The Bezier curve is a tool originally developed for the design of car bodies, but over time it migrated to various graphic editors. In particular, in Adobe Photoshop CS5, where the Pen tool became its descendant. At first glance, it seems very complicated, but you just need to understand a little to appreciate it.
Necessary
Russified version of Adobe Photoshop CS5
Instructions
Step 1
Run the program and create a new document by clicking the "File" menu item, then "New" (or the keyboard shortcut Ctrl + N), specifying in the "Width" and "Height" fields, for example, 500 each (other parameters can be left unchanged), and again clicking "Create".
Step 2
Select the Pen tool (hotkey P) and left-clicking on the work area place two points at a small distance from each other, but sufficient to make a noticeable segment. When placing the second point, do not release the mouse and pull it somewhere to the side. The straight line will turn into a curve, and its curvature will depend on how you position the guide - the line that appeared after you pulled the mouse to create the second point.
Step 3
Right-click on "Pen" in the toolbar and select "Angle" from the drop-down menu (used if you did not create a guide after creating the anchor point). Hold the left button on the very first point and drag the mouse to the side. The same guideline will appear near the point. By changing its coordinates, you can manipulate the parameters of the part of the curve that starts from the first point. Thus, the resulting curve can be conditionally divided into two parts: one originates at the first point, the other at the second.
Step 4
You can continue creating the curve by placing a few more points and changing them in the same way as described in the previous steps of the instruction. To create an anchor point inside the line, use the Pen + tool, and delete - Pen-. Each line you draw in this way will be displayed in the "Outlines" tab of the "Layers" window (if it is not there, press F7).
Step 5
If you want to save the result, press the key combination Ctrl + Shift + S, in the window that appears, specify the path, write a name, specify Jpeg (if you want to get a picture) or Psd (if you want to save the entire project) in the field "Files of type" and click "Save".
