For those into photography, the camera used was an Pentax EI-200 (Digital). Exposure Time: 1/100th second, Aperture: f/4. Subject distance was approximately 3 inches.
Bacopa monnieri flower.
This is an artistic photo taken of a Bacopa monnieri flower that grew up out of my 75g tank.
While this isn't an illustration, this is one of series of photos that I took as a work of art, rather than as documentation of a plant or a tank.
The photo was not altered, the purple coloration is from the tank lighting reflecting off the water surface, and the blurring is created by careful use of depth-of-field. This is one of the few digital photos I've taken that has demonstrated tight depth of field.
