What parts of the spectrum do electronic cameras pick up?
The other day I was taking a photo of my hob (an induction hob that glows red to show it's on), and the entire image was oversaturated because my phone's camera was (I'm guessing) picking up some non-visible light.
Can anyone think of any other examples of this? Because it's kinda neat.Hi, I'm back, I guess. ^_^I cosplay and stream LPs of single player games on Twitch! Mon, Wed & Fri; currently playing: Nier: Replicant (Mon/Wed) and The Legend of Zelda: Oracle of Seasons (Thurs or Fri)

Common camera sensors can pick up UV to a certain extent and infrared light. Infrared photography is even its very own thing.

Re: What parts of the spectrum do electronic cameras pick up?
Yeah, I've done that with my phone camera, and you can see the light on the remote control blinking through the phone camera even though you can't see it directly. Most stuff outside the visible spectrum gets blocked by the glass used in camera lenses, though, which is why you need to get specially built ones in order to view stuff in the far infrared or ultra-violet.

I wonder what materials they use for lenses. For some scientific instruments they have lens covers and container windows that are transparent to the wavelengths they are looking for, but completely opaque for visible light.

No camera we have created can see the entire electromagnetic spectrum. We have different types of cameras that can cover just about the entire spectrum, but each type of camera only covers a set range of the spectrum.

And some of them are not very camera like. For example, the Very Large Array is a camera for radio waves (well, microwaves), but it doesn't have a nice array of pixels anywhere in its signal path. In fact, up until the data gets turned into a picture, it looks like nothing special.

Re: What parts of the spectrum do electronic cameras pick up?
I meant more like "have to go out of your way to find and own". A lot of specialised things cost the same as their more general counterparts (or don't cost a lot when the alternative is "nothing"), but you just won't get them unless you need them.
