This is a setup from the swedish photographer Carl Magnus Swahn.
– I used a small aquarium filled with water, and then I simply dropped different fruits in it. I dropped the fruit with one hand and triggered the camera via remote with my other hand. It took a while to get the timing right. Between every shot there was water drops on the inside of the aquarium, so I had to wipe it before the next shot to avoid blur.
These photos are from a series of about twenty different fruits dropped in water. So there was a lot of wiping the window of the aquarium. And a lot of retakes when the timing wasn’t perfect.
If I had to do it again today, I would probably done much more in the post editing. Even for those photos I reused parts of the best splashes. The most resonable way of doing this could be taking separat photos of just the water splash and the surface, and then edit in the fruits. Then I would be able to photo all fruits from perfect angles and combine it with perfect photos of splashing water.
I used two Canon EX 550 for this shot. They burn pretty fast, so the water splash can freeze. I had one with a soft box behind the aquarium and one without modifier from the right side. On the opposite side I used a reflector. I shot many different fruits and there was many different strobe settings depending on if the fruits were light, dark, colorful etc.
