The TrueVirtualTours website allows you to place spherical 360° panoramas in an equidistant projection. We take seriously the quality of the panoramas, but at the same time, we allow everyone to upload panoramas, both photographers and professionals. One of our goals is to help novice photographers improve their work by following the best practices in panoramic photography.

The functionality of surveys about the quality of panoramas is designed to help achieve the goals set for the project.

What is a spherical panorama in equidistant projection?

An example of a spherical panorama image file is in equidistant projection. Aspect ratio 2:1.

equidistant projection

Due to the fact that the spherical projection introduces specific distortions in the image (especially in the upper and lower parts), spherical panoramas are almost never shown in printed form or as a regular graphics file. The TrueVirtualTours website allows you to view spherical panoramas in equidistant projection using HTML technologies. The viewer creates an illusion of presence inside the sphere, on the inner surface of which the image of the surrounding space is “stretched”.

How to check whether the loaded panorama is a spherical panorama in equidistant projection?
1. Look at the preview of the panorama.

Check out the panorama preview. The preview should look like an example of a spherical panorama above and not like an ordinary photo. The spherical panorama will contain an image of all 360 degrees around the photographer.

2. Open panorama in 360° view mode.

Look at what a panorama looks like in a 360° view. Below are examples of images that are not panoramas in equidistant projection.

We want TrueVirtualTours to publish only 360x180 spherical panoramas, so when answering questions about the quality of panoramas, please consider the information provided here. Best regards

360° panorama's quality: articles

These criteria quibble as much as the user sees, because the tours / panoramas checked by these criteria claim to be included in the “Best” category, which means they have to undergo a rather strict quality check.

This article contains information about the rules for accessing 360° panoramas, articles, and other materials on the TrueVitrualTours website. Here you will also learn about the cost of posting panoramas on the site as well as the income that you can get by placing a 360 ° high-quality panorama

Are there any elements in your 360 ° panorama that interfere with viewings, such as logos, a tripod, a photographer (if it is not part of the panorama), a shadow or a reflection of a tripod or photographer in a panorama? If so, then this affects the quality of the panorama. Next, we consider examples of unsuccessful examples of extraneous elements in the panorama. By avoiding this you will improve your work!

There are so many different ways to create and stitch spherical panoramas. Some equipment or software does not allow to achieve high quality 360 panoramas. We want only the highest quality work available for general viewing.

If you did not find a good name for your panorama and did not add a meaningful description, this may prevent others from finding your panorama and viewing it, even if your panorama is of high quality. Consider the following tips.

360-degree panorama (virtual 3D/VR tour) is one of the types of panoramic photography.

Many novice photographers have probably seen interactive panoramas on the Internet where they can spin and see everything around them. Often such content is called 3d panoramas.

I think many people will be interested to see the list of equipment used by photographers when shooting their wonderful 360-degree panoramas. When deciding whether to purchase equipment for shooting panoramas, it will be useful for photographers to familiarize themselves also with the quality of works you can make with these 360 cameras.
