Basically I got a empty glass bottle, tied it upside down to my background stand over a bucket and photographed the coloured water coming out. I tried different colours but I liked blue the best as it's slightly see through compared to the other food colouring I bought.
Settings and equipment were as follows: Nikon D800 with 105mm Micro VR lens. 1/250th of a second at f/22, ISO 100. Camera was tripod-mounted and I used a cable release for the shutter having focused the lens previously and knocking it back to Manual focus. Regular food dye, a bucket, a background stand, a measuring jug (to decant the coloured water into the glass bottle), a glass bottle and a towel. Oh, and 2 Interfit EX150 heads on full power. One was pointing at a white background and the other was in a softbox pointing straight at the bottle.
These are the results:
I decided to make a triptych (more of a quadtych!?) out of these pictures which I am going to frame and put up in our kitchen, I'm that chuffed with it :)
