Inner Space Meets Outer Space
When I last visited the Monterey Bay Aquarium in Monterey, Califronia, my primary interest was jellyfish. I wanted to create the effect of an image you might see in astrophotography similar to photographs of deep space nebulae. I waited for this jellyfish to move into good light.
By making adjustments to the camera settings, the jellyfish remained well-lit while the area surrounding the jellyfish darkened. The particles floating within the tank took on the appearance of "stars" and the lovely patch of blue is due to the color of a wall within the display.
