I noticed purple sky with 3000Z. I really like this camera and the features, but it seems as though I have to correct each picture with softyware. My friends Olympus 2000Z look great right out of the camera.
The purple sky being the most severe. In fact in some photos I had purple circles in the sky. When I correct with software the pictures do look very gook.
Is this common or am I doing something wrong ? All shots taken in normal and landscape modes.

Re: Purple Tint Sky
Auto white balance should work OK. I was thinking maybe you had accidentally switched it to the Fixed setting. Hmm. You said you were using Normal and Landscape modes. Just to see how it works, I would suggest switching from Program mode to Full Auto. See if that fixes your purple skies. I don't know why it would, but it is something to try

That is known as 'purple fringing' and is usually the result of the sensors and/or the lenses in your camera not being able to handle higher contrasts or over-exposure. Scientifically it has more to do with the how the camera sensor responds to the available light spectrum. (see: https://en.wikipedia.org/wiki/Purple_fringing) Have you notice it is generally more pronounced where a very bright (white) area meets a high contrast (black) edge (like a bright sky behind a dark or shadowed object)? Best way to avoid is to be careful about the relative light levels exposures when framing the shot---or using a UV filter. There are many photo editing programs which can help eliminate purple fringing in post production. Have a read through: http://www.photoforbeginners.com/news/tutorials/how-to-remove-purple-fringing-from-your-photos.
NOISY PICTURES One of the major
difference between a consumer digital camera and a digital Single Lens
(DSLR) is that the former produces images with a lot of noise when
ISOs and long exposure times, and the latter is practically noise-free
(though high ISO performance varies depending on camera manufacturer
and model). Noise
is apparent by the presence of color speckles where there should be
example, instead of a blue sky, you notice faint pink, purple and
speckles amongst the otherwise blue sky. read AT http://www.photoxels.com/tutorial_noise.html
The term for an out-of-focus purple "ghost" image on a photograph is "Purple Fringing."
This is fairly common in Digital Photography.
In order to minimize instances of purple fringing you may incorporate the following:
Avoid shooting with big aperture (Small /f number) in high contrast compositions.
Avoid overexposing highlights (e.g. bright sky behind dark objects).
Shoot with a UV/Skylight Filter or a Circular Polarizing Filter. These protect the lens and also help to Get bluer skies and cut glare off reflective objects.
You could also use Post-processing to remove purple fringing by scaling the fringed color channel. This can be done in an image editor like Photoshop.
These suggestions will help in minimizing the instances of color displacement for you.
I will look forward to your feedback and positive rating.
The spots are dust on your sensor. You can clean these yourself but you must learn the techniques first. Google the words...cleaning a DSLR sensor. You will be taken to sites which will explain in detail how to do it and what supplies you will need. It may seem daunting at first, but it is really easy once you know how.
Check your picture settings, the wrong setting for the time of day or object can definetly throw off the appearance of your pictures. Plus, you may have accidentally set it to "warm" instead of auto or black and white, etc. Warm pictures have a reddish tint to them just as the cool have a blue tint. Also I have found the "night setting" only takes really good pictures if you are close to the subject otherwise it is pretty dark!
Canon fixed it without charge (outside the warranty). It's a well-known CCD malfunction that occurs mostly if the camera is used in hot or humid climate. Canon tech support was very helpful (by email) and even paid postage both ways.
Have you tried viewing the photos on a computer or printing them? There should also be parts of the menu/setting displays that would be white. The text on the image info should be in white. If you are getting white, it would suggest your whitebalance isn't set correctly. If everything has a purple tint to it, check your LCD display settings, otherwise it may be the screen is failing.
