Default Xperia Z1 Camera manual settings

hi guys! Just wanna ask... Just tried fiddling with the camera today and noticed that the built in camera app of sony doesn't have settings for contrast, saturation, exposure, sharpness etc. Or did I just miss it? If so could you guys tell me where to look for these settings? I can't find it in manual mode. Cause all I can see right now is a setting for white balance and EV. Now how about if I want to create artistic pictures with high saturation and lowered exposure? I hope it's not album post processing only cause there's a difference when you can see the result first hand in viewfinder than the already taken picture.
