Isolated Coral

Digging through one of my sands I can always find something interesting. This is a piece of coral I took a macro picture of. I changed the macro setup to get 3.8:1 magnification ration so the entire frame captures only 6.2mm across.



All the location specific pictures I take are 12.6mm wide.

I am working with a Nikon D7000 which has a 23.6 mm × 15.6 mm Nikon DX format RGB CMOS sensor.

To it I attached a Lester A. Dine 105mm f/2.8 Macro 1:1 lens. Having only this 1:1 lens, the best picture I would be able to take is 23.6mm across.

I followed this by adding a set of lens extension tubes between the body and the camera which increased my macro from 1:1 to 1.8:1 and so I thus I can see 12.6mm across on the whole sensor: 4,928 × 3,264 (16.2 effective megapixels)
