A while back I had written about my favorite long exposure photography app. Well, I have a new one. It’s called Slower Shutter and it was actually written by a friend of mine, Mike Wong who works over at Lynda.com.
Note: The app is for the iPhone only. Why you ask? Because Mike is an iPhone user, and he wanted to write an app that he could use himself.
Why Do We Need Long Exposure Apps?
I love long exposure photography. But there’s a lot of trial and error when it comes to using Neutral Density filters. You have to figure out what the right shutter speed is for a long exposure based on the density of the filter you put on. Normally, your camera does that for you, but when you have a filter on, that doesn’t really work.
That’s where a good long exposure app comes in. Basically, you take all your filters off. You put your camera on Aperture Priority mode and take a photo (or just press your shutter half-way down) to get a shutter speed reading.
Then, you open your app, plug in your shutter speed as well as the type of neutral density filter you’re using, and it gives you a new shutter speed to use to get the same exposure that you did without the filter on.
Then you put your ND filter on. Switch over to Manual mode and use the same aperture as before. Finally, just change the shutter speed the the one that the app gave you.
Why I Like Slower Shutter Better?
For starters it was written but a good friend of mine 🙂 And don’t get me wrong, ND Timer was a great app, but one thing always bugged me. It didn’t have a timer in it. So I always had to use my watch or the timer app on my phone. Slower shutter has a timer built in so now I have one app to do it all.
Here’s a couple of screen captures from the app.
Edit: I just realized (thanks to Ray in the comments), that ND Timer does have a timer. I’m not sure if it didn’t used to have one, or I just missed it (most likely the latter) but it does indeed have a timer. That said, I still like the timer in Slower Shutter a little better.
Want to Learn More About Long Exposure Photography?
If you’re new to this long exposure photography stuff, and none of this ND filter talk makes sense to you then you may want to check out my Creative Live course on Long Exposure Photography. It’s been really popular and I can’t tell you how much great feedback I’ve gotten from it.
Have a good one!
