What is wrong with this picture

What is a TG-1 anyway? Can’t remember having heard of it. Well, I see from the focal length in your image’s EXIF data that it’s a compact, but that’s it.

And yes, tiny sensor, underexposure, high ISO—no surprises here. And whatever you do, you will either drown the landscape or blow out the moon… unless you take two shots, one exposed for the moon, the other for the landscape, and combine these two in post-processing.
