Another way to avoid hand shadows when taking a closeup picture from above is to use the telephoto lens. This will allow you to be more removed from the subject so your hand shadow will be less visible or invisible when falls outside the frame of your picture.
Can you explain how to use telephoto lens to avoid hand shadows when taking a closeup picture from above? I assume it is a feature in note 8 but I do not know how to use, what to press. Thanks
