This is my first attempt at slow sync flash to capture light trails and freeze the moving object with 2nd curtain flash. Why does the horse and carriage appear as ghost image?
Is the flash power too low? Is the object out of flash range? I can't remember the distance between the camera and the object but my wild guess is it's at least 25 feet (I'm very bad with distances so I could be completely off). I was standing on the sidewalk on a 2-way street in Riverside, California.
Settings are as follows:
Rebel T2i, 11mm, ISO100, f/8, 2 sec. Second curtain flash.
