In this video we're going to take a look at the image functions in the title bar. So let's go up to Windows > Default Layout, and let's take look at Image. So, the first option is Image Size. Now, you'll notice that the image size comes up as 1360 by 725. Now my sentik is set at 1360 by 768, so we are losing a little bit of height due to the title bar. And we can change this option. So let's go to Edit > Preferences. And under Canvas, you'll notice there's an option that says Default Canvas size takes effect with file new.
And we have a check mark next to Use width and height of window. If I uncheck this, I can dial in explicit coordinates for the size of my canvas on file new. Right now we've got 1980 by 1024, I'm going to go with this. So now if I say File > New, and let's go back up to Image > Image Size, you'll notice that it's 1980 by 1024. And also under Image > Canvas, we have 1980 by 1024, which reflects our new dimensions.
I'm going to go back up to Edit > Preferences > Canvas. And I'm going to check that box back on. Let's do File > New. File > Add Image. Double tap. Let's scale that down, and Accept. Next option is Crop. So with Crop I can select a region of my image, and you'll notice that it invokes the Crop function in the toolbar. So we can dial in explicit coordinates like this, or I can check this link mark and it keeps the aspect ratio, like so.
Once I've done that, I can actually go ahead and move my selection box like this. I can accept, or I can reject. Once I've got that, if I accept, let's undo that. So, back up to Image. The next option we'll look at is Adjust. So, let's take a look at Brightness and Contrast. Now, these are all very standard functions that you would get in any digital sketching tool like Photoshop or SketchBook. And I like to have the Show All and the Preview functions checked on. So again, real time update on the values that I'm changing.
Next one is Hue and Saturation. Again, we can change these values. And we can undo that. Same with Color Balance. We can adjust the Color Balance. Let's undo that as well. We can change everything to a grey scale. And finally, we can Invert. Now, Invert gives us quite a strange result. Now, to explain this, I'm going to open up my Color Editor. Now, if you remember the body was red. Now, the inverse of red according to this color wheel is this cyan color. The inverse of black, which was the shadow underneath the vehicle, is white. So all the colors that we had in the original image have basically been inverted according to the color wheel.
Let's go back up to Image. We can rotate the canvas counter-clockwise. We can also mirror the canvas, like so. We can flip the canvas vertically. And we can also mirror a layer. Now right now, I'm going to open up my layer editor, and you'll notice that we only have one layer that contains all this data. In other words, the original sketch book profile can flatten into one layer. So let's just go ahead and add a layer on top like this. And I'm going to choose a white. Let's go here and just put in a graphic like that.
Back up to Image > Mirror Layer, and you'll notice it's only applying it to the active layer. And that's the active layer which has the blue background. Let's go back to Image. We can also flip the layer vertically. We can activate symmetry in x, and also, symmetry in y. And you'll notice, as soon as I activate symmetry, it invokes the Symmetry command in the toolbar, as shown here. And we have the blue lines, and a vertical and horizontal symmetry. We're going to take a look at symmetry in a lot more detail later on in this course.
A quick way to come out of symmetry is to use this top right hand corner x option that will completely eliminate all symmetry from this particular project.
