I took this Orchidaceae while playing with my new speedlight and the macro tube. In this case I used only 1 segment of the tube since I wanted to capture the main attraction of the flower without loosing deep of field. Apperture value was not automatically recorder within EXIF because the macro tubes. I used 11f in manual mode with a 50mm lens.

Tomé esta orquídea mientras practicaba con mi nuevo flash y un tubo macro. En este caso usé sólo un segmento del tubo ya que quería sacar la parte más atractiva sin perder profundidad de campo. No sale la apertura grabada en el EXIF por el tubo macro. Usé 11f en modo manual con un lente de 50mm
