As technology develops, we can hear new concepts every day, like 3D photography, 360-degree photos, and more. According to our recent research, only a few people are aware of these new concepts related to photography, not to mention how to make such photos. So, we are going to talk about what is the 3D image in detail below. If you are already bored of taking simple pictures and looking for new challenges, you will find our article helpful. Moreover, we will show you all knowledge about 3D images to help you shoot and create them easily.
3D photography, also called stereoscopic photography, is a new art of photography, which creates three-dimensional photos by displaying two slightly offset photographs.
Stereopsis is the principle that the 3D effect works. We all have two eyes. And each of them is in a different location. So each eye could see a slightly different image. The difference between these pictures lets you perceive depth and the 3D photo. Taking two images of the same subject offset by the same distance creates a three-dimension effect.
3D photo is about how you take the pictures and look at them. The way to view a three-dimension photo is different from ordinary images. If you want to see the three-dimension effect, you have to look at the two pictures with each eye. Then your brain will overlap the two pictures together and perceive a single three-dimensional image.
In a word, both the ways to take 3D photos and see three-dimensional photos are different from ordinary photos.
Before learning how to make a 3D photo, you should understand how to display and view 3D images. You can view a stereoscopic 3D picture in different ways.
1. View 3D photos with 3D glasses. If you have watched 3D movies, you know 3D glasses. You can see overlapped images but not a 3D effect with it. Like 3D movies, you can use 3D glasses to see the appropriate view. There are various 3D glasses, like color filtering glasses, polarized glasses, and active shutter 3D glasses.
2. View a 3D photo cross-eyed. It is the simplest way to view the 3D effect without extra tools. The two pictures are side by side on the right view placed on the left side while one is on the right side. Then put the pictures in the right front and cross your eyes to overlap them.
3. See 3D photos parallel. Like cross-eyed, you need to put the two images side by side. But to produce a single 3D image, you have to use a stereoscope.
4. Display 3D pictures by mirror split. This way also overlaps two images together to create a single 3D image, but it uses the reflection principle to achieve such an effect.
As I said, if you want to create a 3D photo effect, you have to take two images of your subject. And there are several steps you can follow.
Step 1: Decide a subject
There are many subjects worth our attention, beautiful flowers, famous buildings, car models, people and so on in our life. In short, you have to focus on one subject and capture the details, but not macro shots.
Tip: Do not put your subject in front of a flat background, like a wall.
Step 2: Take two photos of the same subject
Place your camera 10 to 15 feet away from the subject. Take the first shot. And then move your camera over slightly left or right and take the other. Do not shoot the thing in two different scenes. Otherwise, the creating of a 3D photo is impossible. We suggest changing 1/30th – 1/50th the distance when you take the second picture.
Step 3: Edit the images in 3D
Then you can use a photo editor to convert two 2D images into a single 3D photo or put them side-by-side. When coming to how to make a three-dimension effect, it depends on what method to view the 3D image you want to use.
When iPhone 7 was released, Apple integrated 3D technology into iOS. And Google has a built-in 3D photo feature into the latest versions of Android. That means you can create and view a three-dimension effect without digital cameras. If you search for a 3D photo in App Store or Play Store, you will get a long list. And to help you learn about how to make a 3D photo on a smartphone, we use the 3D Camera app as an example, which is available to iPhone and Android.
Step 1: Install and open the 3D Camera app and focus on the subject you want to capture.
Step 2: Tap on the camera icon to take two side-by-side photos for making a 3D photo effect.
Step 3: After shooting, you can view the result in three modes, Color Anaglyph, Gray Anaglyph, and Stereogram.
Step 4: Tap on the Share icon on top of the screen. Then you can decide to export the result to Camera Roll or Photo Gallery. It also supports sharing your works on social media, like Facebook and Twitter.
Even if you use some 3D vision photo viewer device, you also need some photo viewer for your computer instead. WidsMob Viewer Pro should be the program you need to try. It is a versatile program to view, edit, and manage photos within Mac with ease.
In this article, we have talked about 3D photos. And now you might grasp all the necessary knowledge about this new type of photograph. We see our world with two eyes. And they tell us the depth of a scene is the principle of 3D photos. When a camera captures a picture, it changes our three-dimensional world into a flat plane and destroys any depth the original scene had. Making a 3D photo is to reconstruct the scene depth. And we share multiple ways to view 3D effects through 2D images, like 3D glasses, cross-eyed, parallel, and mirror split. These ways determine how to create 3D images partly.
