Focus stacking

Take advantage of focus stacking in photography

Focus stacking is a technique used in photography to achieve greater depth of field in an image. several images of the same setting, each with a different focus point, and combined into one image using special software. The process of the process that all areas of the subject from the foreground to the background are sharp and accurate, this end result is larger.

This technique is used a lot in landscape and macro photography. Especially in macro photography, the technique is very useful. In macro photography, the depth-of-field area is reduced a lot, as focus stacking of images is very useful. Adobe Photoshop, Helicon Focus or Zerene Stacker can be used to stack the images themselves.

There are generally two ways to take pictures:

1: Manual method:

  • place the camera on a tripod to ensure stability.
  • determine the area you want to photograph and set the focus points needed to capture the full depth of field.
  • take a series of photos, manually adjusting the focus between each shot to cover the desired area.
  • transfer the images to a computer and use image processing software to align and stack the images.

2: Autofocus bracketing:

  • some cameras offer an autofocus bracketing feature that automatically takes a series of shots at different focus points.
  • see your camera's manual for how to activate and adjust autofocus bracketing settings.
  • transfer the images to a computer and use software specially designed for focus stacking (e.g. Helicon Focus, Zerene Stacker).

Macro photography often uses a macro focus rail, especially if a manual lens is used.
