You can take TWO screenshots, moments apart, open in GIMP, paste one over the other and choose any one of these laying modes: Lighten, Screen, Addition, Darken, Multiply, Linear burn, Hard Mix, Difference, Exclusion, Subtract, Grain Extract, Grain Merge, or Luminance. https://ibb.co/DDQBJDKR

#112Earlier quoted context omitted.
Clearly, I meant using a camera, and I'm guessing you knew that too
Not the parent but that was not at all clear to me. I immediately thought of taking multiple successive instantaneous screenshots and then stacking them. I'm not sure I would have thought of using a camera within a few minutes to an hour, it's not a tool I would ever reach for normally.
>Obviously harder to expose a bright screen without some ND since the shutter speed is the phone's main exposure control

#114Firefox on Android seems to just be a static image, I can't see any text.
Probably the result of canvas fingerprinting protection configured in your `about:config`? With a default profile it seems to work fine on Firefox for Android.
Looks like I consistently get just the static image when I open in a new tab then switch to it, but then if I refresh the page without switching tabs it'll show the animation.

#115Neat! I've seen stuff like this that works as a magic eye thing. So you cross your eyes (or make them parallel, depending on the type of image) and it makes a 3d animation appear in front of the page.

#117If anybody implements that to antiscrenshot some sensitive data, somebody else will use another phone, a tablet or a camera to record a video of it. Nice idea though.
While a screencap image hides the message, a screencap video shows it perfectly well.

But then that would be a video, not a screenshot

#119I feel like there’s an ethical issue. If something is on my screen I own it. I know the law doesn’t agree but it feels right to me.

#120Ultimately people will just take photos of the screen. Seems like you’re just annoying people. I feel like there’s an ethical issue. If something is on my screen I own it. I know the law doesn’t agree but it feels right to me.
