Canon Specific Options for Focus Stacking It is generally easier to estimate on the lower end of the number of shots and then simply start the stack again if not enough shots have been taken. Typically large would be used for normal scenes, medium for most close-up or macro work, and small for 1:1 scenes with a smaller f-stop value. The step sizes are the same as the incremental adjustment buttons. Step size can be set as small, medium, and large. The focus stack is configured by setting the number of shots and the step size between each shot. Instead, the user moves the focus position to the nearest desired position. Sony cameras can only use classic focus stacking, most notably all Sony cameras. It is also an option with CamRanger mini and CamRanger 2, and can be turned on or off from within the app settings. Classic Focus Stacking AppĬlassic focus stacking is the method of capture used by the original CamRanger. In these cases, use the Adjustment Factor to adjust the number of shots and step size. The CamRanger does a pretty good job calculating the number of shots, but there may be scenarios where the photographer may want to take more or fewer. Note that the step size does not have any direct real-world equivalent. Pressing the “+” button on the focus tab will expand the tab and show advanced options, including listing the focal length, number of shots to be taken, and the step size between the shots. Access the focus bracketing tab by pressing the magnifying glass button. This method is supported by Canon, Fujifilm, and Nikon. The default focus bracketing method allows the user to set the near and far focus positions and then the CamRanger 2 or CamRanger mini automatically calculates the number of shots and the amount to adjust the focus between each shot. Some options include Photoshop, Helicon Focus, or our personal favorite: Zerene Stacker. There is much debate about the best post processing software for focus stacking. This can be especially helpful for macro photography where the depth of field is very shallow and many shots are required to have more than a tiny portion of the scene in focus. The CamRanger can be used to automatically capture a sequence of images and adjust the focus between each shot. Focus stacking is the process of capturing multiple images with different parts of the scene in focus and then combining them in post processing to increase the depth of field, or portion of the scene in focus.
