What is Night Mode? (& How It Makes Your Phone Take Much Better Photos in the Dark)

by birtanpublished on August 29, 2020

Night mode night sight bright night whatever you call it this contra mode now available on a ton of smart phones allows you to take photos in much darker environments while still getting an image that is very much usable when done but what exactly is night mode and what

Type of sorcery does a use to help your phone see in the dark well in this episode of decoder where I try to explain a new piece of technology each week let's dive into the tech behind night mode as well as how it can help

Your phone tape thanks to Squarespace for sponsoring today's episode we'll talk more about them in a bit but first the term night mode is a catch-all name for the feature most likely due to the fact that Huawei called it that when

They popularized it first on the p20 Pro where it's just called night in the camera modes other manufacturers had different names sometimes though Samsung on the iPhone both also call it night mode but LG calls it night view the

Pixel calls it night sight oneplus calls at night scape and even less expensive phones have it in some form or another like TCL plexes super night and the Nokia 7.2 s night mode etc now thanks to differences in the camera Hardware along

With the software each manufacturer is using they're not all created equally but the technology behind them is all roughly the same the way it works is that it's a modified version of a technology that we've had in phones for

A while now called HDR or high dynamic range imaging not to be confused with the HDR display technology that you hear about in TVs monitors Netflix has an icon for and the like as that's different maybe we'll do an episode on

That one day as well what HDR imaging and in turn night mode does though is it essentially takes a bunch of photos all of varying exposure levels exposure being the length of time the sensor is exposed to light with the

Shorter that time the darker the image and the longer the brighter after it has those images it uses software to determine the various parts of the image and what exposure each of those parts needs to be then it uses those chunks

Essentially from each of the images at different exposure levels to combine them all together to create a much more overall balanced image now depending on the phone and the software the manufacturer has created the amount of

Time for those longer exposure shots in this collection of images kymmie as long as 30 seconds and can either be manually set using the on-screen controls or is automatically decided by the phone based on the

Available light and its own algorithms the phone actually goes even a step beyond all this already impressive stuff by also having to compensate for something that long exposure photos really don't like movement whenever you

Take a long exposure shot any object or person that moves through the image will cause blurs or streaks through the image likewise if the camera itself moves even in the slightest way that will also cause streaks in blurs in the final

Image the longer the exposure the more pronounced those streaks and if you've ever seen light painting images or night sky shots like these on the internet they use extremely long exposure times in order to purposely capture those

Streaks for artistic reasons instead now the way manufacturers have gone around the nuisance of movement is by using their own clever AI algorithms while the image is being taken to negate these things so for people or objects moving

Through the image the software just identifies anything in the image that seems to move location within the shot over multiple frames and then it just tries to ignore that object and not put it in the final image to counteract the

Phone's movement the software can use the accelerometer in the phone along with the image itself to determine how shaky your hand is and then grab the same image over and over for the exposures and again line them up for the

Final photo now really quick what if you use this night mode and take a bunch of photos that you think look really great but you're not really sure where to display them well you could always make a website using Squarespace they've all

The tools you'll need to build any type of website including a photo portfolio of shots taken exclusively a night mode if that's your thing it's easy to use you can get your very own domain directly from them there's no coding

Required and they have professionally made templates to help your site stand out so head to the link below for a free trial and when you're ready to launch if you use that link you'll save 10% off your first purchase of a website or

Domain now guys night mode how it works etc now some manufacturers actually have taken this to even more extremes like Google with the pixel and it's a strobe mode but we won't get into that here if you do want to check out more

Information on that I'll leave a link to my buddy David of Mel's video over on Android authority you can click that link and check that out there you go hope you guys enjoyed that let me know in the comments

Below what you think of this video also if you guys have another topic you'd like to see me do code here on this show let me know about that in the comments as well if you like this video please thumbs up and share it greatly
