Thanks, guys for the advice. I tried to implement most of it, but to get
closer I had to lose the tripod. This is from about 30 feet.

I think this is a huge improvement, but I still have to work on exposure as
the head seems to be burned out.

If you are referring to this shot:

Then, yes it is at least a full stop overexposed. Darned nice shot, though!

Nice. Big improvement! If you shot raw, it's probably possible to
recover the highlights in the head.

No way. Overexposed is "clipped" and beyond recovery.

It's amazing what you can squeeze out of a raw file. Even in that jpeg
there's only 1/3 of the head totally blown out in the middle.

This is true. In fact, I was able with Capture NX to reduce the exposure a
full stop and recover most of the head feathers.

Here is the corrected image:

Nice, very nice. Where was this taken?

At our home in Belfair, Washington on Hood Canal (not a canal; it is a
fjord). These bald eagles nest in our back yard and frequently come down to
the front to hunt, bathe in the creek, and eat whatever it is they catch.

I don't understand your need to use NX then edit in CS2. In the process the
exif info may be effected. Definitely the fucus point is wiped out. Just
trying to understand what mode you are shooting in and what metering mode
was used,what iso setting and what exactly was the focus point.

That said, a very much better shot!

I wouldn't be so quick to declare that.
It's amazing what can be recovered using RAW.
You can recover more than one-stop from most highlights... This may well be
mostly recovered, if not fully, and fully is a real possibility.

Not neccesarily. Mostly you'll find that one channel at least retains
detail, even when two are blown out. A good RAW converter can use the
detail in one channel to recreate detail in the other two and at least
partially restore the highlight.

This is a major reason to shoot raw.

Good point ... I stand corrected.
