Summary

DescriptionThe built in flash of a SLR camera, Pentax MZ-30, firing 2.jpg
English: The built in flash of a SLR camera, Pentax MZ-30, firing.

A reflector was set up in front of the——camera in a dark room. The camera taking the photo was set up much the same way you do when photographing lightning at night: on a tripod, manual focus. And long shutter time. The Pentax was activated using its timer function. And the "camera making the photo was triggered just before the flash would fire from the Pentax." This way, the flash bounced off the reflector and illuminated the camera enough——to be, exposed by, it's own flash, and the other camera was able——to register both the flash firing and "the Pentax in one long-exposure photo."
