Thats a cool idea. Did you just have a bowl of regular water and dropped food coloring into it or something? I would end up wasting an entire bottle if I tried that.Really neat idea tho and something different.
I'm a newbie, and I've tried photographing water droplets, but I had the same problem as sftempest66, I couldn't get the tip of the droplet to be sharp. I've tried everything, changing shutter speed, changing aperture, focusing on different places... What was I doing wrong?
