My flickr contact kenny created this excellent double exposure of an amusement park ride in Malaysia with his Ricoh GRD IV.
Double exposure is a skill and takes practice. The Ricoh GR (and I assume earlier GRD series) make it easy to do so it’s just a matter of finding suitable subject matter and trying it out. Note to self: do more of this, it’s fun.
Flickr member Greg Raiten took this in Santa Cruz, California.
It’s unusual to see images of this ride in monochrome, usually they’re in color with long exposures to get a sense of movement. This image is unusual and it works well.
Flickr member Ivan Dostál took these great images of a swing ride at a fair with his Canon 6D.
I don’t know where these excellent images were shot, sorry. I wish folks would post things like that but not everyone does.
