The rail weighs 1.3 kg and the maximum travel length is 100 mm with a minimum step of 1 micron (1/1000 of a mm).

In the field, it can be controlled via Bluetooth using an app for Android or iPhone and powered by a battery pack (not included, although the cable is). The computer connects to the control box via USB and the box connects to the camera via USB and to the rail with a custom cable. In the studio, the rail is controlled from your computer, either Windows or Mac. Your order includes the rail, quick-release camera mount, control box (16 x 5 x 2 cm), power supply, necessary cables, printed instructions, and a cute little 6-inch tripod with a clip at the top for holding your specimens. My order came in less than 2 weeks, very securely packaged and in perfect condition. The WeMacro rail is made in China and they have no distributors that I know of, so your order comes directly from there. A few moments later it is finished and your image stack, saved on the camera’s SD card, is ready for processing.įigure 2. Focus on the near point, program the controller for 0.25 mm steps over 2 cm (80 steps in this case), then click Run and the rail gets to work. You have determined that your subject-an insect, say– is 2 cm in-depth and you estimate, based on your optics, that a slice spacing of 0.25mm (250 microns) is adequate. The movement of the camera is performed by a precision stepper motor and the movement as well as the shutter release are controlled digitally by a dedicated controller, an attached computer, or a smartphone. Performing focus stacking manually is a challenge, and many photographers have turned to automated rails.

Specialized software extracts the in-focus part of each image and assembles them into a single output image where everything, front to back, is sharp. You end up with a stack of a few to hundreds of images. Then you move the camera forward a small step at a time, taking another photo at each position until you have reached the furthest part of the subject. In a nutshell, you focus on the nearest part of the subject and take a photo. Focus stacking is a technique to overcome the inherently shallow depth of field in macro/microphotography.
