Take multiple pictures and merge them
To turn your pano painting into a VR image, you can take multiple pictures and merge them into a single 360-degree image. This process is called stitching and is an integral part of creating an immersive VR experience. Here's a step-by-step guide on how to do it:
Step 1: Taking the Pictures
Take a lot of pictures covering a full 360 degrees on the horizon and also capture the zenith point (directly above you) and the nadir point (directly below you). Ensure there is some overlap between the images, as this will make it easier to stitch them together. Try to keep the camera position consistent between shots, especially if you have objects at various distances, as changes in position can create alignment issues.
Step 2: Choosing a Stitching Software
Several stitching software options are available, such as H. Dersch's Panorama Tools, Andrew Mihal's Enblend and Enfuse tools, or free programs like Stereo Photo Maker. Some 360 cameras also have built-in stitching capabilities, which can save you time and effort.
Step 3: Identifying Control Points (CPs)
Control points are identical details in different images that the software uses to overlap and merge the photos. The more overlap between sequential images, the more CPs you will have. While the number of CPs is not as crucial as their quality, having more CPs can help improve the precision of the final image.
Step 4: Merging the Pictures
Use your chosen stitching software to merge the pictures into a single image. An equirectangular image is twice as wide as it is high, and this projection type is commonly used in VR to display a sphere on a plane. Ensure that your software correctly aligns the images, especially if you have a clear horizon or vertical line in the scene.
Step 5: Adding Metadata (Optional)
If you want to display your VR image on specific platforms or websites, you may need to add the required metadata to your 360-panoramic shot. This metadata allows platforms to recognize and display your image as a VR experience correctly. There are desktop apps and services like Facebook and Google Street View that can help you add this metadata.
By following these steps, you should be able to successfully turn your pano painting into a VR image by taking multiple pictures and merging them. Remember that practice makes perfect, and don't be afraid to experiment with different software and techniques to find what works best for you.

Edit the metadata of the image
Editing the metadata of an image or video is essential to ensure that VR players can correctly interpret and display your pano painting in virtual reality. Metadata provides instructions to the video player on how to handle the file, especially important for VR as it involves footage from two lenses.
There are various software tools available to edit and add metadata to your VR images and videos. Adobe Premiere Pro, for example, allows you to manually define the output layout, horizontal and vertical Field of View (FOV), and edit the disparity adjustment. You can also use the Stretch to Fill Scaling setting under Export Settings to optimise your VR exports.
If you are using Blender, you can set metadata tags using ffmpeg or a script. You can install exiftool, available on most Linux distributions, and run a specific command to add the proper tag for 360-degree video recognition.
For Oculus 360 photos, you can display your metadata by downloading and installing the Oculus Mobile SDK. You can then run the SDK-360Photos app to access your tags.
Additionally, there are online tools such as Spatial Media Metadata Injector, YouTube VR Metadata Tool, and Facebook 360 Video Metadata Tool, which can help you add the necessary metadata to your VR content before uploading it to platforms like YouTube VR, Facebook 360, or Oculus Video.
It is important to note that some VR players may have specific requirements for metadata, so ensure that you are familiar with the platform you intend to use for your pano painting in VR.

Use a desktop app to add metadata
To turn your pano painting into a VR image, you will need to add metadata to your image file. This can be done using a desktop app.
Metadata is "data about data". It is a set of information about a file's source, author, and other details. For images, metadata can include copyright notices, author information, dates, locations, and descriptions.
Adding metadata to your pano painting will help protect your digital image from being misused or misrepresented. It will also make it easier for your image to be searched for and located on the web. Additionally, metadata can provide important descriptive information about your image, such as its caption, title, author, how the image was made, and legal information.
Using a desktop app to add metadata:
You can use a desktop app, such as Adobe Photoshop, Adobe Lightroom, or ExifToolGUI, to add metadata to your pano image. Here are the general steps to follow:
- Open the image file in the desktop app.
- Locate the metadata panel or section within the app. This may be called "Properties" or "Info".
- Edit or add the relevant metadata fields. This may include fields such as title, description, origin, author, copyright information, and location.
- Save your changes.
Specific instructions for ExifToolGUI:
If you are using ExifToolGUI, follow these steps:
- Install the latest version of ExifTool by Phil Harvey for your operating system.
- Open the file with ExifToolGUI (Menu>Program>Workspace definition file>Load...).
- Open the Metadata panel and the Workspace.
- Add the relevant metadata. For a photo sphere, you may need to add parameters such as ProjectionType="equirectangular", UsePanoramaViewer="True", and details about the image width and height.
- Save your changes.
Remember that adding detailed metadata will ensure your pano painting can be properly viewed and searched for as a VR image.

Use a telephoto lens for gigapixel panorama
Creating a VR image from a panorama painting involves several steps, including capturing or stitching together multiple images, adding metadata, and using specific software or apps to create a 360-degree VR experience.
One approach to capturing panoramic images is by using a telephoto lens to create a gigapixel panorama. Here are some detailed instructions and considerations for using a telephoto lens for this purpose:
Choose the Right Lens
Select a telephoto lens with a focal length of 400mm or more for optimal results. Longer focal lengths provide greater magnification and allow for extreme magnification of distant objects. Additionally, consider using a macro lens alongside the telephoto lens to experiment with different effects and projects.
Camera Requirements
Ensure your camera has a high megapixel count and image stabilization. The combination of a high-resolution camera and quality optics will play a significant role in achieving a sharp final image, especially in low-light conditions.
Optimal Weather Conditions
Clear weather with minimal wind and atmospheric turbulence is crucial for successful gigapixel panoramas. Atmospheric turbulences and heat haze can negatively impact the clarity and sharpness of your images.
Shooting Technique
Capture a large number of photos, covering the full 360 degrees on the horizon and including the zenith (up) and nadir (down) points. This will provide ample overlap and control points (CPs) for stitching the images together. Control points are identical details in different images that software uses to overlap and merge the photos.
Stitching Software
Use stitching software, such as PTGui or Photoshop, to merge your images into a single, high-resolution panorama. The software will align the images based on control points and create a seamless final image.
Post-Processing
Post-processing is an essential step to refine your gigapixel panorama. Use software to correct any stitching errors and remove parallax issues that may occur during the stitching process. Enhance the overall quality of the image through adjustments and corrections.
By following these steps and considerations, you can effectively use a telephoto lens to create impressive gigapixel panoramas that serve as a foundation for creating immersive VR experiences.
