Old images on glass – daguerreotypes and ambrotypes are like ghosts in that they vanish into thin air then come back again. The directness of the first portraits from the 1840’s & 50’s brings them to life unlike later paper or tin images.
These images are like early holograms – more 3D than 2.
Like ghosts they are difficult to capture with a modern camera or even with the naked eye.
And unlike with paper these glass images captured a little piece of soul to say hello to the generations to come and say rather elegantly “we were here.”
