I doubt this is a censorship, or a anti-counterfitting feature. It&#x27;s most likely something wrong with the codec used to display images, possibly 10-bit heif photos are being interpreted as 8-bit jpegs. See other people getting the exact same shade of green in random photos:<p><a href="https:&#x2F;&#x2F;forums.androidcentral.com&#x2F;ask-question&#x2F;912123-photos-taken-today-all-show-solid-green-154kb.html" rel="nofollow">https:&#x2F;&#x2F;forums.androidcentral.com&#x2F;ask-question&#x2F;912123-photos...</a><p><a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;oneplus&#x2F;comments&#x2F;4p2ief&#x2F;pictures_on_op3_saving_as_solid_green&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;oneplus&#x2F;comments&#x2F;4p2ief&#x2F;pictures_on...</a><p><a href="https:&#x2F;&#x2F;forums.oneplus.com&#x2F;threads&#x2F;solid-green-photos.453215&#x2F;" rel="nofollow">https:&#x2F;&#x2F;forums.oneplus.com&#x2F;threads&#x2F;solid-green-photos.453215...</a>

Is there perhaps an invisible anti-counterfeiting constellation [0] on the ballot? Have digital cameras started enforcing that type of optical DRM?<p>It&#x27;s true the envelope&#x27;s closed, but part of the ballot paper is visible through the transparent window.<p>Should the poster be worried about their smartphone reporting them to law enforcement?<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;EURion_constellation" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;EURion_constellation</a>

Does anyone know what is going on here?<p>Is Xiaomi stock camera known for censoring certain documents?

The unofficial Google Camera port I&#x27;ve been using silently discards photos containing the sun&#x27;s reflection in water. Rather than assuming Google is intentionally concealing the appearance of a celestial body, I&#x27;ve chalked this up to a bug in post-processing code that only kicks in when a specific image recognition pattern matches. Modern ML-driven camera systems make for some fun &quot;500 mile email&quot; [0] esque failure modes.<p>[0] <a href="https:&#x2F;&#x2F;www.ibiblio.org&#x2F;harris&#x2F;500milemail.html" rel="nofollow">https:&#x2F;&#x2F;www.ibiblio.org&#x2F;harris&#x2F;500milemail.html</a>

I’ll bet someone slapped a common QR code library in there that also matches other barcode types, made a few modifications and didn’t test the unusual types.

In some countries it is allowed to vote, but your employer or landlord may request you to prove to you that you voted for the „right“ guy by sending them a picture of your filled out ballot.<p>A feature like this (properly implemented) could actually be great for those countries.<p>The slippery slope argument still applies of course.

A question - does Photoshop&#x2F;AfterEffects&#x2F;Premiere automatically embed a similar sort of a &quot;watermark&quot; to e.g. make tracking back meme authors possible? How about cameras?

Modern camera stacks use a lot of machine learning to figure out what kind of scene is being captured; primarily to apply specific tuning for that scene. For example, certain settings are applied for night time, portrait, landscape, beach, etc.<p>Xiaomi might be using an ML detector to figure out it is looking at something that resembles an official document, and refusing to take a picture of it.

The user says that with ProShot it worked, it would be nice if those photos were provided so that we could look for differences.

The title assumes, with &quot;censoring&quot;. A more appropriate title would be &quot;Strange quirk when photographing German postal voting documents with the Xiaomi Camera&quot;.<p>But what a quirk, a real life object causing issues in software.

Let’s have fun with this. Get a copy of the barcode or trigger and we can print it on a cheap line of clothing. Tshirts hats whatever
