Hi guys. I seem to be plagued by this fringing problem. How do I fix it and is it caused by the camera, the lens (is it a bad lens that does this?), or just one of those things? Do I have to just put up with it and turn the pic into a b&w? Is it worse at different zooms and/or apertures? Will a filter fix it?

Canon 50D, 28-135 EF IS USM

It's what is known as purple fringe or Chromatic aberration. It's usually caused by less well made lenses. The coatings that are used on newer lenses help to reduce this. It can be easily fixed in PP using Photoshop or Paint Shop Pro or whatever photo editing software you have at your disposal.
Hope this helps.

real quick fix..there's still a little purple showing

Can you explain how you achieved this result? I have PS pro and didn't get this good a result.

both images are cool - the b&w becomes a nice graphic and the color image is well done - nice composition and such and as for the fringing
the only person who is going to see it - is you. I mean were you to print the image and display it I'd bet you no one would notice that.....

still if it bugs you so darn much buy better glass

I'd like to correct one thing; it's not a matter of "better glass" as even very expensive lenses are plagued with this condition to varying degrees.

It's a matter of shooting high contrast at large apertures...usually the situation you posted about is very very tough to deal with.

Also, Lightroom will fix this pretty automatically also.


Sadly, it's a fact of lens life :(

How to fix fringing for dummies: There are proper ways to do this but I do not have the patience nor the time.

If you have lightroom 4.1., They put in a fix that actually works this time. It will work for this photo. It is under "lens correction".

If you have photoshop cs5 or 6 or elements, simply go to "hue/saturation" and use this tool. It is quick and dirty.

With the photo open, and the hue/saturation at the ready, click on the master drop down box and pick the colour that you want to fix. The click on the small eyedropper.

Oh, I forgot to mention one important thing: Have the photo blown up large enough to easily see the fringing first. It does not have to be perfectly clear at this point.

Back to the other step: Place your eyedropper directly over the colour that you want removed and click. Then move the saturation slider to the left until it disappears. Repeat this process with other colours as needed. It is that simple!

A word of caution! Be careful of the same colours in your photo as the fringing. Watch out as you are moving that slider. If you overdo it, (red for example) the reds that you do not want affected will diminish also.

To prevent this, simply isolate the area you are working on and this will not be a problem.

True - most of the time _ some times we photographers see an image that just cries to be shot and it is in the "wrong" position with the "rule" of don't shoot into the sun.
Takes some PP but turns out the way we wanted to see it in our photo collection.

It seems to be the first one I remember being told when I got my Brownie at age 10yrs. seemed like a good bit of advice at the time. LOL

Is it just me? I love the B&W version of this photo.

I'd bet you could sell that, frame, mat, and sell.

Wouldn't mess with the Crhomatic abberation on this one at all.
