Here is another quick tool tip that will show you how to straighten the horizon in Photoshop CC. Let’s be honest, we have all taken a photograph were the horizon has been slightly tilted. If the image in question feature a lot of rolling or mountainous terrain, you may get away with a slight slope to the horizon but it becomes very noticeable when the horizon is a water line. So I’ve picked the image below to demonstrate how easy it is to straighten the horizon in Photoshop.
This shot was taken from the banks of Lake Garda in northern Italy and you can clearly see that the left hand edge of the water is higher than the right hand edge. It needs to be straightened.
Select the crop tool and a new tool bar will appear at the top of the work area.
