yash3339, May 16, 2017 : A week back, we did a quick guide on how the manual camera mode on a lot of smartphones is a potent yet underused tool. Today we'd like to focus on one specific control that can get you some truly interesting results -- long exposure (or slow shutter). We used the OnePlus 3 to shoot some long exposure pictures (trust me, we hardly put a lot of effort in taking these pictures), which turned out surprisingly nice and share-worthy (which is why, this guide!). So let's quickly go through some sample shots, and talk about the details of each of them. Picture #1 Notice how the smoke looks unnaturally seamless? It's because how the long exposure shot combined 2-3 seconds of activity in one frame. Of course, the rest of the objects need to be absolutely stationary to ensure a good result. Picture #2 Same situation, a few different parameters. Here, I asked the subject to use a light source (phone flash) and move it around a bit to create what they call a 'light painting'. Picture #3 Cliched, yet a classic. We held a OnePlus 3 on a rail (in the hand, no tripod!) and this is what we got. Of course, you can play around with the parameters to get all kinds of fascinating pictures here! Picture #4 Another fun picture. My cousin here attempted to 'light paint' his name using a smartphone's LED flash, covered with his finger (which is where the red comes from!). You see, there's virtually no limit to how creative you can be with this feature! You don't even need to head out of your home to try this. A couple of things to keep in mind while attempting long exposure pictures: The smartphone should be absolutely stable. Unless you have rock-solid hands, resting the phone on a stationary object (or even better, a tripod) is recommended. Balance between ISO and shutter speed: It's important to note that the sensor allows a lot of light in every second, so you need to be wise selecting the shutter speed. 2-6 seconds is usually enough, unless you're shooting in a LOT of darkness. Also, a low ISO is recommended; usually ISO 100 does the job. I hope this little guide helped you. If you do play around with the feature, let us know of your creations in this thread below. Be sure to share the exact parameters and share the info with fellow forum members!
