Shot with a Sigma 105 macro and Canon 550 flash. The camera was in manual using the settings below. The high aperture is what creates the black background.
Tv( Shutter Speed ) 1/125
Av( Aperture Value ) 18
ISO Speed 200
Flash On
Great job. Thanks for the settings and values. My camera has some limitations so I would not get the same results as you but I sure appreciate looking at your picture.
Wonderful. I like it that it is dark like this, it is so unusual for a macro of a butterfly. I admire you for having the patience and skill for capturing a shot of these beautiful but active winged beings. Great job. :)
