I always love black/dark background with color contrast, so few years ago I decided to take a picture of this Cana Lily flower and edited in post to make it as dark background. I used a black poster paper as black background, the flower was outside and day was overcast so it was nice to have soft light. I edited in post to match the style I was looking for.
