Thanks Jim; I spot metered on the birds body and placed that reading on about zone 6 and 3/4. That gave be solid detail in the whites without burning the highlights. This works for me on most white birds. I meter textured snow pretty much the same way using zone 7.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
