WOW
What a fantastic set. Can you please share what did you use on pic 4. and 5? Is that flour and milk?
Thanks for your nice comment.
On picture 4, you're right, it's flour. On picture 5, it's water. But i use a white sheet of paper which i sticked on the source of light to smoothen and diffuse it. That white paper reflects on the water, thus it looks like milk.
