When i was little we had a webcam we had to buy separately which connected to our computer via USB, being the time (Early 2000's maybe at a guess 2003??) it was very bad quality, very blurry.
think this might actually be the same one we had^^ a "Logitech QuickCam Messenger WebCam" as quoted on Amazon
.
Usually webcams these days are included within laptops, mine doesn't seem to work? though that doesn't bother me as mine is always covered with a googly eye :)
Obviously computer cams are higher quality today as apposed to how they were last time i ever used one (2012ish).
The original sense of the term Webcam is basically a video camera connected to the Web continuously rather than one small session, which supplies a view for anyone viewing through a web page. Loads of online presences use them for live streaming for gaming(Twitch), Facebook, Instagram, sometimes Youtube etc. It has enabled the ability to use "web cams" as security cameras that can feed back to a computer or your mobile phone, traffic cameras etc.
Modern webcams also have the capability to capture pulse rate - accurate to +5 bpm.
Computer webcams aren't something that i generally use and i wish i could have taken my own photos using my webcam for this blog :( but after learning a wee bit more i think i'll come to think a bit more about different photography choices in any future photography experiments
