No photo-manipulation. Explanation as follows:

Cold water, red and a little orange food coloring, ice, long shutter, high aperature, tripod, tiny waterproff flashlight in the back of the tub, little bit of light peeking in from the room behind, and that's it.

The "blood" and water colors were expected. The texture on the tile and porcelain was a result of the digital noise (b/c of dark), shutter and aperature. I can't explain the steel nozzle and handles (my only guess is that due to the lack of light, my camera tried to compensate for it by coloring in the shapes it captured). Those came out with a pure black and white, almost cartoonish look.

The extent of the changes on that were resizing it from 2274.

Enjoy.

(UPDATE: Since everybody keeps asking, the food coloring did not stain anything, it just washed right down.)
