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)
