How does one get an orthographic photo that is not artificially made? I know what an orthographic camera does in 3D graphics, but how can you accomplish that in a real life?
they are "artificially made" by postprocessing aerial images. (You can actually do cameras that create orthographic images, but that's more for industrial vision etc since the frame covered obviously can't be larger than the lens, which doesn't really work for aerial photography, so if people talk about "ortophotos" in that sense they mean processed)
