There is no reason to do this. If you want to apply the algorithms and Iphone uses, simply take a burst and post process later for HDR or whatever. I remember being in middle school and messing around with Hugin and my Minolta bridge camera…
People value quick shots/edits and don’t care about quality or editing things later don’t mind an iPhone doing all this behind the scene - but it is irreversible. The sort of error in the article would drive myself and other photographers up the wall.
Also, an Iphone has a CPU and ISP that outclass desktops from only a few years ago - camera manufacturers simply don’t have the same compute available.
On the other hand, some brands do provide interesting computational photography in their cameras at the very high end. Panasonic mirrorless full frame cameras have a pixel shift mode for super res/no bayer interpolation, with some ability to fix motion between steps. Phase One has frame averaging and dual exposure in their IQ4 digital backs, for sequential capture into a single frame and super high dynamic range respectively.
- SSLy 4y ago>camera manufacturers simply don’t have the same compute available. what forbids them from buying the competitive SoCs from Qualcomm? Pride?
- scriptproof 4y agoThey would have to rewrite entirely their software. There had been some attemps to use these Qualcomm processors in cameras (the Yi M1 for example) and the result was terrible, the autofocus specially.
- _visgean 4y agoi think the battery consumption is also quite bad.
- zirgs 4y agoPower consumption is the main issue. Software bloat is another. Current digital cameras start up and are ready to shoot almost instantly. But it takes a while for a phone to boot up. Photographers don't want that.
- astrange 4y agoThe much larger sensors on a dedicated camera take longer to read out / have physical shutters / are very power hungry, so doing bursts is just a worse tradeoff on a dedicated camera than on a phone. Also, the camera market is much smaller than the phone market. Also, most camera companies are Japanese and Japanese companies are generally speaking not as good at software as they could be. (Though this is getting less true.)
- joking 4y agoThey don't really even have to do that, they could use the iPhone soc, but the pairing between the phone and the cameras it's not optimal.
- buildbot 4y agoHuge amounts of power and data - the power cost of sending 48MP over a PCB vs. over wifi is 12 orders of magnitude. 40pJ Vs . 2.5J !!!!
- astrange 4y agoThere is no consumer software that can do what the iPhone does with its sensors. iPhone HDR produces an HDR image file. Consumer HDR apps do the opposite - they take an HDR raw and tone map an sRGB JPEG out of it. The only portable format that really supports HDR images is EXR, so if you're not generating that you're not getting it. (I don't think there's anything that can do deep fusion either, though obviously you need it a lot less.)
- sorenjan 4y agoHugin produces exr files from image stacks.
- buildbot 4y agoSure, there’s not a photoshop button, but does github count https://github.com/timothybrooks/hdr-plus https://github.com/timothybrooks/hdr-plus It’s just an algorithm.
- aoeusnth1 4y agoCapture One creates .dng files, which are HDR raw equivalents when combining hdr from bracketed RAWs.
- illiac786 4y ago> iPhone HDR produces an HDR image file What file format is this? iPhone produces tone mapped HEIC, yes, but that’s not HDR as you pointed out. Or do you mean HDR video?
