Focus stacked micro-gigapan

Here is the first focused stacked micro-gigapan. It is composed an array of 16 images, each of which is composed of 20 images that are focus stacked. 320 images were taken to make this image, which is only 0.11 gigapixels

Here is another image to compare this focus stacked gigapan to. It is a 4x4 array stitched together, but instead of using the focus a single image. As you can see it is stacked images, we instead just used not nearly as in focus as the image above.
