This is a site that shows the camera feed full screen and inverts in with css

https://nega.radioac.dev/

I hacked it together in half an hour to give people a way to look at the uninverted version of my inverted analogue photos with their phones at exhibitions. most people were more excited to play with it on their phone than by the photos I took days making. :'(

Note that this uses the JavaScript MediaDevices API to stream the camera, which is different from OP's link (which is a file picker input that launches the mobile camera instead of going to the photo gallery)

However, ‘filter: invert(1)’ on top of the OP’s approach should do the same.

OP's approach doesn't display the camera image on-page at all.

Doesn't show my actual camera but a virtual one. So I guess it would need an option to select which camera to use.

I'm getting a blank screen on Firefox for Android :(

do you perhaps have the phone laying on a table? that's what it was for me hahahaha

I also had a blank screen. I found that I had denied camera permission for Firefox at some point. Keeping it that way

It asked me for permission, then just worked, also Firefox for Android

Agreed! Don't see anything.

Works for me on the same.

That is awesome! I don’t blame your guests for wanting to play with it :)

I'm getting a cert error. Subject is *.fortinet.com, not nega.radioac.dev.

Edit, the second: Disregard. It's definitely a corporate middlebox on my end.

fortinet is a cyber security software company, that makes a product called fortigate that does SSL MITM to decrypt and monitor/filter your traffic. Probably want to poke your IT team or get very concerned about your ISP...

Maybe you're behind a firewall with some filtering, and it doesn't like the domain name or something? browsers treat '.dev' domains a bit more strictly than the norm, so the browser doesn't like the redirect?? that's just my guess sorry.

Can you elaborate on how browsers treat .dev differently? its the first im hearing of this and it sounds interesting, thx.

The entire TLD is on the HSTS preload list, so .dev domains are only accessible via HTTPS. You can't use them unencrypted.

My guess is that some corporate filter blocked it because of the "nega" subdomain. Kind of sounds like the racial slur.

Edit: it doesn't help that the domain is `radioac.dev`. So *NEGA.R*adioc.dev

Nah. It's in the Fortiguard category "Newly Observed Domain". So, it hasn't been classified yet, and that person's corporate filter was setup to block those pages.

Wouldn't that be a ridiculously dumb heuristic to employ?

Who ever said corporate IT was smart?

Another view of it: Someone in Management sent a message something like "Stop pointing me to the Scunthorpe Problem wikipedia page[1], just block all these sites" directive and this was the easiest way to resolve it permanently.

Maybe because it’s close to ‘mega’ and all those variants of what used to be mega upload are like whackamole.

Works for me.

Hey, get back to work!

Do you have a link to any of your photographic work?

I'm always too lazy to make an online gallery, and I don't want HN knowing my instagram. But I just made a few snaps of what I had around and put them here. https://golden-taffy-476b64.netlify.app/photos_m/

I really appreciate that you put those up, there's something about the silhouettes of the two figures (2) that I really like.

Thank you. #2 is the most recent of these. It was made by projecting an iphone screen via a toy mirror and lens projector directly onto photo paper. Maybe it was influenced by this exhibition, https://topmuseum.jp/e/contents/exhibition/index-4040.html and Barbara Morgan that I saw there http://www.artnet.com/artists/barbara-morgan/4

It said with just HTML.... that site requires Javascript.
