We've been wondering what that second camera on the back of the HTC M8 (a.k.a. "The All New HTC One") was all about since the first leaks arrived. If an Australian Telstra ad for the new device is to be believed, it is indeed intended to bolster the phone's low-light shooting performance. The advertisement spotted by GSMArena reveals a few things that we didn't already know, and it does indicate that the "Duo Camera" can "create vivid images even in low light."


Low light photography is always tricky, and it's particularly difficult on mobile cameras thanks to their generally small sensors and lenses. This is just a guess, but I'm assuming that the secondary camera on the top portion of the M8 has a much lower F-stop value than the primary one, which might be able to create better low-light photos when combined with shots from the main camera with HDR-style software. The double LED flash module, which appears to use two different colors of light, might be part of that as well. The ad also says that you'll be able to choose where to focus and soften the background, plus add dual-camera 3D effects. HTC previously released a phone with two cameras specifically for the 3D feature, the EVO 3D, which also featured a 3D screen. There's no indication that the M8 will use that screen technology.

Other juicy bits: the Easy Access promotional text indicates that HTC's Sense 6.0 upgrade will allow users to double-tap a dormant phone to turn it on, much like LG's KnockOn feature. Telstra's price for the phone is $840 Australian dollars to buy it outright, which is comparable with other high-end phones in the Australian market. That would put it at the usual $600-700 USD price in America, with varying subsidies affecting on-contract prices.

HTC is expected to announce the new One, and possibly other hardware like a new One Mini, at its March 25th event in New York City and London.

    • Whyzor

      Bolder, it was too shy in the dark.

    A good 3D image will require that the two cameras are same

    • http://www.vrdwellersblog.com/ Miles Reiter

      Just optically yeah. But any two cameras allow for depth mapping algorithmically and that makes it a lot easier to create a good 3D effect in post. Like how they made Jurassic Park and Titanic 3D for a re-release, they had to go in and trace everything and manually assign depth, but if you already have a depth map you can automatically create a decent 3D image.

  • Good_Ole_Pinocchio

    It's just not about Low-Light looks like they're doing the same focus tricks the GS5 and others will be doing.

    "Duo Camera

    Create vivid images even in low light and professionally edit memories after you've taken the shot. Choose where to focus, highligh what you love, soften backgrounds and add 3D effects."

    • http://www.androidpolice.com/author/ron-amadeo/ Ron Amadeo

      I don't interpret it that way. There is a big difference between "blur" and "focus." The S5 lets you selectively blur things, like photoshop, but this ad claims to let you selectively focus things after the image is taken, like a (probably cheap imitation of a) Lytro.

      The difference being that if something is out of focus, post-capture blur on the S5 won't help, but post-capture focus on the One will.

      • Nathan Bryant

        They mention "focus" with S5 as well and there is a in depth video showing you how it works before you even take the picture. It's not a trick or just an effect.

        • http://www.androidpolice.com/author/ron-amadeo/ Ron Amadeo

          Oh ok, I played with a photoshopping blur tool on the GS5 and thought that was all it did.

          I just watched the video. It's kind of a trick. It works like HDR I think, where it takes a bunch of pictures one after another, just at different focal lengths instead of different exposures. This means it will be really slow—you'll have to stand still while it snaps a bunch of pictures—and most likely be a special mode that no one would turn on other than for a demo.

          If HTC's thing is what I think it is, it would be simultaneous, automatic, and baked into every picture. I still don't think it's useful or anything, just different.

      • Cory_S

        The S5 takes pictures at different focal points, 5 I believe, and then lets you choose which region to focus on.

  • Guest

    U DON'T SAY?

  • Detonation

    I'd say the ability to choose your focus after the shot was taken is more headline worthy than improving low light performance

    • Nathan Bryant

      True, but you don't need two cameras to do that. Unless HTC really wants to reinvent things to be unique

      • redsnowfox

        Neither is dual camera setup a necessity to improve low light performance.

        • etherspin

          it is if you don't want to also limit the MP output unnecessarily for well lit photos. this sounds good and was what I was waiting to hear. So many cameras on android phones have abysmal low light performance, the original One can do lowlight but makes for mediocre prints and images that look bad on high resolution monitors and tablets

      • PG Man

        If you knew HTC like myself for example, you'd know HTC doesn't try to be unique lol, they just are and most importantly, they don't put gimmicks on their devices ;)

    • imlip

      a lot of people would beg to differ.

  • Sean Lumly

    Dual cameras should open the door for some very interesting computational photography possibilities. With clever algorithms and differentiated optics, things like non-digital zoom, accurate denoising, depthmap generation, focus after shot, better low-light photos, simulated bokeh, 3D photos, better de-bluring, digital stabilization, etc, should all be possible.

    It's interesting how effectively mobile cameras are compensating for a clear optics disadvantage compared to much more expensive professional cameras, and I wouldn't be surprised if they begin to out-perform them as well.

