Macro. It’s what they call it. Macro means large to me. It is counterintuitive to me. But the art or style is to get the details. And believe me the details are often not obvious on first look.
Red coral has hair – like the fine hair on your arm. Not obvious. I don’t know what the purpose is. I don’t see the hairs on most coral.
Horns – rhinopores. The yellow orange are pretty obvious. And the serrations are a new discovery since I now get magnified views with my super macro lens. The black and white – gee! – I didn’t know there were rhinopores for three years. There is a front and back! Damn! Starfish – fine details – it was out because the water was so murky the starfish was fooled into thinking it was dark. This is stuff that I simply never appreciated till I started macro photography. Neat!
