Finally!!
by Dottie Short
This is the first success that I've gotten shooting a moving target. I finally took the advice of an expert and chose the 19 point focus on my 7D. I didn't think it would work, but much to my surprise it did. The weather that day was rainy and gray so the BG is not too interesting. I'm seeking suggestions as to how I can improve.
7D - 100-400 mm @400 mm
1/640 F5.6 ISO 800
Gitzo tripod w/ Acratec gimble+ballhead
Small crop (forgot how to figure %)
PP CS4 and Nik
I forgot to mention that I over-exposed by 1-2/3

From the look of the larger version, I would say this shot was tack sharp or close to it in-camera. So, it should not take much sharpening in post-processing to make it look perfect, but the larger image looks a bit over sharpened. I would try backing off on the sharpening a bit. Also, the contrast is very high, which might in part be due to the sharpening applied to the image. I would reduce the sharpening a bit.
Did you lighten up the shadows in post-processing, there is a bit more noise in the shadow parts of the bird than I would expect with the 7D and very little crop.
If I may suggest a few things relating to consistently getting sharp bird in flight images. First, it really helps to shoot on days with good light conditions so you can keep your shutter speed up over 1/1250s minimum. Fast shutter speeds help so much. However, you still need to pan at very close to the same speed as the bird. So, I like using just the center focus point, or center point with assist points surrounding the center point. It is much easier to keep the one focus point on the target and move at the same speed as the target than to have all the focus points lit up and try and pan at the correct speed. Also, if you try and use all 19 focus points to get a bird in flight and the BG is a busy one (i.e., not blue sky) then the AF will have a tough time picking the bird and not the BG. With just the center point and you keeping the point on the bird the camera will focus on the bird with no interference from any BG elements. If you know you will be shooting against the blue sky then the center point with assist points works very well.
IMO, the key to consistently sharp BIF shots is to get good at keeping that center focus point on the bird as you pan. Better yet, get good at keeping the center focus point on a particular spot on the bird, like the bird's breast as you pan the entire series of shots as it flys by. If you can do that you are panning at the speed of the bird and you will get a lot of sharp images.
There is no substitute for practice. The best AF and the most AF points in the world will not substitute for being good at quickly acquiring the bird in your viewfinder and being able to pan at the exact speed of the bird. Oh, and I def agree with Keith, manual exposure is the only way to go for flight shots for the exact reason stated by Keith.
Just some suggestions. Keep up the good work.
Lets see some more
practice, practice, and more practice. Great advice already from Ron and the others.
