I'm not sure if this is strictly "panning" because it looks as if the subject is on a merry-go-round, which would suggest that the subject is sitting/standing still in front of the camera which is held still, while the background scenery is spinning. Anyway, it's a fun photo and it has great character.
I like this shot and I think this technique is a smart way to pan. Very effective. The boy's expression and hat spikes contrasting with the background really make this fun.
This photograph is a very good example of panning. The is an excellent range of values in this photograph. I also like how the subject is slightly off center.
I cant understand the physics of this picture. If he is moving what about his hat hair, his ears covers, all is static. I think u make some efect like movement blur, not allowed in basic editing.
