The train is the product
A flying dress is an ordinary bodice attached to an extraordinary amount of fabric. The part you wear is close-fitting and unremarkable. The part that makes the photograph is the train behind it, metres of light synthetic cloth cut wide and hemmed to be thrown rather than worn.
That is worth understanding before you choose anything else, because it explains the whole shape of the session. You are not being photographed in a dress. You are being photographed in the middle of a piece of fabric that somebody else is operating, and the two of you are working together on a timing problem.
Someone throws it. That someone is on the payroll
Every one of the three photoshoots includes an assistant whose entire job is the dress. Not a second photographer, not a guide. One person holding the train, lifting it, throwing it on the photographer's count, and getting it off the ground between frames.
This is the single most common thing people do not expect, and it is the reason the pictures look the way they do. Left alone, a train of this size lies on the floor. A soft breeze lifts the edge of it and nothing else. The arc you have seen in other people's photographs is a throw, caught at the top of its travel, usually within about a fifth of a second of leaving the assistant's hands.
It also means you are never wrangling your own dress. You hold a pose, you look where you are asked to look, and the fabric is someone else's problem. People consistently relax once they realise this, and relaxed is most of what a good frame needs.
What the wind does, and what it does not
Wind helps and cannot be relied on. A steady breeze across a rooftop will hold a thrown train open for an extra half second, which is a long time at these shutter speeds and produces the frames that look effortless. On a still morning the same shot is purely a throw, and it still works. It is simply tighter timing and more of them.
Strong wind is the harder case. Past a certain point the fabric stops forming a shape and starts behaving like a sail: it wraps, it covers your face, it pulls. A photographer who has done this before will turn you so the air is coming across rather than at you, and will shoot the half-second after the gust rather than during it.
What none of this involves is standing still waiting for weather. The session is built to produce the photograph on a calm day and to take the gift when the air cooperates.
Why thirty to forty-five minutes is the right length
Each of the three photoshoots is a thirty to forty-five minute shoot, and people occasionally read that as short. It is not a cost decision, it is a physical one.
Throwing a five-metre train is work. The assistant does it dozens of times, and so, in a quieter way, do you: holding an extended pose repeatedly, often with your arms up, usually on an uneven surface, in a garment with real weight to it. The frames from the first twenty-five minutes are, reliably, the ones you choose. After that the throws lose height, the poses stiffen, and the fabric picks up dust that then has to be edited out.
Forty-five minutes of this produces well over a hundred usable frames. That is what gets colour-graded and delivered, and it is why the inclusion is written as a number of photographs rather than a number of hours.
What to do with this on the day
Three small things make a measurable difference, and all three are about cooperating with the throw rather than the camera.
- Hold the pose through the throw, not during it. The fabric takes a beat to open. Most of the frames people lose are lost by relaxing early.
- Keep your weight on the back foot. It lets the photographer find a line between you and the horizon, and it stops the train pulling you off balance.
- Tell the assistant if the dress is pulling. They can change which side they throw from. Nobody can see that from behind you.
