The universe is more than 13 billion years old. But what did it look like when it was only a year old?

Lets say we were to send an indestructible camera back in time a couple billion years in order to take some pictures/video of the universe as it looked exactly one year after the Big Bang. What could we expect to see? What about after ten years? A hundred? A thousand? A million? How long would it take the universe to start looking like it does now?

That would be in the middle of the photon epoch, where the entire universe was a super hot and bright plasma soup consisting of photons, protons, neutrons, and electrons.  It was far too energetic for matter to properly form, so even if you did send a camera back to that time it would be vaporized instantly and become part of the soup.  But if you were to Gandalf your way around the laws of physics in order to send the camera back in the first place, you'd just see a bright white light everywhere.  It would take about another million years for things to cool down enough that space became transparent, and atoms could start coming together.
