    Are LED and CFL lights harmful to your eyes? Over the past few months I have developed an intolerance to LED and CFL lighting of any kind, and when I asked the optometrist and opthamologist, they said that LEDs and CFLs emit a harmful spectrum of blue light that has been scientifically proven to cause damage to human eyes. My question is, How are they still in the market? Nearly everyone is using LED lights in their house and in all buildings, now to the point that incandescent bulbs might soon go extinct. How are LEDs still in the market? Are incandescents really going extinct? (I've used incandescent bulbs my whole life and never had a problem. Even before I knew about this harmful spectrum of blue light, there was something about LEDs and CFLs that made me uncomfortable)

  • Why don't pay phones exist anymore?

    Best answer: They're still around in some places, but they are increasingly rare. The main issue is that potentially useful they may be, but they aren't economically viable these days. Nowadays every man and his dog has a cell phone so there's simply not that much incentive to use a pay phone anymore. As such, the... show more
    Best answer: They're still around in some places, but they are increasingly rare.

    The main issue is that potentially useful they may be, but they aren't economically viable these days. Nowadays every man and his dog has a cell phone so there's simply not that much incentive to use a pay phone anymore. As such, the amount of money pay phones generate has plummeted, and in many places it simply costs more money to maintain and operate them than they actually bring in.

    I m going to Japan on September. We re going from LAX a one stop to china PEK airport and arriving to Narita airport. I tried looking at their website but couldn t find any answers on Camera regulations. I Have a canon Rebel t6 it has a portable charger. I know I have to put it on the carry on bag with the lens detached from the camera. Is it going to be an issue? Are they going to ask me to remove the camera? I m going to give them a call to make sure.

  • Can I record a cd onto a Cassette Tape?

    Best answer: You can't "download" anything onto a cassette but you can record any kind of audio at all onto cassette but it has to be done in "real time". I don't know what "RHCP" CDs are but if they're audio CDs then you can revord them onto cassette whilst they're playing. If... show more

    I don't know what "RHCP" CDs are but if they're audio CDs then you can revord them onto cassette whilst they're playing.

    If you have the CDs and a player though, why on earth would you want cassette copies? No offence, but that's a terrible idea.

  • What's "time-lapse" camera or video mean?

    Best answer: It means "compressing time"... like capturing images or video over hours, days, weeks or months and producing a video playback that lasts seconds.

    Best answer: It means "compressing time"... like capturing images or video over hours, days, weeks or months and producing a video playback that lasts seconds.

    Example: Year ago, I captured 8+ hours of the drive from San Diego, CA to San Francisco, CA. The final rendered project takes about 6 minutes to playback.

    There are at least two ways to do time lapse:
    1) Capture lots of video and use a video editor to spead it up, then render the project. In the case of my SD--> SF drive, I captured eight 60-minute miniDV tapes, imported all (in HD, that came to 44 gig per hour x 8 hours) of video ready to edit. I think I sped it up about 8,000%.

    2) Take LOTS of still images at a preset interval. In this case, a camera with an internal or external intervalometer makes it lots easier. We can use the SD--> SF trip as an example. Set the intervalometer to take 1 still image every minute. 60 minutes in an hour x 80 hours = 4,800 still images or "frames". Drop these, in order, on the video editor's timeline. If we assume 24 frames per second, then 4,800 divided by 24 frames per second = 200 second playback or 3.33 minutes.

    In each case, don't move the camera. Use a tripod or other steadying device. There are "time lapse motion control" devices available if you want to pan (horizontal) the camera. They move the image capture device slowly and evenly - when sped up, it looks like "normal" speed panning.
