Smoothing defines how the sharp areas are combined. It gives good results in complex cases (intersecting objects, edges, deep stacks) but increases contrast and glare.Īnd there are some parameters require while using this software.Īll focus-stacking algorithms find and combine the sharp areas. Uses a pyramid approach to image representation. This method requires that the images be shot in consecutive order from front to back or vice versa. Which of those methods will work the best depends on the image, the number of images in the stack, and whether the images were shot in random or consecutive order.Ĭomputes the weight for each pixel based on its contrast, after which all the pixels from all the source images are averaged according to their weights.įinds the source image where the sharpest pixel is located and creates a "depth map" from this information. There are three algorithms for focus stacking using this software: methods A, B, and C. And it allows the user to alter the output based on a number of settings, algorithms, and parameters. Helicon Focus is very easy to use and produces stunning results with its default settings. Helicon Remote (Remote camera control, automated focus / exposure bracketing, time-lapse) Helicon Focus (Focus stacking and 3D model building) So it produces results superior to Photoshop. But, Helicon Focus is a dedicated and specialized software used for focus stacking. So it’s slow and the results are not always perfect. But it is not specially programmed for focus stacking. So why do you need another software? Yes, you can. You can use Photoshop for focus stacking. But it can also be used for other types of images, such as landscapes, gardens, still-life photography, and even architecture. Helicon Focus is a fantastic software from Helicon Soft that was originally designed for macro photographers. Helicon Focus Software for Focus Stacking? Then you can use software to blend all the sharp areas together and produce a completely sharp image. To use this technique, you have to take several images of the same scene, focusing on a different part of the subject for each shot. It is a digital image processing technique that combines multiple images taken at different focus distances while blending the in focus areas of the images to increase the perceived depth of field. On the official website you can find several detailed video lessons, as well as the program has a Russified interface and help.Focus stacking is used in many genres of photography, but it’s perhaps most commonly used in landscape and macro photography. Process photos from microscopes equipped with cameras and much more. Take photos with a sharp foreground and background in situations where there is no other way to do so. This method can be used not only to make macrophotographs with enlarged GRIP, but also to create the effect of vintage portraits taken on large-format cameras. If you want to configure image processing parameters in detail, retouch and add text or ruler scale. Then you can simply drag the received images into the Helicon Focus program and it will automatically combine all the sharp parts of the photos into one image. Next, move the focus ring gently over the sharpness area and take photographs until the focus area passes through the entire subject. In practice, everything is simple: you need to fix the camera, for example, by setting it on a tripod, in most cameras you will have to turn off the automatic focus, and if you take off the macro, you should activate the appropriate mode. The right process is called stacking by focus. The mechanism of something similar to gluing panoramas, but the images are not located horizontally with a little overlap, and go as though deep into, superimposing one on another. The main principle of its work is to combine the sharpness zones on several images. In this situation Helicon Focus will be indispensable. You can of course extend the depth of field, close the aperture completely and face a number of other problems, such as lack of light, slow shutter speeds and loss of sharpness due to diffraction, especially on high-resolution cameras. For example, the very famous Canon EF 100 f/2.8L macro lens will have a 1.1 mm GRIP when shooting from a distance of 10 cm. This is not surprising, the width of the GRIP, especially when shooting macro rarely exceeds 1-2mm. It is often the case, particularly in macrophotography, that the object being photographed does not fit into the sharpness zone. The depth of the sharply depicted space, or GRIP, is the area in the photograph that is in focus. Helicon Focus is a program for extending the depth of field limits in photos.
