Hey there!
Backlighting in photography is when the primary light source is located behind the subject. Most of the time, photos that rely on backlighting to not reveal any details of the front of the subject and only show a silhouette instead. So, this is false, since you will not be able to see any detail of the front of the object you are photographing.
Hope this helped you out! :-)
