purple fringing in strong backlit subjects

My camera is a G5 and I find that some of my pictures show purple firing in strong backlit subjects, which has been buggung me for some time. I use RAW format for most of my pictures and don't pay much attention to setting the white balance, since it can be adjusted in photoshop. I have read in another forum that this problem is a typical with the G5. Anyone have this experience and how to lessen this effect?

This is something that plagues all p&s digital cameras. I noticed it on my Minolta d7i and then on my Canon Pro1 and was obsessed with it! But I soon discovered that it was more obvious on the computer screen but on prints it was nearly nonexistant! There are some software programs that work wonders in reducing that dreaded purple fringe, but must be used with care.

CA (Chromatic Aberration) is not exclusive to Point and Shoot cameras. It is also present on high end cameras. The Photoshop CS2 Adobe Camera RAW conversion has a tab called "Lens". In this tab there are two sliders that deal wiht Chromatic Aberration. I think the fact the CA correction feature is located there is proof that high end cameras suffer this problem (although earlier P&S cameras were much worse). If I could find some pictures from my old Gateway camera I could really show you some CA.

Actually, my G6 has very little CA. You must get down to the "pixel peeping" level to see it and even then it is minimal and only in the most contrasty areas.

I think the latest cameras have a lens coating that minimizes CA.

As I said, CS2 ACR will fix CA. I looked at Elements 3 upgraded to ACR v.3.1 and don't find it. I'm not sure about Elements 4.

Appreciate your help, you are quite right when you say the purple outline is more visibly on my monitor then on the printed picture.
Also glad to hear that this phenomina is not a typical problem with the Canon G5, infact I was actually already thinking of selling the camera because of that.

I believe the term you're referring to is 'purple fringing.'

I'll correct the thread title so people will better undersand the topic.

Under the offending circumstances, try shooting Av mode at f/5.6 - f/8.0.

fyi
Corel Paint Shop Pro X has a 1-step purple fringe removal function...

I recently posted a thread about what I thought was CA, later confirmed as purple fringing in the EF lenses section of this forum. I had horrendous purple fringing in a high contrast (branches/sky) section of a shot with using 350D and 17-85IS lens. A £1000 combination. It's not just P & S !

The only Lens I've used that experienced CA was the Canon EF-S 18-55mm. Since getting my current line up there hasn't been one occurrence of the Purple Fringe. Even my Sigma 18-125mm handled it very well. CA is why I sold my Canon A95 as it just didn't do well with PF.
