The Light L16 – a multi-aperture computational camera
light.co
light.co
If only this was front and center on their webpage (it took me a really long time to find this):
"With 16 individual cameras, 10 of them firing simultaneously, the L16 captures the detail of your shot at multiple fixed focal lengths. Then the images are computationally fused to create an incredible high-quality final image with up to 52 megapixel resolution."
So you can fit a camera with the power of a DSLR in your pocket now, while having the same ease of use as a smart phone?
As a quick fix: drop the video and fix your site so that you can explain why your camera is so special at the top of the page. Use the image gallery as quick proof right after the explanation.
Many questions remain unanswered. Will I be able to fully edit the photos on my phone, or do I need to get a Mac and some custom software to really take advantage of this system? Will the software on the device be open? I'd like insurance against the unfortunate case that you make a nice device but then go out of business. Will the battery be replaceable? A non-replaceable battery in a $1600 handheld device is a really nasty design decision.
In short, really nice, and I would love to drop $200 right now to reserve one, but I'm afraid that I won't be able to undo the reservation if it turns out that the feature set of the phone doesn't match up with my practical needs. Marketing: you are losing sales right now. Go back to the beginning and explain to us why this is a good device.
This should come first.
And will I be able to replace the battery? ;)
Personally I'm completely turned off by the cellphone form factor, its possibly the worst possible way to hold something steady to take a photograph.
I had an interesting reaction reading this: I'm totally sold on the idea and science behind this. We have large scale radio telescopes, why not cameras?
But, I'm super turned off by the proposed plan: modified android OS combined with the promo photos makes me think viewfinder lag is going to be a bitch. v1 seems likely to feel like a janky short-run phone from a new manufacturer. Which is too bad, because the concept and possibilities are amazing.
Light; the articles mentioned a partnership with FoxConn; why not work with them or Samsung to put one out that you just license tech for?
And, it would be cool to see some high res samples.
Light is fusing (at capture time I think) a few normal-sized sensors each using different exposure duration, focal length, etc.
On the other hand Lytro collects a lot of tiny images each at the same exposure duration and focal length, but very close to each other. It's like having very big pixels but for each pixel you retain the color response from a large number of directions, instead of just the average color for that particular pixel, as in a regular camera.
Continuous refocusing can be performed after the fact in a Lytro, not possible (or very limited) with the Light. But the Light should be able to do native HDR in one take (and real time HDR video maybe), not possible with a Lytro.
Pretty impressive.
It is HDR. Multiple exposures means you can capture the full dynamic range in one "shot" and synthesize together the nicely exposed parts of each image.
> I'm curious how much post-processing went into each of these.
I mean, a bunch, but the camera's firmware is doing it. I'm sure typical punch up postprocessing happened for publication, still the interesting dynamic range stuff is happening in the camera.
How most people end up shooting HDR, however, the component images mostly all have full detail in the shadows and highlights, meaning the final image really not much more than you've described. You can do that with a single shot and a contrast slider.
all promotional photos anywhere are carefully photoshopped anyway.
Also I see extreme amounts of noise even though it's downsampled to 1920 on the long side, especially in the black guys shirt. There seems to be lots of lost detail and and also loss of information in the shadows. Of course it would help to have full res images to say something substantial, but it doesn't look all that promising to me.
I was a little disappointed in the amount of noise and the noise reduction in this pic until I started thinking about how it would look with other cameras. Probably a blurry, noisy mess with cellphone or compacts. To get the same effect as this pic with a DSLR, you'd have to massively stop down that 50mm lens and would end up boosting the ISO so high that even a modern full-frame DSLR wouldn't be that much better.
But that's actually not the most important part.
The most important part is that there are only two cameras in my life: my "good" camera and my smartphone, aka the camera I use when I know I'm going to be taking photos, and the camera I have on me all the time.
Since this image is probably boosted and noise reduced and photoshopped to make it the most presentable representation of the product, I really think the same amount of effort would get you better results, for less money, out of a DSLR. If you're into spending money, the right DSLR and lens combo would get you far, far better results.
