You can try to reduce the chromatic aberration by choosing a smaller aperture. CA is an inherent problem of digital photography.

I see a smiling humpty dumpty in your picture.

Can't remember but there's this function in photoshop that helps remove CA.

I tot CA is due to the lens? nothing to do with digital or not digital

Last time when i used consumer lens, the CA is pretty serious, but no more since I upgraded to "L" lenses.

Just checked the EXIF, since the shot was taken at f4 and nothing can be done with your F828 lens, you can stop down to f8 and try not to use the two extreme ends of the zoom. I am not sure what is the focal length of F828 lens, let's say max zoom is 5x, the sweet point should be the middle, around 2.5x

What I meant was that it is a much more serious problem with digital camera. I'm not a physicist nor do I profess to know what causes it to be more serious in digital camera but it's probably due to the way CCDs/CMOSes over-exaggerating the color fringing.

Well..for this pic try to use a smaller aperture since the background is still quite far away and should not be affected too much. Personally, I find the purple fringing ok. If you have not told me about it. I won't even take note or care about it at all. Overall, the picture is pleasing. :thumbsup:

Purple may not be that obvious on such shots but when shooting at objects with strong backlight, it can get pretty obvious. eg. shooting through leaves with a bright backdrop. The 828 seems to be extra susceptible to this.

But well, a simple Action in Photoshop will cure it.

Photoshop is not easy to use, esp considering the level of my skill now. All you need is to learn some basics.

In most (but not all) situations, PF can be drastically reduced using the following method in Photoshop Elements - choose "enhance", "adjust color", "hue/saturation". Choose the magenta channel and crank "lightness" all the way up or all the way down.

Give it a try and see if it works for you.
