Focus stacking is a technique used in photography to achieve greater depth of field. It involves combining multiple images taken at different focus distances to create a final image with a greater depth of field than any of the individual source images.
Here’s a simple way of how to focus stack:
1. Setup Your Camera: To start with, mount your camera on a tripod to ensure stability. Use manual mode to set exposure settings. Turn off autofocus and vibration reduction if your lens has it.
2. Choose Your Subject: Focus stacking is often used for macro photography, but it can also be applied to any situation where you want to increase the depth of field.
3. Shoot Your Images: With your camera in manual focus mode, take multiple photos of your subject, each time adjusting the focus a little bit further back. Ensure there is overlap in focus throughout your set of photos.
4. Import Your Images: Using image editing software like Photoshop or Helicon Focus, import all your images.
5. Align Your Images: Since there can be slight movements or changes between shots, use the auto-align feature in your software to align all layers.
6. Stack The Images: Use the auto-blending feature to combine the different focus points into one image. The software will analyse each layer and pick out the parts of each photo that are in focus to blend together.
7. Fine Tune Your Image: After blending the layers, you might notice areas that are not perfect. You can use the brush tool or other editing tools to fix these areas.
8. Finalize and Export Your Image: Once you’re done editing, you can flatten your image and export it in your desired format. Remember, the goal of focus stacking is to create an image that is sharp from front to back.
With practice, you’ll be able to create stunning images using this technique.
