Help me in my research!!

[Enangel]

Hi

I have a mixed photography/science question for you, guys.

I'm doing a little research on pipes (yes, boring!!), and what happens when they broke at high pressures.

For doing that, I have a fish-tank (about 7x3,3x3,3 feet) and in front of it I have borrowed a high-speed camera (about 1500 fps) but with little aperture.

The thing that I want to do is to take pictures of the bubbles when the pipe is broken.

The pictures must have good contrast to "measure" the bubbles and their position in the fishtank.

¿What would be the optimal lighting system for this experiment?
¿Can I use some tinture to improve the contrast of the photos?

I don't have much money, so I cannot buy expensive equipment.


Thank you guys! :hugs:

I'm going to say black background with really really bright light shining through the bottom
