask" refers to a grayscale image that determines which pixels will be visible and which will be hidden or transparent. Masks are useful for compositing images as well as changing the opacity of an object (by adjusting levels) in an image. It can also be used for keying (using luminance values of one image to selectively control what's visible in another).

Masking is incredibly useful when making photo manipulations because it allows you to erase specific parts of an image without harming other areas, like hair or fur. Masking is also essential for creating composite images where two photos are seamlessly blended.

What is Photo Masking?

In general, Photo masking has many uses. It is a quick and easy way to remove or extract objects from an image. In addition, photo masking can also be used to clean up images with power lines and other unwanted objects in the background. Removing these objects can help make your image more appealing and give it a custom feel.

Photo masking works by selecting parts of your image you would like to keep visible while making other parts transparent or invisible. Masking allows for greater customization which ultimately gives you greater control over what appears in your finished product. You can also choose the photoshop masking service to mask the images very well.

How do I start using masks?

Using masks is simple! First open both images that will be combined into Photoshop's Timeline panel or via the File > Open dialog.

Next, select an image and click on the "Add Layer Mask" button at the bottom of the Layers panel to add a mask. Make sure this is your background photo. If you want to use a different image as your background instead, just drag it onto the New Layer button at the bottom of your layers palette.

With this photo added, we can now begin removing unwanted objects from our scene - like our subject's hair! Once we've finished masking out everything we don't want in our photos, we save and close out of the file and return to Photoshop Elements.

We then open up our subject image and add a new layer with an empty mask (we're going to use this picture as our subject). We then click on the New Layer Mask button and choose "Reveal All". Doing this will make our original mask (the one we used to cut out the subject) appear, giving us a nice clean base for our subject image.

When we like how it looks, we save and close out of our file and return to Photoshop Elements. Finally, we open both files in Photoshop Elements and combine them together using the "Move Tool." Now your masked images can be combined into an interesting and eye-catching final product!

What is the advantage of masking in Photoshop?

The advantage of masking in Photoshop, is that it allows you to do things with an image that would be impossible with a regular selection. It allows you to fade or transition areas of your picture while keeping the area's colors and tones intact. You can also change the color within some objects without affecting the rest of the object.

For example, if you wanted to remove red-eye from someone's eyes in a photo, you could use a layer mask and paint over the eyes with black (or any dark color). However, even if black isn't used for this purpose alone, artists sometimes find painting on their masks more useful than working with selections; With Layer Masking they can add contrasts and details on top of what has already been selected, whereas with selections the only option is to use feathering or anti-aliasing.

Another advantage of masking in Photoshop, is that it can be used to colorize line art. If you have scanned a black and white image and want to paint on top of it using layers, any areas of your picture which you paint over will turn out solid black unless they are on top of another layer. However, if you use Layer Masking then any area of your photograph that doesn't intersect with other layers won't be affected by the painting part of the layer at all; It will act as though it wasn't painted on-top.

Summary

Masking allows you complete control over what is displayed within an object via Layer Masking, and it can be used to easily reproduce the same composition over and over again by duplicating the Layer onto which you have masked.
