Photoshop Tutorial 06: Photoshop 6 turns things around – Tutorial for Beginners

Photoshop tutorial 06: Photoshop6 reverses the world and reverses the world? It’s not that exaggerated, right? Wrong! Photoshop really works! Let Brother Corn tell you. It is rare that the image meets the requirements from the beginning. When copying an object from one picture to another, you often need to enlarge or reduce it. You may also need to make the inclined line horizontal, or flip it up and down, left and right. In Photoshop, these operations can be completed with just a few clicks of the mouse or the execution of a few simple commands. Isn’t it easy? Let’s get started. Resize
Photoshop makes it easy to change the size of an image or any object in it. There are two options here: resize the image or resize the canvas. The former is the enlargement or reduction of the image itself. The latter enlarges or reduces the working area and still allows the image to float within it. Generally, use the latter only if you need more working space around the object but don’t want to shrink the double-click image.
Resize the image
To resize the image, select command opens the dialog box shown in Figure 6-1.

 ( 1) Pixel Size – Here, it shows the size of the single front image, the size of the image can be changed by resetting the width and height of the image. If the Constrain Proportions option is selected, a chain on the right will appear, indicating that the image’s width and height will always maintain their original proportions.
 (2) Document size – Here, you can view the size of the image to apply for printing, and you can also change the printing size by adjusting the width, height and resolution. The units you can choose are percentage, inches, centimeters, picas, columns, and points. If you keep the image resolution unchanged and change the width or height setting of one option group in Pixel Size and Document Size, the width and height of the other option group will also change.
 (3) Resize image pixels – When changing the image size, Photoshop will redistribute the pixel colors of the original image to the new pixels according to a certain interpolation method. The optional methods are shown in Figure 6-4. Twice cubed is the most accurate allocation method.

Note :, Changing the size of an image may sometimes cause the quality of the image to be affected.
Reset the canvas size
The canvas size command allows the user to modify the working space around the current image, that is, the size of the canvas. You can also crop the image by reducing the canvas size. When the canvas size is enlarged, the newly added space will be filled with the current background color. Therefore, before changing the size of the canvas, make sure the background color in the toolbox is the required color. White is a commonly used color
Click, command will pop up the dialog box shown in Figure 6-7.

With The image size dialog box is the same as described earlier. You can choose your favorite measurement system from the pop-up dialog box. Enter the canvas size to be changed. Photoshop will display the size of the new file.
In addition, the difference between the canvas size and the image size is that you can use the anchor point to decide where to place the image on the canvas. As shown in Figure 6-8, after clicking the upper right corner, the size of the image in the picture has not changed, but because the canvas size has increased, the original image has also moved to the upper right corner. As shown in Figure 6-9.

Change the size of the selection area
You can also change the size of the selection area. To do this, use the most convenient tool and first select the object or the image you want to change the size of. When the marquee is active, select, command is shown in Figure 6-13. Place a window similar to a crop box around the object, and drag one of the control handles anywhere around the box to change the size of the selected object. If you hold down the Shift key while dragging the slot, you can also maintain the object’s aspect ratio. If there are handles on the side of the Guodong box, the height or width of the selected area can be stretched or reduced accordingly.

Rotation
When processing many images, they need to be rotated in order to operate more efficiently and conveniently. Photoshop provides powerful and precise selection tools. Execute, command, its menu is shown in Figure 6-16.

If To rotate the canvas at right angles without the angle, you can choose, command to open the dialog box shown in Figure 6-20.


Figure 6-20

In Enter the angle value to be rotated in the dialog box. If the specific value cannot be determined, you can set a value first. Then keep undoing or resetting. Selectand to determine the direction of rotation, click Complete. Flip an image is just as easy as in real life.
Mirror flip
Flipping is actually similar to looking in a mirror. The flipped image is the image after looking in the mirror. It can be flipped horizontally, as shown in Figure 6-24. It can also be flipped vertically, as shown in Figure 6-25.

Mirror Flip is different from rotation in that it changes the up and down or left and right direction of the image. Of course, sometimes we want to rotate the image as well as rotate it to get the image we need.
 Transform the selected object
The previous method can be applied to the entire canvas or to the selected object. What will be introduced below can only be applied to the selected object and not to the entire image.
Click, command, the drop-down menu is shown in Figure 6-28.

Rotation Similar to zoom and canvas commands, I won’t introduce them in detail here. The following mainly introduces bevel, distortion and perspective.
 (1) Beveling is not only to tilt it at a certain angle, it can also distort, stretch, and deform the image. Just like a piece of plasticine, it can be transformed at will. It distorts the selected object in all possible directions by simply dragging the control handle and dragging the selection area. Just press enter when you’re done. Figure 6-29 shows the rendering after bevel cutting.


Figure 6-29

 ( 2) Distort the selected area. All transform tools are similar, with some subtle differences in how they transform the selected area. For example, scaling and beveling can change the selected area, but the warp command does not change the size of the image, but squeezes and stretches the shape. As shown in Figure 6-30.


Figure 6-30

 ( 3) Change the perspective effect of the selected object. The perspective command is one of the most commonly used commands in Photoshop’s tool arsenal. To create an image that looks large near and small, the perspective tool is perfect. Its movement is very intuitive. When you drag a control handle at a top corner, its opposite corner will mirror the movement – when you click a control handle and drag the mouse outward from the selection area, the opposite corner’s mirroring handle will also move towards the principle selection area. Mirror movement. Conversely, if you drag the anchor point into the selection area, the mirror handles on the opposite corners will also move inwards. As shown in Figure 6-31.


Figure 6-31

Perspective The difference from deformation is that deformation can only deform one vertex corner of the selected area. When dragging a vertex in perspective, the two vertices will be automatically adjusted and mirrored at the same time.
