Focus Stacking
Focus stacking is a technique used in photography to achieve an image with sharp focus from front
to back. The technique involves taking a series of photographs, each with a slightly different
focal point, and then blending them together using software to create one final image with a depth
of field that is impossible to achieve in a single shot.
At Visionary Photography Workshops, focus stacking is one of the many techniques we teach our
participants. It is a powerful tool for landscape photographers, macro photographers, and anyone
who wants to achieve stunningly sharp images.
In this article, we will take a closer look at focus stacking, its benefits, and how it can be used
to create breathtaking images.
What is Focus Stacking?

Focus stacking involves taking multiple photographs of a subject with different focal points, then
blending them together in post-processing software to create a final image with a sharp depth of
field.
For example, when photographing a flower close up, the camera’s depth of field may be too shallow
to capture the entire flower in focus. However, by taking multiple photographs, each focused on a
different part of the flower, we can combine them in post-processing to create a final image that
is in focus from front to back.
The process of focus stacking involves several steps. Firstly, the photographer must choose the
appropriate aperture and shutter speed for the shot. A smaller aperture (higher f-stop number) will
create a larger depth of field, while a faster shutter speed will reduce the risk of camera shake.
Once the appropriate settings have been chosen, the photographer must take a series of photographs
with different focal points. This can be done by manually adjusting the focus point between shots,
or by using a focus stacking rail to automate the process.
Finally, the photographs are blended together using post-processing software to create the final

image. There are several software options available for focus stacking, including Adobe Photoshop,
Helicon Focus, and Zerene Stacker.
Benefits of Focus Stacking

There are several benefits to using focus stacking in photography. Firstly, it allows photographers
to achieve a depth of field that is impossible to achieve in a single shot. This is particularly
useful for macro photographers, who often need to capture very small subjects with a shallow depth
of field.
Secondly, focus stacking allows photographers to create images that are sharper and more detailed
than they would be able to achieve with a single shot. This is particularly useful for landscape
photographers, who often want to capture as much detail as possible in their images. Finally, focus
stacking can help to reduce noise in photographs. When shooting with a smaller aperture, it can be
necessary to use a slower shutter speed to achieve the correct exposure. This can result in image
noise, particularly in low-light conditions. By taking multiple shots and blending them together,
photographers can reduce the need for a slow shutter speed and therefore reduce noise in their
images.

Using Focus Stacking in Photography

Focus stacking can be used in a variety of different types of photography. Here are some examples:
Landscape Photography: When photographing landscapes, it can be difficult to achieve a sharp depth
of field from front to back. By using focus stacking, photographers can ensure that all elements of
the landscape are in focus, from the foreground to the background.
Macro Photography: Macro photography often requires a very shallow depth of field to achieve the
desired effect. By using focus stacking, photographers can create images that are in focus from
front to back, while still maintaining the shallow depth of field that is characteristic of macro
photography.
Product Photography: When photographing products, it is often necessary to have the entire product
in focus. Focus stacking can be used to achieve this, ensuring that all elements of the product are
sharp and in focus.
Portrait Photography: Focus stacking can be used in portrait photography to achieve a sharp depth
of field, particularly when photographing groups of people
By taking multiple shots with different focal points and blending them together, photographers can
ensure that all individuals in the group are in focus, even if they are standing at different
distances from the camera.
Wildlife Photography: Wildlife photographers often need to capture fast-moving subjects. However,
this can be challenging as it can be difficult to achieve a sharp depth of field while keeping the
subject in focus. By using focus stacking, photographers can take multiple shots of the moving
subject with different focal points and blend them together to create a sharp final image.
Tips for Focus Stacking

Here are some tips for successful focus stacking:
1. Use a Tripod: To ensure that all shots are taken from the same position, it is essential to use
a tripod. This will also help to reduce camera shake and ensure that all shots are sharp.

2. Use Manual Focus: When focus stacking, it is important to use manual focus to ensure that the
focus point is consistent across all shots.
3. Use a Focus Stacking Rail: If you are planning to do a lot of focus stacking, consider investing
in a focus stacking rail. This will automate the process of adjusting the focal point between
shots, making the process quicker and easier.
4. Shoot in RAW: Shooting in RAW will give you greater control over the final image when it comes
to post-processing. This is particularly important when focus stacking, as you will need to adjust
the exposure and color balance across all shots to ensure that they blend together
seamlessly.
5. Take More Shots Than You Need: It is always better to take more shots than you think you will
need. This will give you greater flexibility when it comes to post-processing, and will ensure that
you have enough shots to create a seamless final image.
Conclusion
Focus stacking is a powerful technique that can help photographers achieve a sharp depth of field
that is impossible to achieve in a single shot. It can be used in a variety of different types of
photography, including landscape, macro, product, portrait, and wildlife photography.
