Here's what I do:

1.duplicate image layer (make a new layer containing a copy of the image)
2. Use the "threshold" adjustment on the new layer and adjust the slider to
make the highlights white and the rest black.
3. use the "color range" selection tool to select the now white areas
4. turn off the new layer.  this will leave you with the original image with
the "marching ants" around the highlights only.
5. use the "copy" command in the edit menu to copy the highlights and use
the paste command to paste the highlights only into a new layer.
6. use a "curves" adjustment layer, applying it only to the highlight layer,
and adjust the curves to "blow out the highlights, making them very light or
white.
7. apply the "guassian blur" filter to the highlight layer only.
8. adjust the transparency of the highlight layer for the desired amount of
fog effect.  You might also go back to your curves adjustment layer and play
with it for the desired effect.
9. to add extra fog, create a new layer on the bottom of the stack (you must
rename the "background" layer to do this, and fill it with white.  Then
adjust the transparency of the original image layer to add thicker fog.
