That’s a great technique I did that too. But with digital and the ability to stack images later you don’t have to do that in-camera anymore. So what I do now is set the exposure to between 5-8 seconds and set the drive to continuous then I just lock the cable release and let it go.

The Panasonic Lumix G5 doesn’t have time-lapse. It does have shutter delay (2s or 10s), burst mode and single-shot mode. Being a micro 4/3 camera, it doesn’t have a mirror. But, it has electronic shutter. I keep the electronic shutter on all the time, but I did notice that setting tends to adjust the ISO for lighting conditions.
Back when I learned on film, the technique I had for shooting fireworks involved the bulb setting. I had a Pentax K-1000, which is a very simple manual-everything camera. I purchased a tripod and cable release for it. I set up directly under the fireworks and pointed the camera where I knew they would be. Leaving the lens cap on, I set on bulb and opened the shutter and locked it open using the cable release. When the fireworks go up, I removed the lens cap and wait until the fireworks burn out. Put lens cap on and advance the film. Sometimes I didn’t advance the film between fireworks. This made for interesting double exposures. BTW, I didn’t mention this was using the 50mm kit lens and slide film! I’m glad Kodachrome retained its colors over the years. The 2 samples I attached are from 1985 over Lake Nasworthy near San Angelo, Texas. https://uploads.disquscdn.com/images/b73f88e42a67d7005ca5c19b08cb54a2ce935b45ff2fac2303dd979ce4cab410.jpg https://uploads.disquscdn.com/images/799662f4e3f543f9dc49cb1a44373638ec72dc015d7dc4209ee1fa2038d17ab4.jpg

@disqus_QY2UANdX4M:disqus good points! Does your camera not have time-lapse settings built into the menu options? My Fuji does. So I just dial it in there and don’t need the extra fancy remote. As for bulb yes that is correct – but for fireworks and light painting I usually set it to 3-8 seconds for fireworks and whatever is needed for light painting. Astro photography might need bulb if your camera only goes to 30 seconds though – that’s when I use it, when the camera can’t count that long.
