I have recently discovered a really interesting fact and I've been trying to work it into one of my articles for quite some time.Here it is!Did you know that giraffes are blessed with exceptionally good eyesight? In fact, their eyes are the physically largest of any land mammal. But they don't hear too well.Rhinos possess really good hearing, however rhinos can't see worth a darn.Wouldn't it be nice if they hung out together? That way the giraffes could keep an eagle eyed lookout for predators. Any potential problems they don't see coming, the rhinos might hear.They would protect each other and both of them would be safer as a result. Like I said, wouldn't it be a great idea if rhinos and giraffes hung out together?Guess what, they DO! Herds of giraffe will almost always be accompanied by a rhino or two! It's a symbiotic relationship that works well to give them both the results they want - security!In your pictures, there is a symbiotic relationship too. It is the relationship among shutter speed and aperture. To make stunning photos, each of them has to be considered.They work together - always. However, not necessarily to the best advantage. For example, on automatic settings, your camera is going to choose a shutter speed that will eliminate camera shake.Then the aperture is defaulted to the one that works with the chosen shutter speed. No consideration is given as to whether those settings work to create an artistic photograph.True that it is still a symbiotic relationship, neither of them is benefiting.Learn how they work together and how YOU can take the camera off automatic and start to "WOW" your friends with your photography.
