You may find interesting the article The Ethics of Digital Manipulation by Jerry Lodriguss.
Quite interesting, but I think he goes to far in what he regards as ethical. One pertinent point he does make though, is that every photo is subjective:
The fundamental fact that we usually forget is that when we take a picture we do not make a perfectly objective recording of reality. What we make is an interpretation of reality.
It set me thinking. Galaxies are typically 100000 light years in diameter. They are 3D. They emit x-rays, radio waves, ... And yet we fool ourselves into thinking that a 2D representation on a small computer screen captured with a limited bandwidth is an accurate representation of the object.

Thanks Andres
I am glad to be able to recover this document which I read some time ago but have never been able to find it again. However, I still find it to be quite vague about its actual meaning. For example, we have the statement

The Documentary School only accepts as valid image processing practices those procedures having a documentary basis. Documentary criteria are those intended to communicate some properties of the objects photographed, as part of nature.

OK, so the documentary school only wants to use image processing practices with a “documentary basis”, but there is no really detailed explanation of what is meant by a “documentary basis”

Some years ago, a group of people (including Juan) published a manifesto about the documentary astrophotography. Since then, the web page has been lost, but Google cache can still access it:
http://webcache.googleusercontent.com/search?q=cache:kojS-aFcXMUJ:astro-photographer.org/dsa/statement.html
Since the page is no longer active, I don't know if the people of this group still stands by this.

Hi Juan, Rob –
Do you know if all the module dylibs need to be signed by a certificate belonging to the same team id? I’m asking because I tried signing the StarNet module with my self-signed certificate (which is obviously trusted on my local machine), but still PI doesn’t “see” it. Or maybe is an actual Apple-issued certificate required?

It also has to be notarized by Apple otherwise Gateway will throw it out

General / Re: Issues with Photometric Color Calibration after update
« Last post by johnk on 2020 March 03 19:23:28 »
Ok so an update with this.

Increasing the limiting magnitude to 20 and the aperture to 15 in the photometry tab allowed me to make this work.

Quite odd!

But a happy camper.

Clear skies.

Can you define what exactly what is meant by 'painting' and what context 'painting' would be used....just for clarity?
See, as one example, this thread https://pixinsight.com/forum/index.php?topic=14582.msg87172#msg87172

Both Juan and Vicent frequently refer to “documentary criteria”, but nowhere can I find a definitive statement of what its parameters are. I think I understand what they are getting at, but I’d like some confirmation.
