@ryanchg:
Yes i hope it's just the firmware that need some tweaking and fixing!
This pic look blurry/fuzzy on the edges on the flowers if you look closely(maybe one have to enlarge the pic to a more normal size to see. Perhaps that's a firmware issue.

This one is okay but has fuzzy edges on the flower.
(macro, auto mode)
blurry/fuzzy edges that you mentioned is because of
lossy JPEG compression.
first the picture will be transformed from spatial(height and width) to frequency space, via fourier transform. then a lowpass filter will be applied. that means high-frequency information will be cut off. high-frequency information is about high variant regions i.e
edges. then it will be transformed back to spatial with inverse fourier transform. now we have smaller image because some detail(that is not very important for human eye) are missing. this image will be compressed further with lossless LZ algorithm, though overall process is
lossy, that's why you see those fuzzy edges.
NOTE: i simplified the process, for details read
JPEG on Wikipedia.
sorry for my bad english.

for shoot better pictures i recommend:
1. don't touch
ISO, let it be
auto, the camera has better decision whether the ISO should be.
2. instead, play with
EV(exposure value), it will affect ISO, but these two aren't the same.
3. use
BestPic if possible.
4. if you end up with a washed out picture, try
PhotoDJ(auto)
so all settings should be
auto, only play with
EV.
and two important rules are:

LEARN YOUR CAMERA....
ps...the light on a object is rule number 1
pss....adjust the whitness balance with your D-Pad..(strong sunshine -0.3 or -0.7........low light +0.3 or +0.7 )..thats rule number 2
thanks plankgatan

Yup. I took o night shot this evening and runned it through photo DJ and i prefered the shot before photo dj. It made the shot a little darker, perhaps in order to reduce a little distortion. But in this specific shot i prefered to seee more detail and keep the (little) distortion. It's as i said very often a matter of personal preference. But it's nice to have many options! Are those shots taken in England?
PhotoDJ will perform Histogram equalization in auto mode. play with EV and PhotoDJ, and see when PhotoDJ performs better.

and about Stabilizer: see
Image stabilization on Wikipedia
note that K850 hasn't IS-equipped lens, so Stabilizer mode simply decreases resolution, then buffering and tracking movement to reduce
motion blur caused by a shaky hand, so resolution may decrease.

@sadeghi85
Thanks for the tips!
But what is equal to "EV" in the K850 menues? And i don't recall that there is a "fine picture quality mode" in the menues. I have, off course, chosen the "5MP" mode.

If you click on any thumbnail to view the photo you get "Additional Information" down on the right side with camera details.
