Great.
Thank you for sharing this with us. I generally find the word “moment” more helpful than “mood”. I feel like “mood” is part of a moment. Photography, like film, is a visual story telling medium. Within a “moment” a Photographer or Director of Photography needs to consider many things which make up a moment.
Color
Atmosphere
Tonal qualities
Design
Texture
Wardrobe
Makeup
Background
Lighting
Lens choice
Framing
Movement
Mood
Story
Etc
It’s all of these things together which come together to create a “moment”. That’s how I see it anyway. It helps me deconstruct my thought process and other photographers work as well.
Best of luck continuing with the course!
