I thought I would post some square macros. As stated before my definition of macro (traditionally 1:1 or life size) also includes images that are taken close to the subject but not necessarily 1:1.
There are many variations of water drops on blades of grass or plants. A bit like images of clouds, you could argue that each one is unique, the water, like the clouds are transient and would be difficult if not impossible to capture at a later date.
Here is another one.
Arching leaves like this one pose a challenge to the photographer. In a form over function like dillemma, the point of focus is open to interpretation and consequently will affect the out of focus areas as a result. One way around this would be focus stacking, depending on what you are going for. Personally I’m happy with out of focus areas in my images. Others might focus stack for front to back sharpness.
Insects provide another example of being able to choose what areas you want in focus. The generally accepted method is to focus on the eye. With macro and the resulting razor thin depth of field a choice has to be made as to at what point things become less sharp. Focus stacking can be handy here if you have an agreeable subject.
Most insects I come across tend to have a time limit on posing for the camera though 🙂
