I went to a really unique old saloon to eat and took pictures. One of the pictures was blank except a strange green bright cube floating largely right in the middle of it. Apparently the camera must of picked up some kind of hologram that wasn’t visible to the naked eye. I have that picture still and it’s pretty cool.
Sounds pretty cool.
I am a hobbyist photographer, I’ll have to see if I can find a hologram somewhere and try to reproduce your effect.
Was it film or digital?
