I like em. Any ideas on what he did here?

I love them. Wouldn't mind getting a print.

I guess we are the only two here who like them. I'd like a print too. Now which one..

No, I like them too, just couldn't answer your question about how they were made.

Looks like it's just a dragged shutter with multiple flash pops, camera handheld and moving.

I like them, too.

That's how one way that I've done shots like that. Though multiple exposures on film can be very similar.

I remember in the film days you had to stop down a couple of stops after every exposure?
Would this be true today you think?
Do you guys think these were done with just multiple pops at same exposure?
Nice shots. I know some guys that do the same in post but it is never like doing it for real.
Thanks for the info.

Depends on how it is done and what the background is and finally how much overlap you have of content.

I was going to suggest that it was multiple exposures. And I agree that mults should only be done for "real" with film, not with layers in PS.

If you shoot with film, underexpose, and vary the angle and distance slightly, you can actually layer up the films and get some interesting effects. Might work better with positives than negatives. Back in the early days of NDT, before the modern 3D airport-type scanners, that's how we could see through objects for real. You'd need something more powerful than Photoshop to do that with multiple digital exposures.
