The halo reduction works well(the halo has disappeared), but the image looks a bit softer than mine(see magnified crops : http://www.juzaphoto.com/npn/halo_hnf_01.jpg
)...there can be various reasons :
- noise filtering
The original image was taken at the lowest ISO value of my D70 and it was very noise clean; moreover it has been slightly blurred in the process of resizing it from 6 megapixel to the 640x428 web version, so the "not sharpened copy" was really noiseless. If you applied some noise filtering it could have diminished the detail.
- amount of sharpnening
Mayble you have used a little less sharpening than me
- halo reduction
the halo red. algorithm might have reduced sharpness?
I think that the best test might be to try the halo reduction with the already sharpened image (to avoid the uncertainties about the amount of sharpnening) and with all the other functions (noise reduction, color,etc.) turned off.
