Camera has a problem with purple fringing with pictures. A purple tint shows on viewer and on pictures. Color varies with subjects or objects viewed.

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.

Turn the color all the way off---examine the screen to see if black and white or screen green in areas or whole screen.

The other possible issue is tint will not vary enough from green to purple when adjusted.

Two different issues--which do you seem to have?

You're either using old/expired film, or taking photos during dusk. Color film is balanced for daylight photography. Using it under conditions other than that will result in varying color casts on the resulting images.

Fluorescent lighting: Greenish
Indoor bulbs: Reddish/orange
Outdoor at night/dusk: Blueish/purpla
Ourdoor at dawn: Pink/blue

Or, you may have just gotten bad print work done. Try a different lab.

Hi,

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.

When CCD Imager Sensor in camera got defective, camera shows such tinted view.
This part should be replaced to see normal view.
Canon has issued CCD Advisory Notice for Canon camera and offers free of cost repair.Please see details at Canon CCD Advisory.

check out your scene and macro settings. If you are in macro mode (an icon that looks like a tulip), you should be no more than 2 feet away from your subject. Also if you are in the wrong mode (night mode in daylight, or bright mode indoors, for example), your colors may appear off.
Also check to see if your digital zoom is on. If it is, and you are too far from the subject, your picture can be quite grainy. This is a great effect if you want your picture to appear as if it were an impressionist painting, but not for a crisp picture or portrait.

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.

According to many respected sources with far more expertise than myself, the symptoms you are describing also fall within the realm of Canon CCD failure. In Canon's Service Notice: CCD Image Sensor Advisory, they outline the most common symptoms (distorted images, LCD showing only a black screen, etc.). They have conveniently limited the description to the bare minimum. More symptoms of the failing CCD include: pictures appearing on LCD show up with severe color variations (pink-purplish or green tint), colored "streaks" or "lines" throughout pictures, and wavy distortions in image. Most of these symptoms include the color variations, but not always. The lines or waves can appear in any direction and with varying degrees of severity. Some LCDs do not go black, but turn totally purple. Here is a link to a very informative article that should clear up any questions you might have.

If nothing else, call the Canon Customer Support Center at 1-800-828-4040. They will ask questions to identify whether or not you are having the same symptoms as described in the Product Advisory. I have been through this twice, and both times they were very nice and very helpful. Even if you don't qualify for the free repair, it didn't cost a thing to find out.
I hope this has been helpful.
