As I descend into dark waters, my blue flashlights reveal a spectacular display of fluorescent colors shining out from some of the corals and marine creatures below. Normally hard to detect with the naked eye, this secret, colorful light show gleams as brightly as an ’80s disco within the beam of my lights.
Fluorescence on the reef occurs as shorter wavelength blue light is absorbed by special proteins in tissues and is reemitted as longer wavelength greens, reds, oranges and yellows. While the ocean naturally filters light, leaving the underwater world cast predominantly in blue below 15 meters or so, the addition of concentrated blue light from the flashlights and flashguns attached to my camera rig stimulates the strongest response from the fluorescing proteins. Yellow filters on my lenses and dive mask block the stimulating blue light, enabling me to see and capture the full extent of the psychedelic spectacle.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
