Arnt - Those are great --- and I have to respectfully disagree, it is definitely challenging photography. When you are shooting a white bird in broad daylight, it is quite a trick to get the exposure right. Using centre-weighted metering will often do the job, but you still have to pay close attention to the histogram. With the snowys, I had an easier job when it was overcast, but the sunny days gave the best shots when I occasionally managed to do it right.
