So I was watching you tube a few weeks ago, and got lots of ideas for studio photo shoots. Yesterday I decided to try out the first one, its a simple shoot with one light.
Place the glass in front of the light source, pour in some water, colour it if you want, and set the camera on burst shoot.
pour the water and fire away.
One thing you can guarantee, no two images will be the same.
go one give it a go.
