These little birds are great, I love photographing them 'cos they're so brave and inquisitive,
You want to try some selective noise reduction Martin, just running it on the back ground and not the bird itself.Well spotted Roy. It was passed through noiseware and I've just checked the original and the chest it a wee bit sharper, although the background is noisier. As you say the DOF is about 2mm at that distance
