Using the Transform Tool

I'm just going to show you one other part of camera. Thank me. Open more than one picture here. They're all those tabs and camera will. Let's look at the tab over here that is called actually in camera. It's not a tab, it's at the top here. There is this icon, which, if you were in light room, would be, ah, category in the right side of your screen. But when you click on that icon, then what's on the right side of your screen changes as if you went to a different tab and let's see what's here. Um, there's these settings, which are known as transformation settings and then related to them. There's another set of settings. If I go back to the hand tool that's up here and actually go to a tab, I personally think the feature should be a tab. There's also this, which is lens corrections and the too often need to be used together. So let's look at those two features first lens corrections. I noticed the top of this huge picture frame has a bend to it. If you look at the edge of the file, you...

might notice this parts lower. This part is lower. The middle is a little bit higher. Well, that's because the lens that I was using distorted the look of the picture. Well, there's a choice here. This is enable profile corrections. And that means the Dhobi has tested a bunch of lenses, including the one I shot with, which was a 12 to millimeter lens, and they took a picture of a grid. And if they noticed any distortion in that grid, they measured by how much and they saved. It is what's known as a profile, which described how much that lens bent the grid. When I turn on this check box, it will use the information in that profile to try to straighten that. Now my copy of that lens might be slightly different than the version Adobe had. So after you turn that on down here at the bottom, there are two sliders, distortion and vignette ing, and you could push this up to say, doom or compensation or down to do less. Just in case you're a copy of the lens was a little different than the one Adobe had also what it's doing. Is it measures If the corners of the grid that they photograph was darker than the center. And if it was, it measures by how much. And it compensates for that as well. If I don't want it, Teoh, I could bring down this slider called Vignette ing, and it wouldn't or my copy of the lenses more extreme in the one Adobe tested. I could bring it higher. So that's what got rid of the curvature that's here. And that's under a choice code lens corrections. But now let's go up to that icon at the top of my screen that looked like a little grid at an angle. With that one, I can now have sliders to correct for the fact that my camera was not perfectly level. Here is a slider called Vertical and watch what happens when I move it. If I move it one direction, it's gonna tell the image one direction, and if I move it the other, it will tilt it the opposite amount for opposite direction. I'm attempting to try to get the verticals that are here to be straight. I don't have to do it by manually moving these sliders, though there are icons above it, and this icon tries to make horizontal lines horizontal. This tries to make vertical lines straight, but that doesn't always do a great job. So there's an icon on the far, far right where you can do it yourself. You move your mouse onto the image. You get it to align with the edge of a vertical line. Drag. Get it to a line on Lee. After you've added two of these lines, will it actually change your picture? So I'm making lines that are parallel with the edge of the picture. Suddenly, it straightens. The top is tilted a little bit, so I can also click on the right edge, dragged the left edge and create a line that's parallel with the top of the picture. And if you want to, you can do the bottom. You could go up to four lines, and it's gonna make sure they're perfectly horizontal and vertical. That was in that tool that looked like a little grid two tools over to the left or the crop tool. And if I grab it, I could click and drag within my picture to say I don't want the whole image. I only want that portion. Then if I get out of the crop tool, go to the hand tool. There's my end result. Nice and straight. This can even do things like fisheye lenses. This was taken with a fish eye lens. If I start on the right side of my screen under that thing called lens correction, well, they will have measured how much the fish. I would bend my picture so I could just turn on one check box to fix that. Then I could come up to the icon in the upper left that we use, the one that looked like the great at an angle. And maybe just tell it to make verticals vertical or both that means and get it really close who are used the manual tool, but we can even correct for that kind of stuff.
