Life originated in sea and has evolved enormously since then. Oceans provide a myriad of opportunities to the people with a photographic eye with the diversity that covers every inch of the expanse. Super macro photography is close-up photography where the image projected on the camera sensor is greater than the original size of the subject. This is also defined as capturing images with reproduction ratios greater than 1:1.
This extent of resolution is however achieved by combining the normal close-up lens with additional specialized tools to obtain a ratio of 2:1 or greater.
