You may have a model on hire for your photoshoot.
And they might not want to hang around all day.
So one solution is to take that model, place them in a studio and take the shot.
Then...
...The photographer can find a suitable background and drop it in behind.
This is quite a technical skillset.
In this recent example, our client wanted a shot of a skylight, but the skylight was in the studio...
So we took the studio shot and added the roof and background.
