Hands on at BIF, first time. Enjoy..!!
Everything Chris R said is very good info. So try to follow his advice.
If I could inject a couple of hints here. Best light is near sunrise and sunset. At this time the light can be almost underneath the bird, and it avoids some of that dark silhouette effect I see. Also I noticed the 105mm focal length. This would be struggle for anyone. If you can get your hands on a 300, 400, or 500mm, this allows more pixels on the bird.
FWIW BIF is one of the hardest photography challenges that I know of. Don't get to frustrated with the pitfalls. Go slow and just keep learning one step at a time.
I am not exactly satisfied with my own progress so far either.
Hi ken, its the 18-105 kit lens I'm using. Couldn't get any of the lens you've mentioned. Yes, bif photography is tough, the moment you take eyes off viewfinder, there you missed a shot
