Do your pictures ever look a bit off-balance? One possible cause can be a crooked tripod. Fortunately more and more cameras are adding a tool for leveling the camera called a virtual horizon. It functions similarly to an electronic level.
In this image, the camera looked straight. But checking the virtual horizon, I could tell the camera was slightly titled. Turning this option on varies by camera, but it usually involves using a pre-assigned button or accessing a menu item.
Adjusting the height of a tripod leg I leveled the camera to get a better shot. By slowly raising one leg, I can get the camera perfectly level. This method is best for panning shots or panoramas. You may also be able to adjust your ball head for a quick fix.
The virtual horizon graphic shows a green line when the camera’s position is aligned with the horizon. This tool is invaluable for shooting landscapes and architecture as it ensures straight lines and minimizes perspective issues.
Note: This is just one way to level a camera.
