Do whatever you want but don't be insulted if the "common public" or the jurors at an exibition think your work has no merit.  There is a common area in which certain conventions are accepted and others are seen as strange.   

Les Paul was ridiculed when he tried convincing the guitar makers to try an "electric" guitar..that broke the convention of the time. The Beatles released the first memorable "theme based" album and the single 45 disc hit the dust...sometimes when conventions are broken the result is wonderful, sometimes not.

Each camera with auto exposure has the basic "technical conventions" built in.  What you do with that is up to you. Still, any piece of art or new thought or twist of an old thought or method is either accepted or rejected much according to the ingrained conventions of the viewer, whether cultural or from the ivory tower cirtics strict standards.

As with the electric guitar..the intention was the same: Music.  With bending convention you do risk rejection but many successes are build on just such a bend or twist.

I want a pic of a nephew "making a face" and my mother-in-law wants the kid posed straight as a board...go figure.  Go do you own thing but remember some convention does create more appeal to others.             just a thought or two.        TomDart.
