Photoshop - Selections and Masks

We examined a selection of channels and how these features of Photoshop to add so much creative potential. Mixing of these tools to masks to open a second in the world all its own. Masks, you can combine objects and move objects. Your friend may be permanent in the Himalayas, the product can sit on the presidential desk.

Masks do just that. The "mask" a portion of your image is simple enough, but with layers of Photoshop, it is very easy to make other things in your image. Of course, as you mix them in an intelligent way, you can create your own scenarios, and the ability to create much of the magic of the mask.

We would like to implement simple exercises that focus on the basics of how to use a new tool. Once you're familiar with how it works, you can move on to more complex applications and creative. To apply a mask, a playground is very similar to our models of selection. We'll select an image in a particular context, then the mask, 'Hide' in the background, then another layer appears. You can use two images, one as your foreground object, then copy each other in the first as a layer. This mask works by exposing the images from another hidden layers so that you can think of these two images, these two layers, as your two scenarios.

For example, you can have a picture with the candle on the table, but the second photo is an outdoor scene. When we apply the mask to the selected item is different in the background so you could have your pet on the patio, then apply the mask, which put him on top of a mountain.

Once you select the two images to work, make sure your have placed in the same image, in the same file, but in two different layers. If you are unsure about this, just copy your complete 'second' image, return to his first, create a second layer, selecting the icon of the extreme right in the bottom panel layers, along away, and then copy the second image in the new layer. You want to be in the context of the slide beneath the first layer and the first layer is the only visible. Only when a mask is applied to the second part of your image to show through.

Now create a selection of objects that appear in both images. I will use a candle to the rest of this exercise, I will turn my sail. I will make a selection of my sailing, but now I will add a layer mask of the selection, select the third icon from the left in the bottom of the Layers palette. This option is like an empty circle placed inside a square. Clicking on this option, a layer mask is created for you with its selection as part of the definition of the layer mask.

When you create a mask, you'll see the rest of the images will be lost. In my case, only the candle remains, but I see that I copied the image on the second layer. This is pretty close to instant gratification! You can apply the mask, and as soon as you are now in a different background!

With what we have learned about choices and channels, there must be a new channel at work here ... and there is. If you go to the tab of your system, you will see the creation of layer mask created a new channel. This understanding of how the information is kept and stored, is useful because you get more creative with your designs and return to the previous ones.

Knowing this newly created "mask" is actually a channel means that you can do all the things we've learned so far: You can load the channel as a selection of reuse, you can record the channel with a new name and can save the channel to a different file.
