How To Achieve This Popular Style?

I know this style has been around for decades, but it's recently shown it's popularity again, particular in editorial work. Very much emulates the look of polaroids, but slightly more controlled and tamed, per se.

Here's just one of millions of examples:

I love the filmy, almost cross-processed look, but I feel like I can pull that off tinkering around in PS a bit. What I want to know is what the in-camera techniques are. Obviously the f/stop is very small as the images are quite sharp and there doesn't seem to be much ambient light. The flash has to be very close to the lens, but even using a 580EXII on camera, the shadow still seems to be too far from the subject. Simply intelligent use of the pop-up flash, maybe? I've even held my 580 alongside my lens using a TTL cable, and once mounted the flash upside down on the bracket to negate the concept of using a flash bracket to keep the flash high above the lens, but instead to keep it as close as possible.

Is there a common practice to getting such a style of photograph?

I feel so dumbfounded, as I've been doing this for many years and I pride myself on understanding the inner workings of portraiture and wedding photography. I've spent so much time learning how to make the most of my off-camera lighting that I've forgotten how to get that 'disposable camera' look that seemingly every new photographer possesses in his early days.

Thanks so much...

if I had to guess, it wouldn't be use of a flash, but some type of warmer constant light source.

Plus, the 'film' effect is easily created in LR2 when you use the 'zeroed' preset and adjusting the levels.

I think https://photography-on-the.net/forum/member.p​hp?u=169185 has a similar style to what you are looking for and has described how he does it.

Harsh shadows are caused by undiffused light, if you look at the angle of the shadow you can usually tell where it's coming from.

Often times a ringflash will give you that halo-shadow look.

But in the fashion screen from vogue, the shadows are very diffused.
Not sure but I think if you wrote an honest and to the point e-mail to the photographer, Camilla Akrans, that you respect her style and work and want to know a bit more about her process...you'd have an exact answer.

Looking deeper into her work; whoa. There's more to her work than a processing style and lighting, that's for sure.
