Doesn't Deckard actually shift the angle the picture is taken from.....

I had always thought it was some sort of technology that could figure out what was there due to how the light reflecting off that object reflected off the visible objects on the scanned image.

I still don't know what happens in that scene, which is strange for a movie with such heavy handed exposition; even the version without narration.

GET IT - SHES A REPLICANT! SO IS HE AND HER AND HIM! OH THE OWL IS FAKE. DID I MENTION THE OWL YET? ITS FAKE!

Yet a weird 6 minute sequence with a photo editor just goes unexplained. He magically sees something we don't using technology that isn't remotely explained.

I always thought the point was that he spots a ... tattoo? Of a snake? That reminds him of the club? Or the dancer... I'm going to have to watch it again aren't I?

Yes in the 3 minute scene there were multiple indications from the picture to indicate: Chinatown (food/texts), the girls outfit (being a dancer), and an identifying tattoo. Which would point to only a few dance clubs in the city.

It was also a connection to the artificial snake scale being found in the bath tub that happened to be rare and only created by a few possible engineers. Engineers who work on robotics. One Chinatown engineer happened to be employed by the people he was looking for, who were robots in need of an engineer...

Not a far fetched connection by Hollywood's standards.

I get the point, but its not obvious how he sees things in that photo by what looks like, looking behind a door or around a corner. I guess he does some kind of perspective shift that shouldn't be possible with a plain-jane 2D photo. Maybe the idea is that futuristic cameras capture multiple angles and his tool allows him to see it?

A light field camera.
