I have a Mac.
The software is essential.
Color cameras use small color filters over 2×2 pixel regions to acquire color information about their images. By doing so they trade spatial resolution for color information.
“Shoot Now, Focus Later” cameras use small lenses over small pixel regions to acquire depth information about their images. The software then processes the data to focus at the desired focal depth. By doing so they trade spatial resolution for depth information.
We’ve had students build these in our labs, so I’m anxious to see how well one works that has been built for consumer applications.
