I'm having a little trouble with halos in some of my late evening florida sun photos. Here is an unedited (except for unsharp mask) photo example. Can anyone help with some CS5 or shooting tips? The player in the background is the one I'm concentrating on.

If you re-post the image and click the "store original" box it will allow people to download the image and view at full size to help determine the problem. Its very hard to see what your problem is from these posted thumbnails here.
Must of what I see here appears to be just sun glare from the angle of the sun.

There is definitely some chromatic abberation in that image. Its most noticeable around the helmet and face guard. Many PP software programs have the ability to remove it. I have never had the need myself so I don't know the exact process, but I am sure someone on here will be able to help you out with it.
Good luck!

Here is a good video describing Transverse Chromatic Aberration and how to correct it in PS.

Fixing these problems is certainly one matter. Is there a technique to prevent this from happening in the original image?

A higher quality lens. I shoot only L glass in my canon now. Haven't had the problem since.

It boils down to the ability of the lens to compensate for the fact that different wavelengths of light are bent to different degrees at each glass/air interface. Think of a prism splitting light into a spectrum. Generally, the better the lens the less chromatic aberration.

Wide-angle zooms are worst for this, but the better the lens, the less CA you will get. It's easy to fix in LR4, just one click.

I had this problem a couple of years ago. I have a Tokina 80-200 f2.8 and thought it was the lens so I replaced the lens with a Nikon 80-200 f2.8. I still had the same problem.I was shooting with my lens wide open F2.8. I found that on a bright sunny day by stopping down to say f4.0 seemed to have corrected this. So I am not convinced that it was the lens.I also found a way to correct the problem when it does happen in photoshop. It was very frustrating when it did happen.

Good video. I will have to give this a try. It seems to be easier and faster than my way to correct this problem. Thanks for sharing.

I looked at the full size file of your shot. It does have a minor halo, which I think was introduced in sharpening. There are a number of ways to avoid this.

1. Sharpen with the unsharp mask as usual.

2. Go to edit menu. Fade the effect slightly.

3. drop down lower in the window that opened and in "mode" choose luminosity. This should allow you to sharpen more without halo or ghosting.

Another method is to use high pass sharpening.

1. Create a new layer from the background.

2. In the upper left of the Layer box you can select the mode. Any of the following will work: overlay. soft light, hard light, vivid light. I suggest soft light, because that is the one that will allow you to sharpen the most without introducing artifacts unique to sharpening.

3. Go to filter, other, high pass.

4. In the window that opened for high pass, set the radius by puling the slider to the right. The effect is seen immediately on your picture, allowing you to choose exactly the amount of sharpening you need. Soft light mode will allow you at least a radius of 11, possibly more.

Lastly, is all you have is a halo, and you otherwise really like the picture, you can magnify the image and undertake the tedious task of cloning out the halo from the edges. Admittedly, this takes enough work, that for most people it is a labor of love.

Thanks! It was there before the unsharp mask. I can send another example if you'd like but will try your method! thanks for taking the time to look and reply!!!
