Some pictures are the result of haste or inexperience of the photographer - the image in them is tilted left or right, or even turned upside down. You can correct this oversight using Adobe Photoshop.
Necessary
Adobe Photoshop
Instructions
Step 1
Launch Adobe Photoshop and open the desired photo in it. To do this, click the menu item "File"> "Open", in a new window select the required file and click "Open".
Step 2
Click the main menu item "Image"> "Image rotation". The list that appears will contain several items. If you need to flip the photo upside down, click “180 °”, if you want to tilt the photo to the left, click “90 ° CCW” (90 ° CCW), if to the right, click “90 ° clockwise” (90 ° CW). Also notice the Flip canvas horizontal and Flip canvas vertical items. With their help, you can create a mirror image of the photo in one click, horizontally and vertically, respectively.
Step 3
There remains one more item - "Arbitrary". Thanks to him, you can tilt the photo at a certain degree. Click on it and enter the required value in the "Angle" input field. The side of the slope is set using the points “° clockwise” (° CW) and “° counterclockwise” (° CCW). Click OK. As you can see, the photo has been tilted at a given angle, and at the same time the canvas has been increased to show the edges of the image.
Step 4
In order to save the result, click the menu item "File"> "Save as" or use the faster way - hot keys Ctrl + Shift + S. In the new window, enter the name of the future file, specify the Jpeg format and, if you save the result to the folder with the original file and do not want to lose it, check the box next to the item “As a copy”. Finally, click "Save".
Step 5
Using the History panel (to open it, click Window> History), you can go back to any action you did earlier. Use it if you made some mistake.
