Totally in camera, hand held. Truth be known, it was totally accidental. I had been shooting some in camera multiple exposures set to 10 exposures and the 11th is the compilation of the 10. I just happened to look at some of the frames because I was documenting the new roof installation for insurance purposes when I realized I'd forgotten to turn off the multi feature...but I can see some great uses for this feature, even handheld...maybe even better than on a tripod.
