Thank you oldmacman. Just a few comments and questions to your reply.
The reason the camera isn't aimed at the faucet over one of the sinks is because I mainly wanted to get a good shot of the water splashing and spreading out from said splash
What would be good to use as colorful makeshift backdrops?
Yes, I do need to figure out how to use the manual focus on it. I will be reading up on that in the manual (im going slow with all this as to not overwhelm myself and keep it fun).
I don't have any off camera flash. The only thing I can think of would be to use a flashlight?
I find the best way to learn is by trying and getting feedback. So hopefully my comments were helpful. If you want some varying water, try dividing the stream before it makes it into the camera frame. I have used a chip back in the past with great results. It's good because the bag doesn't break down with exposure to water and with a shallow DOF, you can't really tell what it is. I even had it refract a word into one the of the drops. I'll see if I can find that shot.
A flashlight won't throw much light. You'll be happier with the results from your on camera flash. Try the flashlight, though. You might get some interesting effects.
