Today a Quiz. Here are two super sharp photos of plants from very different families. What are they?
Quiz #1: The top photo is a focus stack of 100 images. In real life the image would be 2mm wide so I think it’s been magnified about 80 times. (This one is hard to guess. It helps to squint your eyes to make it look small.)
Quiz #2: The photo below is a focus stack of 70 macro images. What it is?

p.s. In case you’re curious … Focus stacking is a digital processing technique in which the photographer takes multiple images of the same object at different focal points, then digitally merges the photos to produce a completely in-focus image. The object has to hold still and so does the camera. It requires special software to merge the images.
This video shows how it works.
