How to Make 3D Pictures: Effective Tutorial | Tips

Creating captivating 3D pictures is a rewarding creative endeavour. But how can you make your images truly stand out? In this article, we will discuss how to shoot 3D pictures with your camera, create 3D pictures in Photoshop, and offer pro tips for taking stunning 3D pictures.

How to Shoot 3D Pictures With Camera

The Rocking Method

The rocking method is a beginner-friendly approach that can even be used with phone cameras. This method works best for stationary subjects.

To begin, take the first shot while supporting your body on one foot and leaning slightly in that direction. Then, for the second shot, switch to supporting your body with the other foot and lean in that direction.

This slight shift in position captures two perspectives of the subject, mimicking the depth our eyes perceive. Later, use software to merge these images, creating a 3D effect.

The Tripod Method

Like the rocking method, the tripod method involves taking two images, but this time you use a tripod to keep the camera stable. The tripod is also useful when you require additional lighting.

For the first shot, place the subject at the centre of the frame. Then, move the tripod with the camera either to the left or right, ensuring the distance between the first and second positions is greater than two inches. Recenter the subject for the second shot and consider altering the angle of the subject slightly to maintain the same framing.

Finally, merge the two images using photo editing software to achieve a captivating 3D effect.

Make Your Own Mirror Splitter

Creating your own mirror splitter for shooting 3D pictures is a more intricate process that involves some do-it-yourself expertise. To start, gather four mirrors—two small and two larger ones.

The purpose of the smaller mirrors is to split the frame into two parts: one for the left-eye view and the other for the right-eye view. You can direct each perspective to its respective side by skillfully positioning the small mirrors.

The larger mirrors come into play as they reflect these split views onto the subject. As a result, you will obtain two distinct images capturing different perspectives. You then combine the two images using a photo editing software to create a 3D photo.

How to Make 3D Pictures in Photoshop

Step 1: Open Stereo Pair Photos in Adobe Photoshop

Begin by launching Adobe Photoshop and opening a stereo pair of images. These images are captured using two cameras at a fixed distance or a single camera shifted sideways on a tripod.

You can use pre-made stereo pairs from sources like Shutterstock or capture your own by taking two slightly offset photos.

Step 2: Activate Snap Alignment

If the stereo pair images are merged into a single file, enable the snap feature from the view menu. This will help you accurately place a guide at the centre of the composition.

Step 3: Select the First Image With the Marquee Tool

Use the Marquee tool to select the first image, then press CMD (or CTRL on Windows) and X to cut the selection. Utilize the Crop tool to trim the canvas to the desired size, focusing on the main subject.

Step 4: Layer the Images

Press CMD and then V to paste the second image on top of the first. This superimposition lets you visually discern the angle difference between the two shots. Toggle the layers on and off to observe this effect.

Step 5: Rename the Layers

Clearly label the layers as "Left" and "Right" to distinguish between the images.

Step 6: Convert to 3D Anaglyph

Double-click the "Left" layer, uncheck the red channel and click okay. Similarly, for the "Right" layer, disable the green and blue channels. This step transforms the image into a 3D anaglyph.

Step 7: Wear 3D Glasses

Put on your 3D glasses to immediately witness the image's 3D effect. This visual aid enables you to make subtle adjustments, rectify any double vision, and shift the focal point as needed.

Step 8: Disable Snap

Turn off the "Snap" feature under the View menu for finer control. Press CMD/CTRL + T to transform the image, then move it horizontally to find the spot where a certain part of the two images aligns perfectly.

Step 9: Crop the Aligned Image

Once alignment is achieved, you might notice a strip along the edge where the images overlap. Use cropping tools to eliminate this strip, resulting in a polished and aligned 3D image.

Pro Tips for Taking 3D Pictures

1. Choose a Subject with Depth

Select subjects that have noticeable depth and dimension, as this will enhance the 3D effect. Scenes with foreground, middle ground, and background elements create a more immersive and captivating experience.

2. Shoot at Low Light Level

Lower light conditions can help create more pronounced shadows, contributing to the perception of depth in your 3D pictures. Consider shooting during the golden hour or in dimly lit environments for dramatic results.

3. Use a Remote Trigger

To avoid a camera shake, use a remote trigger or a timer delay when capturing 3D pictures. This ensures the camera remains stable during the exposure, resulting in sharper images and a smoother 3D effect.

4. Use a Wide-angle Lens

Utilize a wide-angle lens to capture a broad field of view. This will allow you to create stunning panoramic 3D pictures, encompassing more of the scene and giving viewers a greater sense of immersion in the image.

5. Never Take a Horizontal Photo

To avoid a flat-looking 3D photo, shoot vertically instead of horizontally. Adopting the portrait style allows you to capture more depth in the scene, emphasizing the subject's height and creating a more realistic 3D effect.

6. Take Multiple Images

Creating a 3D image requires multiple photos of the same subject from slightly different angles. This will provide more options during post-processing and increase the likelihood of capturing the perfect 3D shot.

7. Capture Images from Left to Right

When shooting multiple images for a 3D effect, start from the left side of the scene and gradually move to the right. This approach ensures smoother transitions between the images, resulting in a more cohesive and realistic 3D picture.

8. Avoid Recording Sudden 3D Depth Changes

Sudden 3D depth changes in pictures occur when there is a rapid shift in the distance between foreground and background objects. These abrupt changes can result in subpar 3D images that may appear jarring and uncomfortable.

To maintain high-quality 3D visuals, ensure that objects closer to the camera exhibit minimal movement compared to those in the background. This will create a smooth and natural transition between frames.

9. Try Different Settings in the Editor

Experiment with various settings in the post-processing editor to enhance the 3D effect. Adjusting parameters like depth of field, convergence point, and parallax can significantly impact the final image. Take the time to explore different configurations and find the one that best complements your subject, adding depth and dimensionality to your 3D pictures.

10. Use Natural Perspective

Achieving a natural perspective is vital when capturing 3D images. Aim to replicate how the human eye perceives scenes, avoiding extreme angles or forced perspectives that can cause distortions. Position the camera at a comfortable eye level and ensure a harmonious balance between foreground and background elements.

Conclusion

Creating captivating 3D pictures requires a blend of shooting techniques and Photoshop skills. From the Rocking and Tripod methods to using a Mirror Splitter, there are various approaches to experiment with. By integrating these shooting techniques with post-processing in Photoshop, you can breathe life into your 3D images.
