Yes, what IS an intervalometer? I had never heard of one until I asked about an interesting situation I had during one gathering at the photography meetup I’m a member of.
Here’s how I learned about this funky piece of camera equipment. I had just started hooping (which I encourage you take take a look at that blog), and wanted to take timed pictures at regular intervals for, say one minute, every fifteen second. I had attempted to set this up with my Canon 7D, only to learn that I could take one shot per timer and had to reset every time I wanted a new exposure. I needed a solution.
I presented my dilemma to Blake, a fellow photographer, at the photo meetup. He suggested I purchase an intervalometer. Eh? I had never heard of it, and it was a mouthful to say, but I went to Amazon and did a search. It turns out, there are quite a few on the market!
I decided to purchase the one above: Apurture’s version of an intervalometer. I read the specifications, it met my needs, and it would get to me quickly. Neato!
I read the instructions that came with the intervalometer. It acts a a remote shutter, a timer that would take photos at regular intervals (sweet), and would work great for time-lapse photos and a bunch of other stuff. I was pleased with my purchase.
I decided to put my intervalometer to work during a trip to the woods, during which I had brought my hoops along. I got some great shots! Here’s my favorite I got using the regular timer interval shutter release, say I had it take photos for one minute at 15 second intervals.

I also set the intervalometer to take long exposure photos over a set amount of time that same day to take photos of me using an LED hoop. Here’s one of the best below.

Next, I want to share a good one I took last year at French Creek State Park, Elverson, PA, USA. When taking self portraits with an intervalometer, you have to mindful of when the shutter is going to release so you can pose yourself properly.

Lastly, my intervalometer was a boon when it came to astrophotography during the same year in that same trip to the woods I took the first photos with. I set it my camera to manual, the intervalometer to take one photo for a 3o second timed exposure. For my first attempt at astrophotography, it’s not too bad!

I hope I have shown you a few things you can learn from this handy piece of gear. They usually range from $20 on up, depending on the features and compatibility you need. Intervalometers are cool. I’m so glad I spoke up at that meetup and asked about my dilemma. Thanks, Blake!
