Hi, I have been getting into bird photography since the beginning of this year. I am shooting with a 7D and 100-400 L. Attached is a recent exposure (I have attached both my processed version and the original RAW). This is probably not my best work, certainly not my worst. What I am looking for is a critique of my exposure technique (what you can infer), the image itself, and the processing. Feel free to download the RAW and post an example of how you think I should have processed it (please include a basic write up of what you did).
I am just looking for opinions and suggestions on how I can improve and hone my skills.
Some details about my technique. This was taken about 7-10 feet from the female red-winged blackbird at about 6PM. I used AF Servo, single point AF, Spot metering, ETTR (as much as I dared), and IS to achieve this shot at 1/800s, f/8.0, ISO 800 @ 400mm. I processed the image completely in Lightroom 4. I cropped, adjusted WB, and globally sharpened, then applied the following local adjustments: highlight recovery, contrast, and applied NR.
