I photographed this Black-backed Dwarf Kingfisher at Kithulgala in February, 2010. I was guiding a serious bird photography tour with Felix Ng from Hong Hong and two of his friends. Felix wielded the latest Canon EOS 1D Mark iv fitted with a Canon EF 500mm F4 super telephoto Lens. After he was done, I borrowed his monster lens and coupled it with my Canon 40D to shoot this beauty. The settings I used were 1/25 and ISO800. As this bird was in a dimly lit spot, the high ISO enabled me to lighten things up to catch more detail. As expected the high ISO also resulted in rendering the image a bit grainy in the final output, which you can see especially in the background.
In order to get rid of the grainy effect resulted from camera noise, I used a camera noise removal software named Noiseware Professional for post processing. See the result below.
Noiseware Professional is a plug in filter that can be used with Photoshop and it is very easy to use. The whole operation of cleaning up the image just took me less than 30 seconds.
Edit: This is in response to flowergirl's comment in this post. The grainy effect is more obvious when you see the image zoomed in/cropped. Here's a close crop to reveal it:
And the same after filtering it through NP.
