I'm not seeing evidence of camera shake there. It's not properly focused (focus just behind) but it's a shot of a dull brown bird on a dull grey day, and it's a big enlargement.
Get closer/bigger lens, don't crop, get some decent light in there, and hone your post processing technique. Birding's not easy though
Invariably with these types of shot you have a small bird, high up a tree and backlit just to make things more difficult. I'm just getting used to the 70-300 AFS VR lens but I don't think it is quite cutting it in these circumstances.
The essential EXIF data shows:
Camera-Specific Properties:
Camera Model: NIKON D80
Maximum Lens Aperture: f/5.7
Sensing Method: One-Chip Color Area
Focal Length (35mm Equiv): 450 mm
Image-Specific Properties:
Image Created: 2010:05:03 16:16:52
Exposure Time: 1/400 sec
F-Number: f/5.6
Exposure Program: Normal Program
ISO Speed Rating: 200
Exposure Bias: 1.3 EV
Metering Mode: Spot
My reckoning was as follows:-
1) Highly backlit subject hence the +1.3 EV compensation
2) Spot metering - so the camera would be adapting more for the subject
3) Shutter speed - 1/400 sec so shake should not be a problem ( I also had VR switched on)
4) I had 'auto ISO' on the camera appears to have chosen ISO200
Is my logic wrong entirely here, would I have got a better picture with other settings? I know reach is becoming an issue so some new glass may help but I need to improve my settings and what to use first.
