Flock of birds

I like the additional dynamics produced by the shift of the building from frame to frame.

Would that be called a 'step pan'? In any case, I like it.

"step plan", most probably. since there ain't no natural motor drive designed for the Pentax K1000, I managed to shoot as quickly as possible. thx for your comments !

The passage of time via the shift is well done! You have created a sense of time which is often 'frozen' in still photography, but you have brought change in time forward via perspective....which is perfect!