On the other hand, yes, DSLRs are bulky and you don't want to carry them everywhere. But the Light is not a smartphone, so it's yet another device to have to remember and carry around, so while it's smaller, I'm still likely to leave it home because I just don't think to bring cameras with me everywhere. I've got an older smartphone (Galaxy Note 3) that can take photos pretty near this quality in its fakey HDR mode. I've seen some shots out of the newest iPhone that very much rival this sort of photo. And that iPhone is cheaper than the Light, plus it's not an extra device.
the advantage here is that the HDR frames can (presumably) be captured simultaneously, reducing motion blur
plus they seem to suggest some Lytro style ability to change the focus/depth of field after taking the photo
I see noise even at this resolution. I also see really bad highlight clipping (the "hitting a wall" type of clipping) and purple fringing like color shifts in the transparent plastic right above the vinyl.
To see something interesting, take a look at the gray box in the lower left corner. In the absolute corner there's "increased resolution", and then to the right of this there's a sharp line where a more smudged area takes over. And no, that is not beacause of shallow DOF.
Yes, supposedly it outputs (or will output) raw/mosaiced DNGs[1]. I think it will be some time before we'll have access to these though. There's about a year until release and even the files available (downsampled to 1920 on the long side) looks noisy and a bit smeared (probably from noise reduction).

Personally I think the money shot is the synthetic DoF simulation on the skater:

The subject isolation properties is a pretty big reason why people still bother with large-sensor cameras. As an amaterur, I don't have big demands for image quality, so I only bring my D60 or F4 when I want subject isolation. Otherwise I'm pretty happy with my smartphone as a camera (Lumia 930).
checkout the white outline around the knight, it has a halo. Then the fuzzy bokeh looks stepped somehow.
I'm guessing these sensors are way smaller than m43 even, so that f/1.2 won't produce anything near the stunning bokeh it would on a full-frame camera.
Because a lot of work has been done into making very good sensors and optics for phones, this approach does make some sense. It also lets you have more sensor surface area without the bulky optics. I'm pretty sure that there are telescope arrays that work in a similar way.
I'm not about to replace my cameras with these, but it's got potential.
There's more information in http://www.theverge.com/2015/10/7/9473793/light-l16-16-lens-... and http://www.technologyreview.com/news/542121/a-high-end-camer... .
You're right, that's like no lens blur I've ever seen.
Because even if you have a bunch of small sensors combined with software, they will still be noisy, and low light performance will be bad if they are standard small sensors
For instance, I wouldn't ditch my dSLR for this - http://light.co/content/2-gallery/gallery_modal_02.jpg
However, it's impossible to put larger sensors in thin phones because of the size of the optics, so putting a few small sensors and doing magic in software is a way to overcome this. I can believe that we'll be seeing this technology coming to phones in the not to distant future.
Aside from that, this is a really cool idea! But I don't know how it's being positioned. Is it a point and shoot replacement? Or a mirrorless camera replacement?
Or maybe it's just a technology demonstrator - this sort of system, suitably minimized, would make an excellent smartphone camera.
The Verge's review does say that it compares well with the 5DIII in detail. It also says that the Light's photos "weren't as punchy" -- not sure what that means. Saturation or contrast? I'll wait on a good comparison review.
It's not even a pre-order price. It's a crowdfunding contribution, for which the company is not obliged to give you anything in return.
> The company will take preorders, with a limited number of units available for $1,299, until Nov. 6.
The reservation form on the actual site is the same way. Why do you call it crowdfunding?

...or perhaps I'm letting my understanding of computer vision/geometry/linear algebra run away from me...
In any case, yeah don't google it.
Professionals don't care about the bulkiness of their cameras, they care about the performance and flexibility. DSLRs have 20+ years of development in terms of speed, durability, flexibility and the raw image processing power that the giants have spent decades perfecting (lots of work on DSPs).
How many pictures can it take in burst mode? How long does the battery last? Can I use my suite of existing lenses with this?
Sorry to say this camera, while unique and technical marvel, has an uphill battle from the business perspective. It's interesting from a niche perspective but I don't see it becoming a huge success financially for them, which is unfortunate because many talented people probably worked on this.
Forget a raw file format (that you will be able to use in LR/PS) and the flexibility and editing headroom it gives you. Perhaps there will be some specialist proprietary software like for the Lytro (that will be unsupported in 10 years, leaving you with unusable files). Considering this I really hope, as The Verge article says, "the output isn't as punchy" (which normally means contrasty and saturated).
