A young Hyena (Crocuta crocuta) pops its head above the parapet. There is no telling the difference between male and female in this species, which is perhaps famous for its ‘hermaphroditism’. This, some believe, is an outcome of female dominance and aggressiveness in the competition to secure food for their young. It is said that females actually outpace males in testosterone production and grow larger and are more aggressive than males. The male looking external genitalia of females is unique in this species.

F-stop, is a lens aperture setting measure which all variable aperture lens are calibrated. The measure provides an indication to the users of the amount of light being transmitted through the lens. Each stop change either halves of doubles the amount of light on the film or sensor. The f-stop setting also determines the depth of field on the subjected in the image.
“When I first started learning how to take photographs, you had to spend the first six months figuring out what an f-stop was. Now you just go and take pictures. Nobody thinks about technical issues anymore because cameras or camera phones take care of that automatically. ”
