Here is a post of mine on a method of achieving a result similar to cambering a blade:

Beforehand a 2" wide blade on a #5 was used to take a full 2" shaving.
If my desire was to take a narrower shaving, it would make sense to me to use a plane with a narrower blade.
The 'camber effect' as shown in the link above can be done with a few swipes to either side of the blade on a fine stone. The stone used in the post is a translucent Arkansas stone.
My bench is also used to check my work. If a bunch of pieces are on edge on the bench it is very easy to see which, if any, are not square.
