My apologies, i was assuming you was talking about a video and not specific images...
Have you enabled the Rightlight technology in the Logitech software? Also you need to set
white balance to auto, downside with the white balance, each time you reboot the computer
you and to set the white balance back to auto..
So, to sum up, in the logitech software make sure Rightlight is enabled and white balance is set to auto,
You also may want to adjust the colour (or color depending on where you live but as your not far from me
then its colour lol) intensity
As a side note, Make sure Auto focus is set to manual and same with Follow Me, turn it off.....
I use the exact same camera and it looks like Lars is using the same settings as me

Lars, I notice you have the Antiflicker enabled, I dont think this is needed for external shots (outside view)
cause from what i gather its basically for the type of lighting in side the house, i.e. if your using Fluorescent
lights and using the webcam to show ya face on the net then you would use the anti flicker, if your using
normal light bulbs then its not needed, if your using candles then turn ya webcam off

if your pointing it
outside then then its not needed, just a heads up for you, heres a little explaination, i did a quick search lol
Flicker is caused by florescent lights. These lights do not put out a constant level of illumination, but rather vary with the amount of current flowing through them. 50Hz AC changes direction 100 times per second (first current flows in one direction, then the other for one cycle or Hz). 60Hz does so at 120 times per second. The intensity of the light is relative to teh level of current flow, not the direction, so on European power, they flicker at 100 times per second adn in the US they flicker at 120/sec. Setting the exposure time to match the flicker rate lets the camera gather light over the duration of one flicker period. This in effect averages the varying light level over one flicker period into one image, and since the exposure rate is sync'd with the flicker rate, each frame has the same apparent light level. When outdoors however, light levels are very much brighter, so 1/100 or 1/120 of a second lets a huge amount of light into the aperture, making the picture appear to be too bright. much lower exposure times outside are sufficient to gather plenty of light to produce a normal image. Exposure times lower than 100/120 would not be effective in reducing flicker, because each exposure time would be only a partial flicker, and there is no guarantee that successive frames would be in the same part of the flicker. This is why anti-flicker locks the exposure time to a minimum of 100/120
