Video: Understanding pixels

In order to really master Photoshop, you gotta know what's going on behind the scenes. We're going to talk about an important aspect of that, probably the most important aspect of that, in this movie. So I'm going to go to the Window menu and choose the Navigator panel. Now what we're going to do, is we're going to Zoom in on one of these edges that looks really smooth and round. I'm going to choose the top of the subject's head here. And so I'm going to go in the Navigator panel and Zoom in, and I'll have to rearrange this here. So I'm going to drag this window up, so that I can keep seeing the top of her head. Zooming in and reframing.

Understanding pixels

In order to really master Photoshop, you gotta know what's going on behind the scenes. We're going to talk about an important aspect of that, probably the most important aspect of that, in this movie. So I'm going to go to the Window menu and choose the Navigator panel. Now what we're going to do, is we're going to Zoom in on one of these edges that looks really smooth and round. I'm going to choose the top of the subject's head here. And so I'm going to go in the Navigator panel and Zoom in, and I'll have to rearrange this here. So I'm going to drag this window up, so that I can keep seeing the top of her head. Zooming in and reframing.

So, now that we're here, we're at about 367% Zoomed in, we're starting to see that what once look like a really smooth line is not really. I'm going to keep Zooming in and Zooming in, Zooming in and rearranging this here. And when I Zoom in all the way, 3200%, we can see very clearly that what's happening here, is that this image is actually made up of little tiny squares. Even what seemed round is made up of these little tiny squares.

These little squares, are called pixels, pixel, and pix, pixel is short for picture element. So that is what, are the literal building blocks of the images that we are working with in Photoshop. Now you'll notice that once we've Zoomed in to a certain resolution, we get this little white grid here. If I keep zooming out, It will eventually disappear. But this is called a Pixel Grid. And this is really helpful so that you can see that there's only one color per little square.

And I can go to the View menu and I can choose to go to Show, and I can deselect Pixel Grid if I don't want that to show, if that gets distracting. But typically I like to leave that on, so I'm aware of these little tiny squares. And often times when we have problems with our image, it is because of these little squares. And getting them to do the right thing, often times, is the great challenge of Photoshop. So again, regardless of what you're painting, whether it's a circle or square or a curved line, you're most of the time making these little pixels.
