Unhappy [Q] can someone help me stop heavy post processing?

I have a sony xperia Z C6603 and I absolutely hate something about the phone. Before i take pictures it looks great (amazing even) as i take the photo the picture is perfect, then after a second it processes it so much i look more like an alien from outer space than a human being. Not only this but the files are also ridiculously small compare to all other phones. I've downloaded the FV-5 app and it's great, but my photos from my front camera stll lokks like horse s***. i do not want other setting configurations, because nothing fixes it... Has anybody made a fix for this via rooting or whatever? i've searched all over the internet after a solution , but can't seem to find one. One of you geniuses must have a solution, right? (have the 4.3 android version and 10.4.B.0.569 build number).
