Bird Photography - distance from subject.
Hi, I hope this doesn't seem like to much of a strange question. I've seen some wonderful images on this website in the Avian section and most images seem to have very little cropping, so almost full frame. I'm using the 7D with a 100-400mm lens and wondered what distance do you guys typically shoot from between the camera and the subject? It's obviously a fine art getting close enough which I do seem to find difficult, but generally, what do you try and aim for, for the best results. Any tips would be great. For example, if I was to take an image of a blue tit from say 5 meters aways, the bird still looks small in the image so quite a large crop is still needed.
Any advice.
Thanks a lot.
Simon
