Level Photos - Step by Step
Step 1: Find a tilted photo and open it in Photoshop.
Step 2: Select the Ruler tool from behind the eyedropper tool by clicking and holding on the eyedropper icon then selecting the ruler from the menu.
Step 3: Find a line in your image that should be level (horizontal) but isn't due to the tilt of your picture.
Step 4: Click on one end of your line with the ruler tool and drag along the line that should be horizontal. Release your mouse button to set the ruler tools's line.
Step 5: Select the "Image" menu in Photoshop then the "Rotate Canvas" option then the "Arbitrary..." option.
Step 6: Simply click OK when you see this dialog box. The correct angle should automatically be entered in the "Angle" box.
Step 7: Photoshop will then rotate your image and add some white space around the edges to accommodate the entire image.
Step 8: Select the crop tool from your tool pallet and crop out the extra white around your image.
Step 9: Your picture should now be perfectly level. Just save and enjoy.
