You've built a camera; this is no more difficult, except it involves a different area of experience.
A "clapper" switch could, logically, do the same, with the appropriate resistor to lower the voltage to what you desired. What sort of distance were you thinking of for activating the trigger? The laser pointer would effective at a greater distance than sound.

Hmmm,
Starting to get tricky. There are all kinds of 120 V. "clapper"
switches. I wonder if they have a circut that drops voltage from line
current that could be bi-passed?
Thought of a goofy level idea. I stick the camera on a monopod and
raise it high overhead. I could have a plumb-bob down the center and it
would ground when it touched the sides of the tube.

> A latching relay is simple to make. Select a relay with one contact set (at least) that makes contact, when the relay operates, before the other side breaks contact; ie. a make-break contact set. The power/voltage to trigger the relay, after the light sensor was triggered, could go through the break contacts, and the power/voltage to hold the relay operated would go through the make contacts. I'd suggest a second, momentary relay to be triggered to reset the circuit to the original state.
