The unit has been tested and found compatible with a wide number of camera models and lens. The set contains: Helicon FB Tube with IR Receiver and LED Indicator Front and Rear Caps IR Transmitter – connects audio port of a smartphone and Extension cable for smartphone and IR Transmitter.

Helicon FB Tube settings are configured through an additional application for Android or iOS. Helicon FB Tube has no optics and does not affect image quality. Helicon FB Tube needs no additional hardware apart from conventional cameras and lenses. Mounted on the camera in the same way as a usual macro extension tube, Helicon FB Tube automatically shifts the focus by one step with each shot thus producing a stack of images of unlimited length that can be rendered into a fully-focused image.
The measured tube length is 13mm and adds somewhat to the magnification of the lens dependent upon the focal length. Essentially it is an extension tube with integrated electronic micro-controller designed to enable automated focus bracketing in single or continuous shooting modes. This new idea comes from the producers of Helicon Focus, the industry leader in image stacking software. Now comes the new tool on the market- The Helicon FB Tube. There are several choices from several manufacturers to accomplish this movement process. A geared focusing rail (below) or an automated programmed focusing rail are specialized tools for changing the focal point without compromising image size.Īnother system uses a rail incorporated into a bellows system to change focus but not scale, as pictured below. The better approach requires moving the camera a measured increment between shots. Some lenses change magnification as the focus is changes, creating alignment problems. The several images are captured using different points of focus. The image of the bee (below) is an example of a stacked composite of 50 blended images. The images are blended into on in the computer using specialized software.

This requires a series of often many images, each made at a different point of focus from front-to-back. Therefore we have learned to use focus stacking to solve this problem. Thus we are our best enemy and must deal with self-imposed photographic criteria. The final consideration is that when the lens is moved closer, the DoF also becomes smaller. We could select a shorter lens, but that changes perspective and ability to focus close in the case of a macro lens. However we may not be able to make a good exposure with a big F number like F22.Īnother factor is that as we increase the focal length of our lens, the DoF becomes smaller. Insufficient Depth of Field (DoF) is cause by three factors:įirst, we understand that, in addition to exposure, aperture controls DoF.
Many times when producing images of small subjects we find that there is insufficient Depth of Field (or depth of Focus) to render the entire subject sharply from front to back.