    • PG Man

      ...mmmmm....an HTC with Adaptive Optics tech, take Zoe's of galactic centre and the black hole with its ultra low light sensor, gimme gimme HTC you can do it, it's not their tech but like CHER (huh?), she don't write no songs but when she sings them they are hers, sorry, she came up on tv. Way off...

  • HellG

    Great coverage Michael,One small thing though,There was nothing special about the Evo 3D screen nor did it had any special ability to view 3D images without glasses.

    The built in app would just use the accelerometer to move the pictures as you tilt the phone to give you that 3D feeling that was the same for the lg optimus 3D.

    Apps that does the same functionality existed on iOS for example for years before any of these phones debuted,so if they are really going to have that ability the screen wont be an obstacle.

    • Nat Chan

      You can actually view 3D images on the Evo 3D screen without glasses.

    • Barnassey

      Did you even own the phone?

    • Evan Knofsky


      Go look at the display section, it was a special screen..

    • Anfronie

      I have the evo 3d ...it has a special screen that allows two separate images to be viewed by each eyeball respectively. This of course without needing glasses to view the 3d image. Neat technology that never really got super popular.

      • RhodBerth

        It got never popular b/c both the LG Optimus 3D and the HTC Evo 3D failed as cellphones. The LG phone at least was a great 3D experience. But people won't buy a 3D experience if the rest of the phone fails.

    • RhodBerth

      You are wrong. My Optimus 3D screen was a 3D screen, not a trick / tilted / accelerometer 3D screen.

      And I hope that the M8 will have a 3D screen as well, but I'm very happy with just a 3D camera as well. HTC is right to not advertise the 3D too much, people for silly reasons seem to dislike it, while it's awesome.

      I'm still enjoying my LG Optimus 3D photo's a lot on my 3D TV, and I'll buy this phone it if'll indeed support a 3D camera.

  • Gopal Bhaire

    $840 whoaaaa

    • Detonation

      Australian dollars

  • robert26101

    I don't believe any of these kind of leaks anymore. Not after the so called leaked packaging of the Galaxy S5 with a QHD screen and 3 gigs of ram and blah blah blah.

    • PG Man

      You have to get the fact that Samsung galaxy line IS just a hype, people dream on , and now get that HTC is/ has always surpassed expectations and rumours on top of all the cool leaks that always prove oh so on the dot, if you're not amazed by the new HTC, look closer, pause that 1080p video that weird boy posted, pause and check those edges, the thin black line curving the speakers.etc..man I love my ipad mini for spamming with my excitement for this One.

  • miri

    Was the codename M7 ever present in the original HTC One's advertising?

    • Brendan

      Yes, I believe so.

      • miri

        Figures. I've never actually seen an ad for the One anyway.

        • Brendan

          Really? I saw them everywhere for a while, especially right at launch.

  • Mark

    Misleading reporting...the ad does not say that the secondary camera is just for low light shooting it says create vivid images EVEN in low light. In other words the secondary camera improves overall image quality EVEN in low light.

  • http://www.facebook.com/profile.php?id=100003386080045 John doe

    Im wondering if one will be able to take parallax style photos straight from the camera right to the wallpaper. Sounds plausible.

  • Joe

    Good on you Telstra, Aussie Pride ;)

  • Anthony Johnson

    That’s cool! If this is true then there is no need to keep
    my digital camera to click the better photographs in low or dim light. I read
    somewhere that it is going to launch on around 24th March and their
    makers said that it will give tough competition to Galaxy S5. Well just wait
    for the date that will show that the commitment made by them meet up with the
    expectation or not. One phone I like the most under HTC series is its DNA which
    support wireless charging feature with nice configuration.

  • PG Man

    Ok people, hate to say told you so, for the past 10 years, HTC is the Smartphone King lol. I realized that fully after owning....look at my profile pic, that was 2008, here we go: highest LCDppi touchscreen in industry 640x480 in 2.8" that's 286 PPI, dual touch capacitive multi light scroll wheel and Click D-pad for games, "wheel" has 4 soft white xbox like glowing lights that do different sequences that only u and ur htc know, different for SMS, calls, voicemail, email, 3D sense UX overlaying WinMobile with 3d flip widgets of contacts, pix, weather, stuff Droid and iOS dont have built in today, it was the first front facing camera phone(known to NA), and built like a diamond with self retracting magnetic stylus that closed like a mercedes - worlds most adored/modded phone, of course today, 6 light years into mobile computing lead on everyone, of course the camera will give it all= depth of field, night shooting, refocusing, stereoscopic /3D effects, instant zoom...once again, EPPICC, I can't wait no more I got temp phones - LG and Samsung, fu both for screwing me, stop selling lies to people, that's what it's all about to me, tell the people you're selling lemons, yeah right. HTC will not be a starving artist if I can help it lol!....wow I'm crazy.

  • metin Alkacir


    everyone in the world 'such a super technical and favorite HTC. I would like to have a mobile.
