15 August 2009 Fragmentary Macros

I’ve talked about my potter friend Koji Kamada (鎌田幸二) twice before. This time I asked him for some fragments of broken pieces to play around with and he was nice enough to oblige.

These shots were taken with my ZF 100/2 macro lens, my very crappy tripod (I used a 5 second timer, on the theory that all the wobbles from pressing the button would have extinguished by 5 seconds after pushing the shutter), my SB-900 flash, and a PK-13 extension tube. This 27.5 mm ring is just an empty tube that fits between the lens and the camera. Working on the same principle that when you move a magnifying glass farther away what’s in it gets bigger, this little ring can magnify images by a lot. And, since it’s just empty space in there, there is no loss of image quality. What you do lose is light, and the ability to focus very far away, but both of these are negligible for table-top macro photography.

Since I used a macro lens with an extension ring, what you are seeing are very, very close-up images of these fragments. Unfortunately my Nikon D90 does not glean any photographic information from the lens, but these were all taken between f11 and f16. Even at these small apertures, the depth of field is still incredibly small at this short distance.

Finally, in this series the one that really benefits from clicking to enlarge is the second one, since its horizontal orientation means that it gets shrunk by a lot to fit into the space. And, this is the one that best exposes the boundary between stone and glass (which is really what the glaze is).
