If I were to give one piece of advice, it’s to study light. Study it in everyday life. Pay attention to its properties and how it behaves. See how it changes after the sun dips below the horizon but it’s still not dark. See what it does when it bounces off a white wall, or wraps around a black sphere, or morning light shines through the hair of someone you love. Then capture it with whatever camera you have.
Light. It’s all that matters. If you’re not a student of light, you’re barely a student of photography.
And celebrate the people, places, and ideas that you love.
