Stepper for macros.

It’s a little strange to be writing a column about macro photography when I just sold my Canon 5D and 100mm Canon Macro to a good home. Still, I found myself sharing some details about Helicon Focus with the new owner and notice that Helicon’s web site now refers to a device named the StackShot. This is a focus rail with a built in stepper motor which allows movement of the camera toward the subject in predetermined steps, all set on a small LCD controller.

I have not used the StackShot so cannot comment but what little there is from users on the web it seems to be a solid device. The value of such a device is with very small subjects – bugs say – where the camera movement between snaps has to be extremely small, owing to the high magnification and small size of the subject. The StackShot’s inter-photo interval can also be varied to permit proper recycling of a flash tube if you use one. The resulting images are then stitched together using HF in the usual way – a process rendered trivially simple by this superb application.

You can see an excellent video of the device in action, made by the manufacturer, by clicking here.

The maker says that steps can be as small as 0.01mm and while it’s not cheap at $475, it does look like just the thing for those special subjects. For another $50 there’s a version with a USB port allowing control from your laptop, but I cannot figure out from the operating manual on their web site whether the software runs on OS X on a Mac.
