This has been floating around for a while now. Max Lyons has created the first digital photograph with over 1 billion pixels.

What he’s done is stitch together 196 6megapixel images to create a single shot. Combining images to create larger pictures isn’t new - it’s particularly useful for panoramic shots, or in tight spaces where you can’t get a wide enough angle or move any further backwards (due to pesky things like walls.)

But why bother?

Max’s answer is quite simple

‘”why not?” …. there has been speculation about when gigapixel images would become possible. This seemed like an interesting challenge to me. ‘

So there you go.
