Purple Fringing

[viewfinder]

Some pictures I take with my Canon S3 IS, have a purple haze/fringe.
Is this due to a lens defect or is it a lighting problem?
You can see what I mean by the purple fringe in the picture of the moose.
If you look at the snowbank by the moose, you can see the purple colour. It also showed up when the picture was developed.

You'll get that sometimes. Software programs can help eliminate it. If I could see a photo of the moose, I may be able to speak to it more.

1. I'm not sure if it's my comp or what, but i don't see any pictures in your post.

2. Purple fringing can be caused by many different reasons and is a problem more prevelant in point and shoot cameras like the S3. Sadly, this is a problem we have to live with. A way to minimize the effect would be to increase the Aperture number. from say 3.5 to maybe F5. This won't get rid of the problem but in most lighting conditions it will help.

Fringing generally occurs near areas of sharp contrast. Hope that helps.

I'm trying to upload the picture but, for some reason it's not attaching to my post. Hopefully, I'll figure out what I'm doing wrong.

Here is the picture of the moose.

yup. can't get much more of a sharper contrast than that. Read my above post.

One reason for PF is lens design defect in combination with lighting. You will see PF whenever there is harsh lighting contrasts; i.e. where the dark meets bright light. The best place to see PF in DCRP is the Tunnel of Doom (http://www.dcresource.com/reviews/canon/powershot_s3-review/IMG_0028.JPG). You can see PF on the palms on top right when viewing at 100%.
There is a link that you can download PF reduction software. I'm not sure how effective it is though.
It's from Fuji forum, there is a link from P_Schneider (2nd post in the thread):

Thanks for the explanations and the software link.

Holy crap!

I've tried for the last little bit, but for the life of me I can't get the moose to talk back!;););):D

If you are willing to work on the photo with software, then there are several programs which will go a long way in removing CA. I used an old version of PSP to reduce CA on your photo:

You can also significantly reduce purple fringing by stopping down your aperture (higher F stops). From about F5.0 upward should take care of most if not all of it on the S3.
