Thanks, Sunny for sharing your workshow for cleaning out noises in images at high ISO. In my case, I did not apply any denoising nor smoothing techniques to the picture posted. I didn't see any apparent and annoying noises in this particular picture. All I did was to do a slight crop, some USM and finished with the save-for-web function.
The perceived absence of details is due to the shooter's unsteady hands even at 1/125. Furthermore when I zoomed in to examine the details captured, I could see that the area at and adjacent to the forewing apex was not in sharp focus when the shot was taken.

Sighted another male A. trogon at the same location, but this time the butt has some birth defect on one hindwing revealing the yellowish-green patches on the upperside.

Hmm.. the left hindwing is completely crumpled. This individual won't last very long. Did you see it fly?
