Yesterday I took my second trip to our little zoo here in San Jose to practice photographing animals in preparation for our trip to Africa. When I got home, I found that many of my photos were blurry. This was a very valuable experience, because, for the first time I really understand that my shutter speed needs to be larger than the inverse of my focal distance. It seems that the only way that I can accomplish this is to set my shutter speed and then use auto ISO. After I returned home, I took a few shots using this approach and they look sharp and bright, even though the ISO went as high as 6400 when shooting a shady area.
Here are a few from the zoo that came out o.k.
