Is it hard to determine whether the photo taken is straight and level?
If you have this problem, this gadget is designed for you.
This dual axis bubble level is designed to indicate whether a surface is level or plumb.
When attached to the camera hot shoe, you can easily determine its level.
The dual axis facilitates you when taking photos in both portrait and landscape orientation.
It is particularly useful when you mount your camera on a tripod.
This is very nice for doing panoramic series too.
It helps make sure that your photos will actually stitch together when all is done.
