Water Drop Splash
Would you believe if I say this was taken in direct afternoon sunlight?
With a circular metal container and high shutter speed, the background gets dark (even in bright sunlight) and the container reflects all the light on the drop.
The first pic (with 3 drops) was my first successful waterdrop pic back in 2014.
It's a candle in the background.
I lit a big fire in the background and the rest is a glass with water.
