When you know your camera’s disadvantages, you can use them to your advantage. I’ve found mine has trouble focusing on small bright shiny objects for macros. Too close and it wants me to turn on the flash. Turn on the flash and it won’t focus on the object, or it’ll wash it out.
For this photo I managed to balance all the exceptions to get a spacey science fictiony new agey album/book cover of an orb, slightly out of focus. With the albedo, it looks like it could be a moon of a gas giant.
I used a frosted glass marble on white paper in low lighting with the flash off. No editing was done except for the signature.

May this pun be the worst thing to happen to you this year.
