I doubt it got as far as a real technician.

The artefacts remind me of the well-documented artefacts caused by Sony's lossy compression: RawDigger: detecting posterization in SONY cRAW/ARW2 files | RawDigger I wouldn't refer to either of ...

I did some similar experiments a few years ago. You may find that an earlier process version in ACR (Process Version 2, previously called Process Version 2010) will behave correctly when the ...

It creates a counterintuitive effect! Mark

Wow, that is fantastic! Mark

It's a very sad loss. I've learnt so much from folk on this forum. They have aided me immensely in the diagnosis of some of the weird and wonderful processing that goes in inside DSLR/Mirrorless ...

You could certainly plot the camera primaries on a CIE 1931 diagram but what would that tell you?

The heights of the bars shown for each channel on the Colour Response tab are the rows of the inverse of the Color Matrix. So, for instance, for the Samsung NX1 the CIE-D50 color matrix is given as: ...

If you are opening your files in a typical raw converter such as the Photoshop/ACR or RawTherapee to save as JPG or TIFF then it most definitely makes big changes to the data values and the ...

That's me :) Good luck with your project! Mark

The title of this thread probably won't necessarily attract the right people because, to be honest, few people are interested in the "star-eater". Why not start a new thread with a direct title ...

That's right - many cameras do this in low light situations. If that's a problem then it's best to process the raw files because it gives the user better control. Mark

This looks like a small error in the black point. Are you using the raw data? Mark

The brightness of comets is notoriously difficult to predict. That's why it's always best to find a lightcurve of recent observations.

The Comet is MUCH brighter than mag 10.5 Current observations (see link) put it at around 6.5 https://www.cobs.si/cobs/comet/obs/2323/

Jim Kasson discovered similar behaviour on the Nikon Z6: https://blog.kasson.com/nikon-z6-7/mp-dont-matter-for-printing-or-do-they/ I quote: "It is clear that the antialiasing in the Z6 is more ...

For what it's worth, I doubt the reduction in noise at exposure lengths of 1sec (and longer) is because of algorithmic noise reduction or algorithmic hot pixel suppression. The reduction in noise ...

Bortle 9? That's a good result for Bortle 9.
