Stereoscopic photography has been gaining popularity in the social media world lately. But what exactly is stereoscopic photography? Learn more about it here, and discover 3 apps that will help you take your own stereo photos!
1. What is the principle of stereoscopic photography?
We have two eyes, but they do not see the same thing. The information captured by our eyes and processed by our brain allows us to see objects, light and depth. Cameras aren’t capable of doing that. This is where Stereoscopic photography steps in: two cameras that will represent the vision we have with our eyes. The tool commonly used is the stereoscope, a device with two eyepieces that gives the photos this dimension of depth, almost like 3D images but without the need of 3D glasses.
It consists in taking two pictures of the same subject, generally with a camera equipped with two lenses (stereo camera) placed 6 cm apart to imitate the position of human eyes, and setting the prints side by side on a steady support.
2. Stereoscopic photography, the ancestor of the 3D photos?
Nowadays, dual-camera (stereo camera) smartphones give you access to features that were previously relegated to high-end DSLR cameras. With them, you can achieve bokeh effect, wide-lens shots, and even 3D photos.On the market currently there are a lot of brands such as iPhone, Samsung, Google Pixel, Huawei, Xiaomi, that offer these features. Thanks to that, you can create the depth effect in the image when taking a picture. Some phones with a 3D screen even allows you to view a 3D image without 3D glasses.
3. Stereo 3D Cameras Vs. ToF Cameras
The principle is relatively simple: a ToF Camera captures distance instead of colors. All the pixels start counting the time at the same moment when the sensor emits light and the signal is reflected back at slightly different times.”Time of flight” (Tof) is the time that it takes for light to be projected then reflected. ToF cameras provide accurate depth-of-field data and enhance Augmented Reality experiences for 3D scanning and 3D mapping.
Although the advantageous hardware system of the latest smartphones allows you to make awesome photos, you are still able to recreate the same effect by using apps! Below let’s discover our top 3 applications for smartphones to create a stereoscopic effect or a 3D photography.
4. Top 3 of the best apps for 3D (or stereoscopic effect)
Parallax - iOS
Parallax is available on the App Store and allows users to create 3D photos from regular images Users capture the photos with the 3D Camera and then edit the 3D photos with filters and effects.
Focos - iOS, Android
Focos is both available on Google Play and App Store. With the advanced technology of machine learning, it automatically calculates the depth of field for every photo.It is also possible to add multiple lights in a 3D space, adjust the color, brightness and so on.
Fyuse - iOS, Android
Fyuse is a spatial photography app that allows users to capture space in interactive 3D images. By keeping your finger on the screen, the app saves several images and recomposes them once the capture is over.
5. How far can stereoscopic principles go?
The Spanish surrealist painter Salvador Dalí uses the stereoscopic technique to play around with the space in his drawing “Hand Drawing Back the Golden Fleece”. It’s interesting to see how far the effect can go, right?
The principle of stereoscopic vision testifies that the duality of what we perceive can be an infinite of depth.
We hope you enjoyed learning about stereoscopic photography and how close this technique is to 3D technology. We can’t wait to see what photos you will create using those apps! To push your creativity, use Pops’ 3D printing technology and see how astonishing the results can be!
