what is stereoscopy

"Stereoscopy" sounds like something new and challenging to many laymen and even to some photographers. But it's a simple concept that's been around for quite a few years now. It is commonly known as 3D photography. It is based on a theory formulated by Charles Wheatstone back in the 1830s when he invented and created the stereoscope. According to Wheatstone, it is possible to obtain a three-dimensional image by combining two-dimensional images, especially when they are taken or drawn from two different points. To prove his theory, he used mirrors, showing one image to his right eye and the other to his left. This allowed each eye to see the images separately and produced the 3D effect itself. Wheatstone created the stereoscopic viewer and provided an interesting way for people to watch or observe images.

What Is Stereoscopy?

Stereoscopy is like a magical window to 3D worlds, even before 3D movies existed. It lets you see 3D images using a special tool called a stereoscope. This wasn't just for fun; it had educational and artistic uses too!

Stereoscope and Photography

In the early days of photography, a process called daguerreotype was used. It was the first type of photography. People linked it with the stereoscope. This led to the creation of the stereoscopic camera, which had two lenses placed at different distances, just like our eyes. Later, David Brewster made it even better by replacing mirrors with lenses. This device became very popular and played a big role in making photography popular.

How Does Stereoscopy Work?

Stereoscopy is not as complicated as it sounds. It's all about looking at 2D drawings, prints, or photos with both eyes at once, making them look 3D. You can think of it like covering one eye while looking at something and then quickly switching to the other eye. It seems like the object has moved a bit. Basically, you're seeing one object in two or three dimensions. In stereoscopy, pictures are placed side by side at a certain distance. When you look at these images through a special viewer called a stereoscope, they merge into a single 3D image.

One famous example of a stereoscope is the View-Master, a toy from the 1920s. It used cards that looked like slides. When you looked through the viewer, it felt like you were right there in history.

Why Is Stereoscopy Important in Photography?

Photography has always been about capturing things in 3D and 2D. Stereoscopy is part of photography, even if some old-school photographers disagree. Creativity is the main reason to explore stereoscopy. When you tell a story, you want to do it in the best way possible, right? 3D images can help you achieve this. They have more depth, life, and can grab your audience's attention. 3D photos challenge your creativity because they look like real life.

Some people say turning regular photos into 3D is like copying nature, which isn't the point of photography. They think photos should show nature in unique ways, through the photographer's eyes and camera lens. But 3D photos are still similar to regular ones, with a special twist that makes them feel closer to real life.

Applications of Stereoscopy

Another reason to try stereoscopy is that it's popular. As a photographer, you'll notice that some people really like 3D images. It's almost like they can reach out and touch what's in the pictures! Just thinking about it can have a ripple effect. Lastly, adding stereoscopy to your portfolio is a smart move, especially in our tech-savvy world. While finding a stereoscope might be tricky nowadays, it doesn't mean you can't use stereoscopy in your work. There are many techniques to make your images look fascinating.
