Can photographs be fixed in a Sony NEX-C3K digital camera?

I bought a digital camera by Sony A NEX-C3K which I read positive reviews about. I can't seem to find any photo editing adjustments that can be made in the camera like adjusting the contrast etc. I like to make certain adjustments before I put them on my computer but I can't find and settings in the camera to make adjustments with when the picture is in the review mode. I liked this camera because it was really small and because I have a couple of big cameras but they are too heavy to carry around all the time. But if this camera does not have the ability to adjust pictures and if it is the contrast then I will probably return it for a similar size camera where I have more to work with in the camera. I was thinking of the small Nikon which is similar to this or one of the Olympus Pen cameras. I really like the sony alot so I'm hoping maybe I missed something when I was checking out the camera…

The only thing that you have missed is that the competing cameras don't have this functionality either. It's something you may find on very cheap cameras, but tend not to appear on cameras in this segment of the market. Doing this type of adjustment on the cameras small screen is a very blunt tool, instead you'd be much better off downloading your images to the computer and then using Sony's PMB that was supplied with the camera to perform such adjustments.
