Yeah, looks really good now 
Used Photoshop (allways do), wasnt really difficult, simply set the whitepoint and blackpoint manually under levels then the rest of the colors came to live. Basically the picture wasnt really poor, it was a wrong description of me to use in my first post about the picture, the picture has the sharpness and the colorinformation it needs, only problem was the camera had selected a wrong whitepoint giving the blueish tint. Correcting that whitepoint (and blackpoint to give the full range of levels) in Photoshop was all that was needed.
1. open the image in photoshop (or similar imageeditor)
2. under image adjustments, select the levels tool
3. in the levels tool, select the white point selector and click on the part of the image one thinks should be the whitest spot
4. in the levels tool, select the black point selector and click on the part of the image one thinks should be the black spot (the black text)
And voila, almost perfect picture.
Naturally this is only possible because the picture taken by the S700 is basically good, except for the misjudgement of the white point. Using manual settings and spot photometry when taking the picture, it propably would have been able to determine white point better.
Allthough the determination of white point can be a weekpoint when using autosettings on the S700, its still not enough to make it a poor cam, because its fixable. The problems you see in most other 1.3mp mobilecams are not fixable, and thus I still think the S700 are by far the best 1.3mp mobile cam on the market.

Thanks for the pointers.
There are some pics I have of my kids, which are good pics but can be turned from good to great with a bit of adjustment.

No, you're not right. The K750i is simply better than the S700i.

Yes, we know that, duh !
But i am right when i say that picture you took with the S700i is a poor one - not the cameras fault but the person taking the picture.
The S700i has proved its capable of taking pictures much better than that poor effort.

Not sure which pictures you mean or what you dont beleive, but personally I never use any sharpening tools on my digicam or mobilecam pictures. I find it most of the times just ruins the pictures. Make them look unnatural. If its not sharp enough in itself, then I simply dont use it.
The only tools I ever use to correct cam pictures, are those needed to fix a colortint of some sort, and very occasionally a very light noisefilter. But mostly I prefer not to touch them at all or only very litle, want to keep it as close to the original as possible.
The samples in this thread were untouched except for the resizing.
I do get as many "poor" shots as I get good shots with my cams, cause no cam is perfect (and neither is the photographer), but the "poor" shots I just throw away, and focus on the good ones. I also ususally take several shots of the same, and then just keep the best.

I agree... cams are not perfect. Hence why even famous photographers take multiple shots when taking pics in order to keep the best. There are so many factors that can throw off a picture sometimes. shakes, shades , angle, lighting, ect......
One's creativeness provides an optimum picture.
I myself am constantly trying different things and continually learning.
There's always something to learn in order to maximize the chances of a better pic.
I have a Sony Cybershot (about 3 years now ) S85 / 4.1 MP
Great for portraits.
When I go to my kids basketball games, I take my Canon AE 1 / 50mm as I am sure to get great action shots. With objects moving, I go to my Canon.

You're right man, i'm not a professional photographer but i have a very big interest in photography world and i know even a very professional ones take hundreds shots only to choose some of the best ones. lol.
And guess what? they even tweak the pictures in photoshop.
I'm an owner of evolt 300, contax 645 and canon a 520 that's why i don't use the cam feature of my K750. I was impressed with the phone only because the shape (look), resolution, size and the color (black one).
@ numb,
why did you tweak them first if you want to compare pictures side by side? compare with the original ones that came straight from the cam!.

Nice comparison pics.
In my opinion the S700i pics look livelier colourwise although there is not much difference between them.
What puzzles me slightly is that I expected to see a more pronounced differrence considering one of the phones has AF. Did you use the AF feature?
On the pictures I took with my S700i the vertical lines near the edge of the pic seemed to be more convex. I expected this to be eliminated or at least reduced with the AF feature.
I would like to see a comparison K750i pic taken with and without the AF used. Lets see the AF in action!

You allways see the AF in use as you cannot turn if off in K750

I was under the impression that you had to first press the button down half way and hold for a few seconds to let the lens focus and then press further to take the pic - just like on a normal digital camera!
Is that not how it operates?

@goldenface - If it's anything like my CyberShot digital camera (as it seems the K750i is based on functionally), the autofocus will work regardless of if you half-press the button or just fully depress the button. Even if you do the latter the camera will focus itself before taking the shot.

yes, it will allways autofocus even if you just press down quickly without pressing down halfway first.
Pressing halfway down first gives you acknowledgement that it is actually able to find a focus point (audibly and visibly), and that the focus point is what you intend it to be.
The object you are photographing may be such that no focus point can be found, and then it will just be out of focus, if you then dont do the halfway press first you wont know its out of focus.
It works like any other autofocus on any camera, only difference is you cannot turn it off and select manual focus.
