Hey, not long ago, I got a new camera, the Canon R8, and one of the features I was excited about is focus stacking. In short, the camera takes multiple photos, automatically shifting focus on each shot, and thus shifting the depth of field. Later, in the camera body or using software, you can merge these photos together to create a very sharp image while maintaining a beautifully blurred background (bokeh).

Usually, to achieve a larger depth of field and fully include your subject, you need to shoot at an aperture of f/11 or smaller. The drawback is that your background becomes more visible. Why is this a problem? Firstly, you need to spend time arranging the background. Secondly, it's very hard to isolate or separate your subject from the environment.

Now, I can place any object on a table and shoot at f/2.8 or even f/1.4 without worrying about anything being out of focus. This not only saves a lot of time but also allows for stunningly sharp images with a beautifully blurred background.

Check out the samples: the first photo focuses on a cable, the second photo focuses on an adapter, and the last photo uses focus stacking.

This tech is also handy for a regular macro I tend to include in my reviews.
