What did you use as light source? continuous spectrum tungsten, or spectral fluorescent/LED?

Any saturation adjustments in PP?

Thanks guys!
Very tedious process to say the least. From the moment I prepared the concoction until I found the angle at which I saw the ripples, focusing on them it's a long process. Couple of pictures and the film on the loop is gone.
Rinse and repeat. Many times. Still a work in progress.
As for the light, one LED fixture hanging from the ceiling, one LED panel on a side on a tripod and one reflector to the other side.
Shoot RAW, a bit of a contrast added in PP.
