To change the alignment parameters, go to the Main Menu, open the "Preferences" dialogue (Main menu → Edit → Preferences.) and switch to the "Auto adjustments" tab.Ī best tutorial about Helican Focus 8: SamplesĬlick on the images to see the original files provided by the Helican soft. These define how much the program is "allowed" to adjust vertical and horizontal positioning, angle of rotation and magnification of images in the stack. If your camera (or subject) moves between shots, you may need to increase the values for the alignment parameters. At that point, stop increasing the radius, so as to preserve as much detail as possible. In general, if you have a halo effect, try increasing the radius until doing so helps to minimize halo. Increasing radius can help get rid of or minimize halo. If your image has fine details and thin lines, as most images do, a low radius level (3-5) will probably yield the best results, although you will probably get more noise and a halo effect. Next try to increase the value to get rid of any noise or artifacts, particularly halos along the edges. Start from the default value and then set it to its minimum and see what happens. We mostly advise you to try different values. Radius is the most important parameter for processing. High smoothing will result in a slightly blurry image without any visible transition areas. Low smoothing produces a sharper image, but the transition areas may have some artifacts. 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. Focus stacking is used in many genres of photography, but it’s perhaps most commonly used in landscape and macro photography.
