Online Camera: Photos with a Self-Timer and Photo Booth

The viewfinder shows the video stream, which a camera delivers at a modest size so it can run smoothly. Chrome and Edge also let a page ask the camera for a still from its photo mode — on phones that is often 12 MP against about 2 MP of video. The tool uses the still when it really has more pixels and the same orientation, and maps the frame you composed onto it, so the photo shows exactly what you framed. The info line under the viewfinder says which size you will get.

A web page only gets the controls the browser passes on from the camera driver. Chrome and Edge pass exposure, focus, white balance and zoom for most Android phones and for many webcams; Firefox and Safari pass none. The manual panel therefore shows only what your camera reported and lists the rest as missing — a slider that does nothing would be worse than no slider.

No, by default the file is saved the right way round, the way other people see you, while the front camera viewfinder is mirrored like a bathroom mirror so it is easy to pose. If you want the file to match the mirrored view, turn on “Save photos mirrored” in the Camera section. Text in the background reads correctly only in the unmirrored photo.

The strip is made at 300 dpi: 600×1800 px for a 2×6″ strip and 1200×1800 px for two strips on a 10×15 cm (4×6″) print. Press “Print at real size” and choose 100% or “actual size” in the print dialog, or order a 10×15 print from the file and cut it along the dashed line into two strips.

They stay in this browser's storage for the site, so a reload or a closed tab does not lose them, and they are shown again in the roll. They are removed when you delete them in the roll or clear the site data in the browser. In a private window the browser may keep nothing between visits — the tool then says so above the roll, and it is better to download the photos before closing the tab.

Yes: the interval clock runs in a background worker, which browsers do not slow down the way they slow page timers, and the screen is kept on. Closing the tab, locking the phone or putting the laptop to sleep stops it. For long sessions plug the device into power — at one frame every 5 seconds an hour gives 720 frames, 30 seconds of video at 24 fps.
