You can use a tool called a loop to really zoom in on the quality of your images and really see the focus. And a loop is one of those little upside down shot glass kind of thing that they use in the real world and they flipped it upside down and put it on top of a newspaper for example where they can look at the pictures really clearly. Another comparison would be something that jeweler uses when he's making diamonds. So you know their really zooming in close on that zubic zirconia. So what I am going to do now is I'm going to expand my preview area here and I want to show you that we can, let me, let me go ahead as well and collapse the left side. We can also compare images in the uh preview window or preview pane or panel. So I can hold down my control or command key to add images to the preview. And as you see here I can look at them and I can look at the quality, I can compare the two of them or the four of them or how, however many I have in this list and likewise by holding down command or control and clicking again I can selectively remove images from this preview. So let's say I want to compare this image with this image. So I'm holding down once again command or control and I'm clicking to add that. Now let's say that I want to add more of them but I don't want to skip any of them. I have to hold down the shift key this time so I'll click on this one, I'll hold down shift and I'll come on down to this one and I've added all six of those in a row into the preview panel. Now there is something else that I want to show you that's really cool, I'm going to just select one image for now and I'm gonna move my mouse over and you see a magnifying glass. This is gonna help us to enable the loop feature when we click with our mouse, keep your eye on this little uh black uh area of the loop, we can see what it's focused on. So the loop is pointing here and we are seeing that right here. Now I can move the loop around and the loop will show me what's going on. So this is how the government does it. Uh ha they use a loop on us to spy, excellent. What I can also do to get rid of the loop is I can click when I see the hand again and the loop will go away. Another cool, thing I can do with this loop is I can click on it again, move it around to the corners and the loop will kind of spin around on its own. So the loop is really smart and it tries to find its way around in your images and once in awhile it will get a little lost so you have a little patience and wait for it to flip back around again. So once again its easy to use the bridge not only to compare images but to zoom in and out with the loop. And one more quick trip uh tip rather, I like to tell you about the loop is that if you like to zoom out while in the loop, hold down and press the minus key and press the plus key to zoom in and out of the loop of view magnification. Now once again to get rid of the loop simply click on the black arrow when you see the hand and it goes away and you're back at the magnification tool.
