Octoberfest generally is an easy place for candids, but in terms of speed, especially focusing speed with longer focal lengths, it can be demanding. But the people usually don’t object being photographed. Only inside the beer halls the breweries now imposed quite strict regulations to stop the publication of images showing drunk or half-naked customers.
I am more interested in small details like those gingerbread hearts. Last year I photographed them in the food stalls where the color is really overwhelming, especially at night when the lack of light makes it easy to direct the views. The small collection of Octoberfest posts you can find here.
