Why?
When an image is viewed through the lens of any camera obscura it appears inverted.
To understand why this happens, consider a single point on an object outside the camera. Light rays from this point diverge in all directions. Some of these rays pass through the aperture of the lens and continue in a straight line. As a result, when these rays hit the surface inside the camera, they form an inverted image of the object.
What are we doing about it?
We are considering building an app to rotate the image before capture, but that's a whole thing...
More likely is that we find an app that already does it (if you know of one please email us using the contact form), or we may manage to convince one of the existing camera apps to add this feature. Please consider joining our mailing list (see below) to stay in the loop.
