At home we have a Christmas cactus, and I thought it was just a regular cactus, except this one is not loaded with a gazillion thorns. To my amazement, it recently began to flower. At first it was just a little pink, but it continued to grow for the next few days, leading to the image captured above.
The following are the settings I used to make this image:
Camera: Nikon D200
Focal Length: 135 mm
ISO Speed: 200
I used a simple black background to give better contrast to the pink flower. Lighting was available light pouring in thru my west-facing windows.
