also, something no one bothers pointing out - atleast it's the case with first two generations of iphone - taking a photo with the volume button causes the user to move the camera and results in an out-of-focus image. I can't imagine the autofocus re-focuses fast enough to resolve this issue in later generation iphones.
On the plus though, for the developer, advertising the feature certainly helps drive sales; as does "negative" press on Wired like this :)
- Zak 16y agoHow does pressing the volume button move the camera more than using the touchscreen? I've always considered the lack of a physical camera button on the iPhone to be a UX flaw.
- glhaynes 16y agoBecause more force is required (and thus more movement) to press down a button than to brush against the touchscreen, in theory at least. But yeah I'd like to have a physical camera button. I'd imagine it'd be best if it wasn't as stiff as the iPhone 4's volume control buttons.
- Tyrant505 16y agoSince this is not a serious camera, why not a small delay on capture so the movement has ended?
- glhaynes 16y agoI'm guessing that'd be more annoying than helpful, but it'd be interesting to try. If it were timed exactly right it could maybe work. It's not a serious camera in the sense that I wouldn't take one to do a magazine shoot, but lots of people take really good photos with phone cameras these days, they've come a long way.
- Tyrant505 16y agoThe best camera is of course the one you have with you. People have taken amazing photos with the iphone for sure! However, action shots are not likely among those unless in some abstract form.
- Someone 16y agoIf flash is off, the better thing is to just record video, and grab a picture from the moment the user likely started pressing the button. If flash is on, advanced software could combine the before-movement non-flash image with the flashed image, but I think that (currently) is too computationally expensive expensive for a mobile device.
- sukuriant 16y agoIs that force sufficient to truly affect the capture of an image with as low a focal length as the iPhone has? I was going to say that using the volume buttons permits the user to hold the phone in a proper camera stance (hand underneath the base to improve stability, no elbows out), but having just held an iPhone 4.0, I saw where the camera is placed and where the volume button is relative it, and how to properly hold the phone. It does not seem like the volume button is in the right spot for where the camera is to even use it like a proper camera. You're going to have to hold the phone weird to take a picture without your finger in the way to use the volume button as a shutter. tl;dr. The volume button isn't even in the right spot to use it as a shutter, and I wager pressing the volume button doesn't have any true advantage. For a phone that has a shutter button in what I perceive as the correct location, see the original Motorola Droid.
- nitrogen 16y agoIt's probably not the autofocus that's the issue, but rather the blur caused by the motion induced by pressing the button.
- blhack 16y agoHow is this different than the phycial shutter release button on my Nikon?
- jrockway 16y agoI am not a professional photographer, but when I take pictures where motion blur is going to be noticeable, I use the timer. That way, I can be not touching the camera when the shutter opens. (In the old days there were cable releases, but I haven't seen one of those since... 1990?)
- blhack 16y agoI use an IR trigger and a tripod :). iPhone has a timer though (at least on camera+). I'd day jiggle induced by pressing the volume button is a non issue. In fact, on the next iPhone I would love to see this as a default behavior.
- jrockway 16y agoYeah, I agree. I don't think the volume button is going to be an issue. I have tried to take pictures with my touchscreen Android phone before. Pretty bad. I blame myself rather than the phone. Also, I have never had a camera with an IR trigger. Want. :)
- lepht 16y agoYou could quite easily 'pre-load' the volume button before taking the photo by holding it down partially without actually engaging it. This would make the amount of remaining force necessary to actually snap the shot roughly comparable to that required for engaging a touch screen button. Sure, maybe your average user may not do this, but it would make the hardware shutter button a useful feature for the rest of us.
- edge17 16y agowhy the downvoting? I implemented this and did the experiments. That the photo blur is harder to control when you use the volume button to activate the shutter isn't my untested opinion.
- edge17 16y agoin addition, the iphone camera has a rolling shutter, not a physical shutter, so if the camera is not held still then motion issues are further exacerbated.
