It almost feels like cheating when photographing flowers. They are so beautiful that a great picture is easy to create.
To create the white background, the tulip and vase were placed on a white sweep (an Elinchrom Shooting Table in this case) and a strobe in a softbox was fired into it from behind the subject. The main subject was lit by a strobe in a large softbox positioned to camera right. Having this setup readily available means I can capture subjects such as this tulip with little time expenditure - which is extremely important to me.
This picture also shows that you do not need a macro lens to photograph flowers.
