I am using Photoshop CS2. Shoot my images in RAW format. I shot images of a white egret against a black background.

All of the images have a green halo around the top of the bird’s white head.

This halo was not caused by the sharpening tool.

Can anyone instruct me how to remove this halo so that I can print the image.

Thank you for any help or suggestions

Basically, photoshop is adding +95 of red to the pure blue image. That’s a lot of red!

The change is caused by a conversion from one proifle to another.

Check you colour settings. Set your colour management policy to "Preserve" (for every colour mode) and to ask when opening, pasting if there’s a profile mismatch or a missing profile

George, maybe you are seeing chromatic abberation from your lens. try acrs lens tab and slide the various sliders to get rid of the halo. i usually zoom in to at least 100percent or greater to see the trouble area.

Is it normal on this forum for people to jump in with all sorts of other, unrelated problems?

It really distracts from my original question and on many forums, its considered quite rude, or even banned completely.

It’s discouraged, but what can you do?

Meanwhile, my last post was addressed to you

I also suggest you read up on colour management. This is a good place to start: <http://www.gballard.net/psd.html>

And get back to us on your colour settings and the profile embedded in you file.

Thanks. I did reply, by the way. By "blue" in photoshop, I mean B=255,R=0,G=0. That is what looks purple.

I also said "Sorry, I don’t know what you mean by "can you give us… the colour profile of your file." Please can you explain what you mean?"

I have re-calibrated with the Huey countless times now. Deleted all the profiles and started again… and again and again. Uninstalled it, reinstalled it countless times. Tried different graphic drivers, different monitor settings and color temps. Nothing I have tried seems to fix this problem.

Here’s how a blue (B=255,R=0,G=0) gradient looks in PS. See how purple the light blues are. And see how blue looks in Windows, compared to photoshop. Of course I can get the same blue in photoshop by loading the monitor’s profile, but that just disables colour management and is not the right solution.

If there is a problem with the Huey as mentioned in post 3 The profile will be wrong no matter how many times you calibrate it. I would take it back and and get an EyeOne2.

"If there is a problem with the Huey as mentioned in post 3 The profile will be wrong no matter how many times you calibrate it. I would take it back and and get an EyeOne2."

Indeed. On the other hand if there is nothing wrong with the Huey I will then be wasting more money on an EyeOne2 and the problem still won’t be fixed.

I’d rather work out what the problem is before just throwing money at it.

Please can you explain what you mean?

A colour profile is not a colour value.

Did you check out the link I provided?

This is aother good place to read up on Colour Management:

What happens when you load a canned LCD profile as your system display profile? If you get a normal blue then it’s the Huey that’s at fault or you have a laptop.

I have a 2000 Pismo Powerbook and get the same purplish blue calibrating with an EyeOne Display for OS 9.2.2, but this display uses a low quality TN panel.

I have the same problem with Photoshop… things that are blue in every other image program (Microsoft Photo Editor, Breeze Browser, Windows Explorer, Kodak, real life, etc) turn up purple in Photoshop.

This is with using the same monitor, as well as using two different monitors, as well as with a different computer (a desktop and a laptop).

Therefore, it doesn’t appear to be monitor calibration to me, since the blues are rendered as blue on every other image program on every monitor/computer combo tested… and the blues are purple when opened in Photoshop and/or ImageReady, again, in every computer/monitor combo tested.

I’ve searched for "blue purple", and found this thread. I’ll continue searching, and hope to find an answer. If I do, I’ll be sure and report it back to you if it will help. I doubt it is your calibrator. I suspect it has something to do with how Adobe interprets the images.

ON EDIT: I noticed the same blue turning purple issue in Photoshop 7 as well as my current CS2.

I’m having the same issue with my new monitor (HP3065 LCD), except that I’m calibrating with a Spyder 2 – hoping that the original poster figured it out the problem? I am very frustrated with this too. I’ve deleted my old profiles, calibrated countless times, etc. When I set proofing in photoshop to view the monitor settings I can see the same color as my desktop. Otherwise my images are very blue.

I also have a huey and have the same blue-purple problem.

Any solutions yet? What did you do Ron?

Have all you purple guys made sure Adobe Gamma Loader has been eliminated from your Startup Menu?

If it’s still there, it will try to load another profile which will conflict with the one created by your Spyder/Huey/Whathaveyou.
