Is it normal to have black spots on the corners of a RAW photo?

I took a raw photo and dragged it onto my computer. It looks very different than on the camera. There are black spots on the corners and the overall photo looks much uglier than on the camera itself. Is that normal? (Have a Surface Laptop 3 and a Sony Rx100 m6 if that helps)

Hm… I only take photos in raw format. My photos have never had anything like this.
In addition, it looks in the photo as if it had been photographed from a window, for example, and the (window? -) frame can be seen in the corners.

It is clear that the photo looks different on the laptop than on the camera… It is a completely different format and the laptop has a completely different resolution and color than the camera.

What kind of a photo is this… It is probably not a night shot, although the white dots imply that they are stars?

That looks like vignettes; did you use a sun visor or other accessories? The vignettes have nothing to do with Raw on an RX100.

The reason that a RAW image looks worse at first is because all of the automatic settings required for a jpg are missing. You can then make them better / more beautiful / individual.

This is a night shot and normally my pictures never have such corners. And no there were no window frames

No had no accessories. Is my kamra broken?

Yes, it is completely normal. RAW, that is raw data, recorded through a round camera lens. You have to develop a RAW first, and then lens correction is part of the development. After the correct lens correction, the black corners are gone.

Still, it doesn't belong there.

It looks like you are using a full frame camera, but a lens that is not designed for it.

With a long exposure it is probably just a blatant vignetting that is on all of your pictures, but only becomes visible through the long exposure.

This is a bridge camera

This is normal for Sony toy cameras.

No, seriously it seems to happen with certain cameras or lenses from all manufacturers.
They have probably started to put lenses on the cameras that can't completely fill the image circle in the wide angle. And that is then compensated for by software so that they can claim that the camera has 1-2mm more wide angle than it actually has. Everything a marketing thing…

If you want to construct a wide angle and save money, then "that" belongs there!

Any sensor will have it too…

I can't judge from a distance like this, I'm sorry.
