Helicon remote wifi canon7/25/2023 Setup 3: all of the above, but with the addition of a tethered computer and software that can assess the deepest and the shallowest slices then compute the number of intermediate slices required to get a sharp image the software may then guide the photographer in collecting the slices or it can control the sliding rail system directly.Setup 2: all of the above, but with an addition of a sliding rail system that allows for minute movements of the camera forward or backward eliminates the need to adjust the lens focus distance this railing system can be manually adjusted or electronically controlled it may provide more precise control since there are increment markings on the railings.Setup 1: a tripod, with lockable, heavy duty, steady legs and head a remote conrol for triggering the camera a steady hand on the lens to be able to move the focus distance in small increments, adjusted by hand.There are four setups that work well, depending on budget, the level of precision required and the level of comfort and control desired: For most people, including me, creating millimeter progressive slices requires some extra equipment. And some photographers simply prefer to have full control of the process.Īs an older photographer, there are definite limits on what I can do manually. Of course, there is also overall expense. Some subjects are fleeting, like snowflakes. The more equipment that is needed, the more cumbersome is the setup, especially outdoors. He has developed his method over many many hundreds of hours of practice. One such photographer is Don Komarechka, who is a local nature, macro and landscape photographer.ĭon’s macro images are stunning and equisitely detailed. By manually, I mean by handholding the camera rigidly to their body and gently, subtly rocking back and forth on their heels so as to bring the back, middle and front of the subject in focus in successive frames. Some photographers are able to collect the images manually, which I find amazing. There might be a hundred images needed to fully cover the subject from front to back. Remember that depth of field problem? For a relatively complex subject with lots of bends and twists, the focus distance change needed from one slice to the next might be a few millimeters. Until we discover just how difficult it is to collect the slices. Great – sounds like the perfect solution. With today’s post production software, another option is to take a series of “slices” at different focus distances, passing through the full depth of the subject, then using the software to combine multiple images into one. But that will never completely eliminate the problem, since the resulting photograph is a two dimensional image of a three dimensional subject. Rotating or repositioning the subject or the photographer can help substantially. The first step is to minimize the overall subject depth required. The images are displayed side by side.īut if tack sharp focus is the goal across the entire subject, a few steps are needed. The shots then become a series – the edge of a leaf, the curve of a petal, the backside contour where petals meet stem. Some photographers handle this by breaking the shot into multiple shots, each one showcasing a different feature. Few natural objects have a single “important feature”. But the complexity of most macro subjects can make this very challenging. Selective focus can be an artisitic choice, highlighting the single most important feature of the subject. The answer, like many things in life, is “it depends”. But macro lenses have an amazingly small depth of field, almost guaranteeing that some part of the image will be out of focus. Macro photography requires only one unique piece of equipment: a lens that can focus within a tiny distance of the subject, resulting in an image that is the same size on the camera sensor as the subject is in real life. Macro photography reveals the smallest of these subjects, from tiny lichens to the wing details of insects to the inner sculpture of a summer bloom. New life all around us, providing a wealth of photographic subjects.
