# MEMENTO Focus Stacking ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/127/638/medium800/camera_flower2_set3.jpg?1707756167 focus stacked macro) Just like our eyes, cameras can focus at different distances, but not all distances at once. Hold your hand up in front of your face and look at something far away -- your hand will appear blurry. Now focus your eyes on your hand and the background will blur. Camera lenses and sensors do the same thing. ### Focus Stacking But we don't have to put up with reality! We can take a series of photos with the MEMENTO, each with a different focal length, and then use some clever software to combine them into a single, in-focus-at-all-distances image. This is especially useful when taking close-up macro photographs, such as the flowers seen here. In this guide we'll cover focus stacking as well as two other neat tricks -- rack focus and split focus -- you can do with the MEMENTO. These are the extremes of the far- and near-focus shots taken to stack into the single image seen above. Hover your mouse over the two thumbnails to see the larger image comparison. Below is the sequence of images used for the full focus stack. ![camera_img0115b.jpg](https://cdn-learn.adafruit.com/assets/assets/000/127/705/medium640/camera_img0115b.jpg?1707931039) ![camera_img0134b.jpg](https://cdn-learn.adafruit.com/assets/assets/000/127/707/medium640/camera_img0134b.jpg?1707931071) ![](https://cdn-learn.adafruit.com/assets/assets/000/127/676/medium800/camera_focus_frames.jpg?1707849072) ![](https://cdn-learn.adafruit.com/assets/assets/000/127/642/medium800/camera_mementoFlowers.jpg?1707757181) ![](https://cdn-learn.adafruit.com/assets/assets/000/127/683/medium800thumb/camera_figrow3.jpg?1707877389) ## Parts ### MEMENTO - Python Programmable DIY Camera - Bare Board [MEMENTO - Python Programmable DIY Camera - Bare Board](https://www.adafruit.com/product/5420) Make memories, or just a cool camera-based project, with **Adafruit's MEMENTO Camera Board**.
