I used to do shoots like this standing on bedside tables but these days I can barely stand at all so I put the camera on a boom stand positioned directly over the model whether it be on a bed or in a bath. The boom stand is quite big and heavy so sadly I can no longer really do these shoots interstate anymore, which is depressing because I really love the top down aesthetic and the looks you can achieve.
With this shoot I was using Adobe Lightroom's tethered feature running a 3 meter TetherTools cable up to the camera to shoot remotely.
