The picture shows a great lighting. This taken was taken from somewhere between a lower and middle angle. We use the lighting meter to point it at the angle where the picture should be taken. I think we either change the ISO or the Aperture to make the camera quality better. It shows more details of the Lily.
ISO controls quality with 100ISO being the best quality.
Aperture controls how wide the lens opens during the exposure. A wider aperture will let in more light.
