Accelerated video and long exposure times
Within seconds, the viewer sees buildings rise and flowers sprout from the ground. Time-lapse footage gives the impression that time flies, as if the earth suddenly rotates faster than usual. If recently this type of shooting was the prerogative of professionals, now they are within everyone’s reach and can also be made with a common digital camera.
We show you how to make time-lapse videos and original photos using the effect of long exposure times. Discover our tips and experiment with new photographic techniques!
How to make a time-lapse video
The easiest way to get an accelerated video is to play it back by doubling or generally increasing its speed. However, to obtain more convincing results, it is better to make a series of individual photos, from which to start to create a movie with Time Lapse Services in Dubai. The frequency of shooting will depend on both the type of subject and the speed at which it changes. You can then take a shot by setting an interval of 5 or 10 seconds and then get a video with 24 or 30 photos per second.
Which camera to use?
All types of cameras are capable of taking time-lapse footage. It doesn’t matter if it’s an SLR, a compact or a mirrorless – the only thing that really matters is that it has a manual exposure mode (on cameras this is indicated with the M symbol). Action cameras are usually already equipped with a special timer or a particular mode for making interval shots, making the making of this type of video even easier. With the help of an app you will be able to take time-lapse shots even with your iPhone or Android device.
In the settings you can “set” the exposure time. This is especially true for shots taken at sunset, if you want to avoid having to continually change exposure as the darkness intensifies. (Without these adjustments, you would get unpleasant changes in brightness in the final shot). Also from this point of view, smartphones show their
limits and reflex cameras show that they can respond to these needs in a much better way. On the other hand, smartphones are smaller and easier to carry. Just change a couple of settings and you can start the photo shoot.
Before starting: the necessary equipment
Regardless of the chosen camera, it is useful to use a tripod or, alternatively, to use a stable support point, so that the camera always remains in the exact same position. This prevents blurry photos from being taken.
Also check that the battery is fully charged and that the memory card has enough space available.
Inspirations: subjects and shots
The world we live in is constantly changing: practically everything around us can become the protagonist of our shots. Of course, images of landscapes with ever-shifting clouds, as well as sunsets taken during the “blue hour”, are easier to photograph than buildings under construction. Shooting of budding flowers, on the other hand, has a guaranteed effect. Road junctions during dusk or a moving ship also lend themselves perfectly to this technique. The only essential requirement is that all photos are taken from one location.
For an even more intense result, try moving the camera while shooting. Smaller models can, for example, be comfortably fixed on an hourglass.
Camera settings for time-lapse video
After positioning the tripod and choosing the right shot, you need to proceed by setting the parameters of the aperture and ISO value. We recommend using a fairly large aperture (small aperture value) and possibly a low ISO value (50 – 200). Before shooting, remember to set your camera to manual mode, avoid making these changes once shooting has started. During the first field experiments it is useful to use only the JPG format. Partly because there is enough memory space to save a large number of images, and partly because importing and subsequent processing will be faster than massive RAW files.
Choose the shooting frequency
A smooth video requires 24 (or better yet 30) frames per second (fps). The real question to ask is therefore at what interval the camera will have to take the individual images to achieve a good result. The best solution is to experiment as much as possible, because the speed at which the subject changes also dictates how many photos should be taken per second or per hour. You could start with an interval of 1 to 5 seconds to photograph people in the street or in a square. An interval of 5 to 15 seconds is suitable for shooting in sunlight or if you want to photograph the sky. On the other hand, if you want to capture the slow process of budding flowers, calculate 30 to 60 seconds. In the case of long-term projects,
The software: how a time-lapse video is born
Currently there are numerous programs (even free) thanks to which it is possible to create a video starting from the hundreds of images taken. In fact, almost all programs for cutting and editing videos are able to import, at once, all the photos taken and then turn them into a video. You can, for example, use iMovie for Mac, Adobe Premiere, Windows Movie Maker or Photoshop Lightroom (the free demo version is enough to try). Alternatively, you can make a simple image slideshow (slide show) with your standard image viewing program and then play it back at a higher speed. In this case, the minimum necessary frequency is 24 or 30 fps.
Photos with a long exposure time: Light Painting
You can also take simple photos with time-lapse effect. All you need is a camera and a light source, which will act as a “pencil” to draw on your photo. This technique is called “Light Painting”. First, set an ISO value of 100 and select a long shutter speed. Stand in front of the camera and then draw a pattern of your choice with a flashlight or any object that emits light. Again: experiment until you have found the right combination.
Time-lapse shooting offers unusual points of view and truly amazing results, with the ability to experiment endlessly. In addition to the photos that make up the video, you can make prints with the series of photos used for the movie.
