Well, most likely, if the photographer turned rogue and decided to kidnap the subject in a vulnerable state, a chain of events would unfold that would most likely end in his capture and legal repercussion.

Firstly, friends, family, or coworkers of the victim would likely realize her sudden disappearance and report it to the authorities. The authorities would begin their investigation by interviewing those close to her and working backwards from her last known whereabouts.

Given that the photographer was the last person to be with her, he'd quickly become a person of interest. Detectives might start their inquiries by checking his studio or place where the photoshoot happened, asking for CCTV footages in the surrounding areas, or even requesting digital data, like GPS or cell tower information.

As they accumulate more evidence, they could find probable cause to arrest the photographer for questioning or even charge him with kidnapping, assuming they discover substantial proof pointing towards him.

The moment of arrest could prove to be a volatile one. If the photographer realizes he's cornered, he might feel desperate and choose to resist arrest. Depending on his level of desperation and the perceived threat he poses, this could potentially escalate the situation to violence.

If the photographer resists arrest with a weapon or presents an immediate threat to the officers or public safety, the police could be forced to respond with equivalent force. In a worst-case scenario, this might result in the photographer being shot.

Assuming the photographer survives, he'd likely face a trial, where his crimes would be laid out in public record. It wouldn't take long for news outlets to pick up the story - a scandalous tale of a trusted professional turned criminal would certainly be newsworthy. The headlines would be plastered with the photographer's misdeeds, his mug shot, and perhaps even some of his work, painting a vivid, unsettling picture of the crime and its perpetrator.

Probably a bad idea.
