|[Note Guidelines] Photographer's Note [French]|
It is probably Phyllomacromia africana, Selys, 1871, characterized among others by different shape of triangles on the front and rear wings, as is visible in the photograph. This differentiates from Onychogomphus.
Some rank it in the family Macromiidae, while for others it is part of the family Corduliidae: it shows that the systematics of Odonata is still not really fixed.
It is an African dragonfly from the humid forest, tropical or equatorial. Its typical habitat consists of the lowland from the rain forest and the rivers surrounding. In fact, the photograph was taken near a pond.
The photograph of the subject relatively mobile was conducted by a sunny morning. Despite the subject's mobility, the device is set to aperture priority mode, with a sensitivity equivalent to ISO-200, a focal length of 8 mm.
The opening was set at f / 4 in order to have enough incoming light and at the same time, make the background neutral enough. With these parameters the rate stood at 1 / 280 th.

Nice picture of this dragonfly with a good light showing us so many nice details. f/4 was a good choice in order to get the bg enough blurry. 2 things: It seems to me that the subject is a little bit squeezed within the frame and I would have removed the whitish patch in the upper right corner of the frame3.
Excellent POV and exposition control...
A fine shot of this african dragonfly. Good composition and sharpness.