The lack of a raw file format will also mean that I can forget DCP camera profiles to normalize the output with my other cameras.
What we know nothing about: what will AF be like? What will the dynamic range be like (considering they're stitching, not stacking, smartphone sensors)? Noise will probably be OK as you can downsample. But Sony is and Canon has 42/49 MP FF cameras out that doesn't need downsampling to look good. A year from now (when Light comes out) more cameras will have followed.
Focal length range is a bit strange. 35mm equiv is a bit on the long side to be an all-round solution. 24-70 would have been OK for me, but I realize that's personal.
Perhaps we shouldn't expect the death of the MILC/DSLR because of this camera just yet. Many hobbyist though, has left both the compact and the MILC/DSLR for a more enjoyable smartphone experience. Perhaps it could lure them back to buying a camera (without a phone in it)
I believe they are doing quite a bit of stacking, as they say they are processing up to 130 megapixels from 10 sensors to get the final image. There should definitely be a dynamic range improvement. I hope they can somehow apply their processing to video streams and provide a wide dynamic range (maybe even HDR) video, but I'd be surprised if they can do more than provide a cellphone-like 4K stream from a single sensor.
Focus speed shouldn't be an issue. I'm guessing it's using tiny cellphone-sized camera sensors, so even at the f/2.4 printed around the lens, they'll have massive depth of field. It looks like they even have the DOF printed on each lens: 10cm-infinity for the 35mm lenses, 40cm-inf for the 70mm, and 100cm-inf for the 150mm. Any focusing will be done computationally at post-processing time.
I'm interested in the concept; I just hope they're a little more developer-friendly then Lytro turned out to be. I know there's a lot of proprietary secret sauce going on with the computational post-processing, but if they can open up their system just a bit to let the crowd in to poke around, there's probably a lot of unique creative opportunities.
> Any focusing will be done computationally at post-processing time.
I catch myself being stuck in old ways of thinking. Again you are right and you just threw some fuel on my excitement fire.
I must say I love the innovation that new actors are bringing to the market. However, I will remain a bit skeptical until release. A lot can happen in a year.
It seems like a straight-forward problem to solve. I doubt putting 16 different cameras next to each other is something we'll see in smartphones anytime soon but looking at the results (especially low-light shots) is impressive.
Shame about the price, though. Honestly, I'd rather get a great Nikon for half. I guess we're a few years away from this having a chance in the mainstream.
1. Its a different take on the problem, stitching multiple lens and sensor data to make a whole that's better than the parts. Even if this don't work I think that idea would probably live to see another day.
2. There are comments about DSLR being fast, viewfinder easier to work on all situations and I agree to all of that. But I think the biggest point is what one of the founder said in the video, it doesn't matter if you have the best camera @home. This is something you can carry just like your smartphone.
3. Yet even this is a separate device, what I would like eventually is for this idea to be improved and implemented for smartphones. Maybe a 3 lens system that's not as good but much better than current cameras?
4. And I really loved the way the lenses were placed horizontally. That looks to be a simple yet effective innovation (not that I know if it has bad optical consequence).
I've seen the idea discussed a few times in the past, essentially doing for cameras what is done with multiple radio telescopes to create something that would be impractical to achieve with a single unit. This is the first time I've heard about someone having implemented the idea outside of a proof-of-concept. I'd be interested to see how well it works in practice. I'm not that much much of a photo taker myself, but a few of my friends are camera bugs so I'll be passing the link on for them to dissect.
It's hard to imagine this replacing my DSLR. If the cost is low enough it could replace my point and shoot though... I'm still more likely to have my phone on me than a camera...
Seems like this was spawned from a moment of inquiry where someone was so preoccupied with whether they could that no one stopped to think about whether they should.
So, good low-light capability in a box about the size of a smartphone plus high-quality high-resolution images.
If all the sensor pixel data was aligned it could create bias between the edge of the pixel and the center.
Edit: another thought is triangulation for determining depth
Also, better processors should allow more sampling from sensors and aggregating that info for better photos.

It's about time someone did this for consumer products.
