Clipped highlights in digital photography are simply impossible to eliminate in post-processing without conjuring nonexistent information. Even if you shoot raw. Different raw processors use different tricks, color propagation and such, but naturally they are best used when highlights are really small. I would not be surprised if tools like Lightroom invoke ML at the first hint of clipping (because why not, if you al…

— If you think there is “clipping” and the somehow different “nominal clipping”.
Clipping is binary. Either you camera’s pixel clipped (i.e., accumulated enough photons to get fully saturated, and therefore offers no useful information for debayering), or it did not. If it clipped, then you lost colour data in that part of the image. If you lost colour data, and you want a colour photo, then in almost all cases one way or another you will have to rescue it by conjuring information up for the photo to look authentic and aesthetically good. (A lot of raw development software does it for you by default.) If the clipped bit is small, it is easy to do subtly. If it is big, which is a real danger with sun reflection bokeh, then… whoopsie.
— If you think modern sensors are safe from clipping.
This applies to any digital camera, from consumer to top professional models. Sensor bit depth is not even remotely enough to expose a scene with extreme highlights (e.g. sun or its reflections) without taking special measures regarding exposure at capture time. If you don’t tame highlights with a polarizing filter, you must dramatically underexpose the scene or they will clip.

#83Ok I'm getting tired of this habit of deep linking to apps. The apps either override existing web pages featuring the same content, or there's a web redirect to an app I might have installed but am not signed into. So in multiple cases, it's difficult to just read whatever the information is. Web pages are universally accessible. Everyone has a browser on their device of choice. The web is 35 years old. Access to inf…
The nefarious thing is some people will tell you there’s nothing wrong with the link and gaslight you into thinking you’re crazy – because they don’t have the Bluesky app installed.

nah-- even in the supplied jpg the histogram shows they're not clipping the highlights, and if you crank down the brightness, you can see the detail.
1. Clipping occurs in the scene-referred raw camera sensor pixel data at capture time.
2. Raw processing software fills in the highlight by supplying the missing colour information. Often this happens by default.
3. When you obtain a display-referred JPEG, the missing information for clipped highlights was already supplied. Tone curves and other adjustments apply already after highlight reconstruction, making the final result look more organic.
In other words, with modern digital photography processing workflows you will never see any clipping on a histogram for the final JPEG (unless either something went really wrong or it was intentionally done for a look), and it is a poor foundation to make assumptions about what clipping had or had not occurred at capture stage.
What you can safely assume, however, is that a normally exposed digital photo featuring any sun reflections from water or glass will almost certainly have blown highlights.

You may be confused on at least two counts: — If you think there is “clipping” and the somehow different “nominal clipping”. Clipping is binary. Either you camera’s pixel clipped (i.e., accumulated enough photons to get fully saturated, and therefore offers no useful information for debayering), or it did not.

#87So HN, any theories on how this happened ?
Seems like they used some AI tool to remove speckles from an image. The tool has to generate a likely replacement. And one of the speckles looked a bit like a coin.
I must be missing something obvious but I don't see it mentioned in the submission or comments, or perhaps I'm not making the connection

What are you even talking about? It is literally a website.
I have the Bluesky app installed but I'm not logged in. So the website link is also being treated as an app deep link. It opens the app instead of just opening the website. I don't have a lot of familiarity with app deep links, but my understanding is that originally deep links required a special non-domain to be registered that was separate from a normal web url. Somewhere that's changed over the years and now regul…
You might be thinking of protocol handlers, like oacon:// to open something in software installed to handle that (in this case, launching openarena to connect directly from a dpmaster mirror with such application links included). I don't think they were called deep links back then, just different protocols, like http in http://example.org is a protocol that your browser is configured to handle and ftp:// used to be as well
These are still in relatively common use today, but on mobile devices it has become the norm to hijack specific domain names or even a path (e.g. F-Droid will try to handle repositories on third-party domains for you by trying to hook¹ any URL that contains */fdroid/repo/* -- so far, this has always been useful to me, but I can see the flip side). This link hijacking is often a pain for me as anyone linking to any Google product will make my phone try to open some Play Services component, which is largely not functional. I can't get rid of the system component (e.g. replace it with microG) without installing a custom ROM, which I can't do without getting rid of half the device's special features (no point having this phone then), but I also don't want it pinging back to the mothership so... a pain it shall be
As for your problem, reset the app's settings and it'll re-prompt you the next time you click one of these links in which app these links should open. It should do that any time there is (newly) more than one app that can handle any given URL

There also is the ability to register for a URL "scheme" (the bit that replaces "https"), which I believe is what you're thinking of and it does predate the https thing, but both have been around for a while. I'm guessing companies have just gotten more aggressive about using the https one.
Edit: and yes it is annoying, I've uninstalled the GitHub app because of this.
