Daddy Longlegs

I am continuing to experiment with macro photography by using extension tubes, a medium JOBY GorillaPod with a Monfrotto ball head, and careful manual focusing using the zoom on my lenses as opposed to the focus ring. When using extension tubes it is easiest to set the focus ring and then zoom to focus. The reason for it is simple – if the focus ring is used then the camera has be a very specific distance from the subject, but if the zoom is used to focus then the camera can be positioned over a broader range of distance from the subject, which equals flexibility.

Another interesting thing about macro photography with extension tubes is that the subject is roughly the same size no matter if the camera lens is at 270 mm or 70 mm – the only variable is how far away the front of the lens is from the subject. The extension tubes determine how much of the frame the bug or spider is going to occupy and the lens determines how close or far away you need to be from the bug or spider: more ext. tube = greater magnification, longer lens = farther distance from subject.

I absolutely love this picture. I suppose another interesting picture would be if Sarah had photographed me taking it – lying prone on ground stretched out behind a camera/tripod/cabled remote shutter while donning a bucket hat and a grin.

And at 100% crop:
