|Each time my camera gear advances, I think about the penny date and can my new
gear do even better.
This time I've added an 18 MP camera body, the Canon EOS 7D, extension tubes and
a Camera Focus Rail. I've also been learning.
Seems my wonderful 100mm Macro lens can get 1:1 images. That means the lens can
display on the sensor an exact 1-to-1 image of the object in front of the lens.
The tip in the Canon 100MM Macro User Manual says to set the focus dial to its
closest focus position, marked 1:1, and move the camera to achieve focus.
Yeah, right, easier said than done. But I read about focusing rails and some are
not all that expensive. The rail that I ordered from Amazon was only $65. It
has 2 6" scales for in and out plus left-to-right precision movement. For
height, the third axis, I have to move either the object (penny) or the camera
tripod post up or down.
The new problem? I got so close, or the image got so big, that one digit is
larger than the target 640 by 480 image that I have set as a standard thru all
these Penny Experiments. In the end, I reduced (resized in Photo Editor) the
digit-image to 640 by 480 to conform.
The next problem is that the digits are taller than they are wide so I turned
them 90 degrees for the first time. Four images form the date: 2011.
