I teach about finding subjects to shoot that have character. A subject that is unique and different from all the others in that species of plant or flower.
When you find that special character be sure to shoot many different compositions because that subject will only exist for a short time, and you will never be able to reshoot it again.
I found this character of a tulip at the flower department of a grocery store. I loved how the one petal dropped down and was supported by the green leaf. It was unique and different from the hundreds of other tulips in these pots.
I bought the pot, brought it home and set it up with a green printed background and photographed it as a horizontal composition. Used the natural room light, but the small spotlight was added in post processing.
As I said that when you find a subject with character make sure you shoot different composition, because this flower is in some landfill rotted away, so you can never reshoot it. I shot a few horizontals and then shot some verticals, and this was my favorite vertical.
I also like to watch the flower as it goes through its life cycle and shoot again as it starts to wither and die. As it dies the petals will reshape into artistic designs, so don't miss out on that opportunity for some great images.
