I was quite impressed by this video[1] shot with an iPhone 4S, especially it's handling of motion/auto stabilisation. [1] http://vimeo.com/30578363 http://vimeo.com/30578363

This is pretty incredible, didn't realise how big of a jump there was. You can see that the 4 has a highly capable camera but the 4S is even better. I'm a 4S owner and can definitely see that it's better. Obviously you could say Camera+ want the iPhone camera to get better as their photos will be better and they'll sell more apps but at the same time it's impressive.

Amazing for sure.

  I do not know whether it is your sarcasm, your lack of sarcasm or, indeed, the lack of clarity with regards to any sarcasm that has offended people, but—I suspect that you would not have been down voted if you had used the word "Incredible". I did not find this article hard to believe; nor was it so-extraordinary-as-to-seem-impossible. While both reactions might have been experienced first-hand had it been shown to a pre-iPhone self, I have experienced this gradual revolution first hand—over a period of four years. These photographs were interesting and informative. The progression of camera quality and the extrapolation of future camera quality (that I found hard not to make) was Illuminating. I could not have drawn these conclusions had the site and the photographs not been totally credible.

As an iPhone 3G owner I feel about this photo just like how I feel about my iPhone: not surprised. 3GS was the phone that started opening doors.
- rane 15y ago
  This was my initial reaction but it appears 3G has fixed focus and thus is so much inferior to 3GS in the first pic.
nostromo 15y ago
The huge leap forward between 3G and 3Gs is mostly the addition of focus. Before 3GS, the iPhone camera was fixed focus. Taking a photo of something close up looked terrible, like the key does in the photo. I'm guessing they optimized the fixed focus to an object much further away from the camera.
- dpark 15y ago
  They optimized the focus for taking pictures of groups of people and landmarks, most likely, and neither of those tend to sit inches from the lens.
  - wisty 15y ago
    Yet they used an apature of f/2.8. Most phones have a high apature, so they focus on everything badly (landscape mode). The original iPhone has a lazer-sharp focus on everything a certain fixed distance away, and blurs everything else, but you can't actually set that distance. So you can get a few great shots (good for ads / PR), but most will be pretty crummy unless you get used to picking the right distance.
    - dpark 15y ago
      I'm guessing they took this in low light, so the phone opened up the aperture to compensate. (This also explains why one of the camera shots had ridiculous ISO.) I don't actually know for sure if the iPhone has an asjustable aperture, but I would assume so.
      - tsunamifury 15y ago
        Aperture measurements are relative to the lens/sensor. Most people don't understand this f2.8 on a cameraphone =/= f2.8 on an SLR =/= f2.8 on a Medium format camera.
        dpark 15y ago
        Aperture has nothing to do with the sensor. It's strictly a lens measurement. Sensor size affects the cost to build a lens with a given aperture (cheaper for smaller sensors, though that tends to balance out due to the difference in enlargement), but the sensor doesn't affect the actual aperture.

There's got to be some shenanigans going on when the iPhone 4s shot of the city looks better than the 5DMKII, an essentially $3000 camera.
- ben_straub 15y ago
  Not so shocking, actually. The 5D is a pro camera, and you're expected to pull the RAW data into Lightroom and manually tweak and tune the final product. Its output is optimized for this workflow: minimum processing in-camera, maximum options later. The iPhone's software, on the other hand, is doing some auto-adjustment before the file hits the SD card. It's optimized for a decent photo without any manual steps. Also, notice the distortion in the iPhone photo: the buildings "lean" towards each other. The Canon 24-70mm f/2.8 is a _nice_ piece of glass, and is worth every penny of its $1500 asking price. tl;dr: Take the 5D shot (in RAW, hopefully) and let a pro have a shot at it in Lightroom. That's a fair comparison.
  - wisty 15y ago
    Or blow up a small area (within the focus plane), and see which is sharper. Or better still, take a photo of a moving target at night. One advantage of a DSLR is that you can get a sharper photo with less light and a shorter exposure time. On web-sized photo, taken on a sunny day, you just can't see the difference. If you take a photo at night even a complete amateur like me can tell the difference. A DSLR isn't like a Ferrari, which blows the competition away in favorable conditions. It's like a Four wheel drive that can be used anywhere.
  - rbritton 15y ago
    The 5DII would have also been more accurately compared with the Canon EF 24mm f/1.4L II lens (according to the Exif data the sample photo was shot at 24mm). The iPhone 4S's camera is a fixed focal length while the Canon lens they used is a zoom lens. Zoom lenses trade certain attributes for the flexibility of being able to zoom, one of which is corner softness at wide open apertures. The 24-70 is a decent all-around lens, and I have used it extensively, but I have never encountered a zoom lens that reaches the same image quality as a fixed lens for the same focal length.
jerrya 15y ago
But really, there is no lens cover, and these things are shoved into a pocket with keys and coins and lint. How is it any phone can take good pictures (as to win contests, and our imaginations.) Why do so many (most) high end smartphones have no lens covers? It's the first think I would add to a smartphone I design, and yet, I am obviously completely wrong.
- jacobolus 15y ago
  You have to really damage the front of a lens to start noticeably degrading image quality. The nice thing about a lens is that for points in focus, light rays coming from the same direction hit the same spot on the sensor, regardless of which part of the front of the lens they pass through. See for example http://kurtmunger.com/dirty_lens_articleid35.html http://kurtmunger.com/dirty_lens_articleid35.html
  - jerrya 15y ago
    That was a terrific link and response, thank you. OTOH, the surface area of the lens he damaged is enormous compared to the tiny little lens on my phone....

