like we were all just getting used to phones with high resolution cameras on
them as a mundane trapping of everyday life when suddenly smartphones with not
one but two cameras started appearing
everywhere and although it may be surprising to learn that the first dual
camera smartphone showed up all the way back in 2011 they didn't experience an
explosion in popularity until recently but why well there is actual utility to
having more than one lens on the back of your smartphone unlike some other
marketing gimmicks that try to draw you in with larger and larger numbers so one
of the most common reasons for that second camera is to give the user
telephoto functionality and that is
basically exactly what it sounds like a telephoto lens allows the photographer
to zoom in on something that is further off in the distance you see although you
can probably like pinch to zoom on your
single lens smartphone it's actually all things what's really happening is that
the logic inside your phone is just enlarging whatever image was already
being picked up by the sensor this is called digital zoom and it basically
shouldn't be used at all just take the original photo and crop it
later if you need to it is pretty much the same thing so a telephoto lens with
a longer focal length can overcome this problem especially as it's difficult to
build lenses that can optical zoom that is to say they can be close in and far
away on the fly into a smartphone that
is unless you don't care about being able to carry it around in your pocket so this regular lens plus telephoto
setup is common on flagship phones such as the iPhone and Samsung Galaxy but
some manufacturers actually go the other way and include a wide-angle lens on the
secondary camera instead you can actually learn a lot more about wide-angle lenses up here but in a
nutshell instead of being built for getting a look at distant objects
wide-angle lenses allow you to take in more of a scene overall so it's great if
you want to get a dramatic photo of a valley or cityscape you know your
friends into a selfie or upload a pic of your apartment to Airbnb that makes it
look much more spacious than it actually is now still other phones put a
monochrome sensor into their second camera meaning but you can shoot in
black and white wait hold on what's the
point of that when it takes about two seconds to apply a filter that will
convert a color image to black and white ah yes well black and white sensors tend
to have better sensitivity to light than color ones meaning that they perform
better in low-light scenarios and can produce images with less noise now
although many modern smartphones allow you to use the monochrome camera on its
own to just take black and white photos what's more interesting is the fact that
these phones can take image data from the color sensor and the black and white
sensor and then combine them to make a sharper looking color image than what
you'd get with just the color sensor alone Huawei's current lineup is notable
for having this feature and this image combining functionality is not limited
to phones with monochrome cameras either other phones that have lenses of two
different focal lengths as we discussed can actually work them together to sense
depth allowing for a blurry background depth of field or bokeh effect to be
applied in software post-processing and while this effect is not as good as
you'd get with a larger standalone camera with a bigger sensor it can still
look pretty good in a pinch for a carry everywhere all the time device do keep
in mind though that through all of this there are trade-offs typically the
second camera no phone will be of lower quality and none of this functionality
makes your phone a substitute for a higher-end point-and-shoot or DSLR which
you can learn more about right up there even so it is cool to see smartphones
becoming more and more versatile when it comes to snapping photos especially if
you don't want to lug around bulky equipment in your quest to become
Instagram famous today's videos brought to you by the
