Paragon8 posted:The iPhone 4 I think does in camera HDR already Conceptually it's simple. If current camera sensors are recording N levels of light intensity, all you have to do is make a sensor that can detect N+1.. presto, you have an HDR file. At that point the limiting factor is the levels of light intensity that our monitors can reproduce. Not that this would matter I suppose, as most photographers interpret HDR as an opportunity to drive color saturation through the roof, and you don't need a new monitor to do that.

You think apple actually spends money on engineering? what would they spend on advertising then? They probably just take 2 images with a cheap sensor to bracket and combine in software.

You can convert a raster file to a vector file through tracing and edge detection, but unless the image is something relatively simple on a clean background, it'll look like crap. Captain Postal posted:They probably just take 2 images with a cheap sensor to bracket and combine in software. I'm pretty sure they take one photo, boost the shadows, bring down the highlights and call it a day. The camera application works too fast for it to be doing real bracketing.

Yeah, you're probably both right. Much easier to do it in one shot. Out of curiosity though, how fast can a camera like that take images if there's no mirror and you don't need to wait for the last pixel to be read before reading the first one again? Is it just the response time of the photodiode (+buffering)? edit: If I worked for apple, I'd define 6bit as standard dynamic range (or whatever the iphone 4 display does). Much easier to get over the bar to be classified as HDR then, and most apple users would never realise they were being scammed.

So you can take pictures as fast as data comes in off the sensor and you can write it to permanent storage. Which, for the record, is not instant. There's a polling speed where the device reads each pixels in a row before doing the next row. Look up pictures of plane propellers taken by cell phones.. get some really neat distortions.

Is the bandwidth and speed is just not there for all data points to be saved at once off the sensor and written to storage, and instead being forced to be written one at a time, albeit ridiculously fast? And it's just CMOS sensors that have that issue, right? Do CCD sensors work the same way?

I was under the impression most cell phone cameras work similar to scanning backs, ie. they poll the sensor for the information instead of it coming in as a lump of data.

I'm not an engineer so in some ways I'm talking out my rear end here, but I think yes it comes down to the basic technology. A CCD has to be completely blocked from light prior to taking a picture, works just like film does. A CMOS can be "reset" via software so in theory you don't even need a mechanical shutter. CMOS sensors can have mechanical shutters, but I think most cellphones omit them to save space.

I'm left handed, and I don't have a problem at all with SLRs or other cameras built to be held in the right hand. Focus and zoom are with the left hand, and both hands work together to support the weight and fine-tune composition. I use a computer mouse right-handed, so I'm used to pushing buttons and rolling a wheel with the fingers of my right hand anyways. I don't think a mirror-image version would be any easier for me to use.

Mouses are especially common, and something like a camera doesn't take nearly the coordination that a mouse does to use in the other hand.

Being a lefty means that we all have to be somewhat ambidextrous. Cameras don't pose a problem for me any more than using a mouse, using chopsticks, or writing (though the last part is pretty drat ugly, but doable.) Unfortunately, having a dominant left eye means that it's a bit hard to shoot with both eyes open; I can't see the viewfinder out of the right eye without closing my left, but my right hand blocks off most of my vision if I hold the viewfinder to my left eye. Martytoof posted:I have a friend who is pretty much limited to Point and Shoots because he doesn't have a right arm. Too bad for him there's really no market for "people who actually NEED a left handed DSLR" Unfortunately, even if there were left-handed DSLRs he'd probably have a problem zooming in/out, unless there were a way to strap the DSLR onto his head. Hey, that could be an interesting invention, though I can't imagine who'd want to look like a cyborg with that. It'd be heavy as all hell, too.

You could hack together a grip from a remote shutter cable and a flash bracket. You wouldn't have many controls but it would be pretty cool to see a one armed man doing street with a custom left hand camera.

Everyone will be super jealous. (though seriously, that might actually work, if you got a camera with a remote that has a wheel for adjusting settings) Get a camera with a fold out display, and have someone good with electronics detach the screen so he can mount it on his wrist.

I shot (for free) an event for a good nonprofit organization and they told me that they were so kind as to let me keep the photos and I could even use them for my own promotion! Aren't they so nice. I kept my mouth shut of course, but that kind of attitude is pretty frustrating, especially since I did this on a favor to another photographer friend, and the moment I arrived, they began ordering me around ("you'll need to stay here and act like paparazzi so people feel special").