  You win contests (with iphone photos) like Damon Winter did. http://lens.blogs.nytimes.com/2011/02/11/through-my-eye-not-hipstamatics/ http://lens.blogs.nytimes.com/2011/02/11/through-my-eye-not-... Connect with the subject (not necessarily emotionally) and portray things as you see them. Ie. it's not the tool that matters that much, it's the result/the content and how it speaks to us.
rplst8 15y ago
I see a lot of differences in hue/saturation between the S95/5D and the iPhone 4/4S. Reds are redder, blues are bluer. Over saturated images can definitely be pleasing, but typically are not natural. If the S95 was set to "Vivid" in the color settings, I think the result would be very similar to the iPhone 4/4S. The other interesting thing... According to the EXIF, the iPhone was shot with an ISO of 60. The S95 EXIF reports 20,480. That sounds strange to me... And possibly purposefully misleading.

This is a brilliant way to promote their app (cam plus) - a great blog post that adds value, and indirectly is used to promote their app while drawing traffic to their site. I should use that idea with promoting my apps!
BillPosters 15y ago
Looks like unsharp mask filter is automatically applied to 4s.. which is fine for happy snaps, but if DSLR cameras applied such sharpening automatically without the option to turn it off, just watch photographers around the world take to the streets in protest! So many images on the web are so over-sharpened by people who don't know how to sharpen properly or just use the default settings.
zwass 15y ago
An absurd comparison. The first series is comparing out of focus shots from older iPhones to in focus shots from newer iPhones. The last shot comparing the 5DMII makes the iPhone look better but this is because we are looking at small size photos that the iPhone by default sharpened and increased contrast and saturation on.
- nicksergeant 15y ago
  Not necessarily absurd. As mentioned in other comments here, the original iPhone had no focus. Objects close to the camera were naturally out of focus.
  - rorrr 15y ago
    With that "logic" they should compare it with 5D mk II and 1200mm lens shot in extremely low light at ISO 6400.
teflonhook 15y ago
Well that's the end of the camera industry.
- jseliger 15y ago
  1) Not really; see this discussion: http://news.ycombinator.com/item?id=3128316 http://news.ycombinator.com/item?id=3128316 . 2) A lot of people still aren't buying smart phones because they're really expensive. It looks like U.S. smartphone penetration in general is around 50%: http://www.google.com/search?q=smart+phone+penetration+united+states http://www.google.com/search?q=smart+phone+penetration+unite... , and most of them don't have cameras nearly this good and won't for a while. People who can afford a $50 – $200 pocket camera might not want to pay more than $100 a month for a smartphone data plan. 3) That being said, the smart money is definitely on the low-end pocket camera going away over time. 4) High-end cameras, even pocket ones (think the Canon S95 or S100 class) are going to be around for a long time. Ditto dSLRs. Until the laws of physics get violated, dSLRs are going to take vastly better pictures than camera phones. Which doesn't matter to most people but does to a substantial minority.

    The end of the camera industry != no cameras, it really means that standalone cameras are reduced to a niche market serving enthusiasts only. Will that happen? Seems likely, given current trends - phone cameras like the 4S are (nearly?) good enough now, I think.

Also, here is a neat video comparison between iphone 4s and Canon 5d MKII http://vimeo.com/30606785 http://vimeo.com/30606785 They used this little test rig (look at the size difference!) http://www.flickr.com/photos/67369108@N02/6248202568/in/photostream/lightbox/ http://www.flickr.com/photos/67369108@N02/6248202568/in/phot...

nlanier 15y ago
As a professional photographer, comparisons like this drive me absolutely insane, especially when they are called "incredible". Look, the iPhone 4s processes images with in-camera software and does it aggressively so images look pretty to the average user. They are over-saturated and over-sharpened. And the lack of detail captured by the small sensor all but negates the possibility of any REAL post processing. I get it. The consumer doesn't care. They just know the pictures look pretty. The practicing photographer knows better. The video comparisons are even more futile. The depth of field, flexibility, and low light performance of the 5D Mark II is so far beyond the iPhone 4s it makes my head spin. We are headed into exciting times when a device smaller than a deck of cards will replace a device the size of a toaster. I know. But we aren't there yet. Really, we aren't even close.
- zobzu 15y ago
  on the other hand everyone will tell you "its a phone not a DSLR its normal that it auto processes" then tell you "look its as good as the DSLR!" annoying ain't it :-) But most importantly, this comparison is just bad. The key picture is taken differently with different light and different settings even on the camera they're doing their best to hide the reality: a DSLR, even on all auto is far better than the 4S or any other phone, and its easy to see, on "regular" pictures, even for novices, the difference is huge.
- gbog 15y ago
  May I ask you, as a professional photographer, what do you think about the eruption of strong effects in photos shared with instagram. I fell like it is something fake, that it will look weird or stupid in a few months.
  - CWuestefeld 15y ago
    Butting in where I wasn't asked -- I think it's stupid, I don't use these in my Android. Artistic interpretation of images is great. But the display of a phone (especially a smaller display as on an iPhone) just doesn't let you do it effectively. Between the low resolution, and the fact that you're probably in an environment that makes it all but impossible to accurately judge contrast, sharpness, and color, the results are pretty much guaranteed to be garbage. If you want to do this kind of thing, go ahead. But to do so, put it on a real monitor so you can see what you're doing.
