Closeup of wine cork

I enjoy shooting closeup images. But shooting closeup images normally presents the photographer with a few problems. At such close focus, the depth of field (i.e. portion of the subject in focus) is very shallow, which will require either very small apertures to increase the depth of field or photographing each section of the subject separately and then stacking them together in a dedicated focus stacking program (need very stable system).

I have been building a setup capable of doing this, and hence I thought I would try this with the wine cork. My preferred program for focus stacking is Helicon Focus, as Zerene stacker did not work well for me when I trailed it.

I used my Olympus E-M5 and Coastal Optics 60mm F4 APO lens to shoot these images. My aim was to get all of the cork in sharp focus and I have achieved it. My setup is now steady enough that adjusting the focus between shots will not introduce any shift of the subject on the image (the subject remains at the exact same position for each and every image taken), which will help the stacking process.

The details that can be seen in the 100% crops, is a testament to how sharp this lens is and how well the stacking worked. In future, I will try extreme macro (> 1:1 magnification) by using one of my bellows – that will truly test the stability of the system and the ability of the lens and camera to resolve the fine details.
