how do you fix purple fringing pp?

[jann1033]

have camera raw 4.0 and digital photo pro for raw conversion and ps elements 5...can i do it in any of these and how do i do it...before i get rid of my now sharp but still to purple 28-135 lens( yeah i know i am a glutton for punishment) i want to see if i can correct the purple since i keep reading it's an easy fix. since it's sharp i would be happy if i can fix the purple even though it 's a paiin in the neck step....that way i can limit my new lens choice to super wide and not feel guilty about it.
am i right that it's high contrast that increases the fringing, it seems pretty much at all apertures/iso although maybe a little worse at 28, to me but definitely worse in light to dark situations
thanks

This is the ACR in CS2

You move the two highlighted Sliders away from the color giving you issues, make sure you zoom to at least a 100% view so you can see the fringing move. The goal is to line up the color with the subject.

Note this fringing was not there You can see I moved the slider all the way to the left to show you an example

i do not have that setting....but thanks anyway. i'll have to get out my missing manual book and see if there is anything there similar

does your software have a help file//

with paint shop pro, there is a special purple fringe adjustment

I would guess that is one of the features left off of Elements.

I found a trick on a web site (which I don't remember where it was, so I can't bookmark), but basically, since purple fringing is generally an area of very high contrast, an easy way to fix it is to basically make that area black and white.

Go to Photoshop and select the Sponge tool, which by default, is set to desaturate. Go to an area of purple fringing and start using the tool, and the purple will lose its color and will usually blend nicely with its surroundings.

I found that this worked well for me in a shot where I got a little PF with bright silver next to black. Pretty quick 'n' easy - I'm not sure that it will work with all PF issues, but it's easy enough that it's worth a try, IMHO. Good luck!

Sorry about this question but I am trying to find the purple fringing in this picture. As I've never noticed pf before, I have no idea what I am looking for. Is it the line along the top part of the arm? What really does cause this? I can't say as though I have ever noticed it in any photos before, but maybe it was there and I wasn't tuned in to it.

If you look closely the fringing runs along the entire white sleeve on the sunny side. This is not a SEVERE example, as it did not have any fringing to begin with I made the fringing appear for demonstration. Remember that the view you are looking at is fully zoomed in to 100%, so it may not show in any prints but it is still there.

Ok, thats what I figured you were looking at. I'll have to keep an eye out for it. Is it true that it seems to happen in areas of extreme contrast?

Thanks for the explanation.

when i see it is only with my 28-135 lens, along a white/very dark area..ie a white house with a dark shadow by the roof edge or a white house/light sky ie gray winter cloudy with a dark leafless tree in front...mine was so bad with this lens it was on both sides of the entire branch etc....from what i have been reading, it's usually by blown highlights but according to my histogram these places weren't blown...it's due to the lens not focusing all the wave lengths at one point ( i think ) which is why i think they did something wrong the first time they tried to fix my lens...this last repair seems much better though i'm going to go out and see if i can test it more today. it can also be something called sensor blooming but i don't think that's the problem due to none of my other lenses doing it
i took a few experimetal shots with a little fringing so i'll try the desaturation thing groucho. still haven't remembered to look in my missing manual book

i was wondering if adjusting the color place in my camera would help.ie the magenta what ever scale you can move a little bit. i already have it slightly underexposed but am trying to figure out if there is anyway i can compensate for this in the camera...any ideas? i mean other than never shooting another white area with something dark by it?

 

[Groucho]

I think some of the PF can also be caused, or at least, aggravated by the sensor... ie, the same lens taking the same pic might not cause the same PF if you're using a film camera. Someone can feel free to correct me if I'm wrong on that one. I don't think it's a "good sensor vs bad sensor" thing, just the nature of the beast - possible Sigma's Foveon sensor might have an advantage here?

Anyway, I did a quick before-n-after of the picture I was talking about and how the "sponge" tool in Photoshop looks. These are 100% crops.

Before:

After:

Something about that bright-vs-dark really brought it out, it's something that I had very rarely seen before but this pic really demonstrates it. Of course, I'm sure that it's one of those things that the more you look for it, the more you notice it.

there is a one step purple fringe fix...I tried it on both of these sample pix and it worked very well..

Purple fringing is usually the result of chromatic aberation. It's a usually a lens issue. The problem is that the lens is focusing different wavelengths (colors) of light slightly differently. The purple light has the shortest wavelength and sometimes gets focuses far enough away from the result of the colors to start hitting new pixels. It usually shows up in high constrast areas because the light that includes the purple (the bright part of the high contrast area) is bright and it falls on an area that otherwise doesn't get much light (the dark part of the high contrast area).

Here's an article that might help with correcting:

Do you have the latest version of the Adobe Camera RAW plug in? It is the same plug in for Elements And CS2.

 

[jann1033]

i have camera raw 3.6 evidently since that 's the latest but mine says 4 in the heading?????and some how fixed some of the fringing but don't know what i did ( for some odd reason my computer was really slow and not keeping up with the things i adjusted, uninstalled elements again and it 's faster again )and can't seem to repeat it with another photo. i

i just fixed it with the color noise adjustment. Thanks!
