Pictures with water is very similar to bodyscape photography with little add-on called water. You can spray water on your model or pour water on.
You want your light to be behind your model to make water stand out. Water has lot of shapes and reflections in it, so placing the light correctly is very important.
IMPORTANT: put the light behind the model and point it on her.
How to pour water when you are in studio?
Get a small plastic bath where your models can stand in.
Also get some plastic cover to put under the bath so if there is any excess water, it wont soak in your studio floor.
You can spay water or just pour water from cup.
Get your self proper hi sync flash remote. This way you can put your shutter time really high. As high as possible.
Pro tip:
- Use oil to get body nice and shiny and so water would fall of better
- use hi sync remote for your flashes, to get fast shutter speed.
- also use very strong flashes and always put your flash on max strength. Without High-Speed Sync you cant use that.
- put your flashes behind your model
