Nikon Responds to Encryption Claims
ader writes "In a rare response to public complaints, Nikon has released a statement clarifying the use of encrypted white balance information in the NEF raw data from its digital cameras. They point out that this 'proprietary' format is accessible through the use of their 'proprietary' SDK, which is freely available to 'bona fide software companies' on written application. In other words: open source coders can butt out."
An OS project coder could be a bona - fide developer - nothing says Nikon wouldn't provide one to an OS project.
I'm a consultant - I convert gibberish into cash-flow.
This has been / is being discussed quite a lot on various Nikon-related boards. Unfortunately, Nikon is one of the least consumer-responsive companies I've ever come acrosss, to the point where even "Nikon Pros" - pros who exclusively use Nikon gear and evangelize for the company for free - are often not heard by the company leadership.
Unfortunately, this would seem to suggest that Nikon will be even less willing to listen to open source developers...unless they're loud enough to raise a stink in the mainstream media to some extent. Nikon's announcement about this issue is proof that bad publicity gets their attention...let's hope that there's enough volume to the (well reasoned, intelligent) complaints from the open source community.
I know I'd rather have some options when it comes to software. I use Nikon's commercial software, Nikon Capture, and it's very, very good...but competition is always a good thing.
No gods, no demons, and no masters. Secular Humanism!
TIFF isn't necessarily compressed, but it's not as good as raw. Raw is before de-mosaicing, before white balance, etc. It is the "raw" signal returned from the CCD or CMOS. (I imagine that's not entirely true, but it's close). And because Raw is only one value per pixel instead of 3, they tend to be much smaller than 16 bit tiffs.
Why are they doing the proprietary bit in the first place? Wouldn't they want their product to be as widely useable as possible?
Widely used by photographers and graphic artists, but not widely used by Kodak and other competing camera manufacturers.
happens already in the nikon kit aimed at law enforcement..
It is interesting with companies like AMD, Nvidia or HP Printers etc who have made competitive advantage out of catering (to some extent at least) to GNU/Linux/BSD and other ubergeeks. I suspect the average person who supports Free Software buys way more than the average amount of hardware and gadgets. We also read things like this and vote with our feet. At some point the balance will swing enough to make a real difference to the profit line - if we are not at that point already. The days of begging for drivers are past; the time of punishment for lazy manufacturers has begun. Seems no-one told Nikon to flee from the coming wrath..

oh... wrong Nikon, sorry.
So, somebody explain this to me. What am I missing here?
DMCA prevents the creation or distribution of a tool that defeats access control measures for the purpose of gaining unauthorized access to protected content.
Or something like that.
The white balance information is part of the image data. It's unique to each photo. It's the data that's created when the photographer takes the photo.
The person who will be gain access via a white balance plugin is the person who has the raw image data--typically the photographer, unless he gives the file to someone else.
The photographer can hardly be accused of using such a tool to gain access outside of his rights.
Further, since the tool is freely available to any "bona fide software developer" for the asking, it can hardly be described as an access control measure.
In short, it's the photographer's freakin' creation. Who the hell is Nikon or anybody else to say what he can or cannot do what he produced?

Yeah! That's how we took down Microsoft!!
"Derp de derp."
Reverse engineer the software (almost) anywhere in the world except the US, and everyone's happy. Also, place some text: "US citizens may not download", which no-one will notice. Not to mention that Nikon in this case encrypts data generated by me and the subject I take a picture of, it is my data being input through the lens. I get the data back in digital form, except I cannot access it with the tool I need to access it with. Does the DMCA allow me to reverse-engineer the encryption in order achieve interoperability? I'm told it does. So tell me, where's the problem?
FUD!
Stop spreading the FUD!
True confidence comes not from realising you are as good as your peers, but that your peers are as bad as you are.
>The number one reason for RAW formats is that
.
>people feel more 'elite' when they used them, and
>purchase the associated large storage media, etc.
Um . . . that's bullshit. Do people who use manual exposure and manual focus do it to feel elite too? That'd make about as much sense.
Here's two big advantages to using the RAW format:
1) You don't have to deal with the camera's attempts to auto-adjust the picture to make it look better (auto-sharpening, auto-contrast, auto-white balance, etc). You have significantly more control over the way the finished picture turns out if you shoot in RAW.
2) RAW gives you a lot of extra latitude in exposure, which is particularly handy since digital sensors are less forgiving of under/over-exposure than 35mm film.
Maybe YOU should take the time to learn the benefits of RAW before throwing attitude . .

A new website has launched to advocate for the public documentation of the manufacturer's raw format spec's. From the website "We want camera manufacturers to publicly document their RAW image formats -- past, present, and future. The goal of OpenRAW is to encourage image preservation and give creative choice of how images are processed to the creators of the images. To this end, we advocate open documentation of information about the how the raw data is stored and the camera settings selected by the photographer."
At present, the only documented RAW format is Adobe's Digital Negative (DNG). The current problem is that I dont think it's ever actually been implemented in an actual camera. Adobe provides a free converter, which is great, but it's not the same thing.
Personally, I'd like adobe's solution. A single format is easier for developers to work with than the ever growing list of RAW formats (even if they are open). It's this thing called standards.
A format is not "property". Does Nikon own the pictures I take with my camera? No? Then why the hell can't I read the white balance information in them?
My picture, my property. Ability to read my picture? Also belongs to me.
May not be the way it is right now, but it's the way it damn well should be.
Random and weird software I've written.
Nikon has both property and moral rights over their software.
But...do those "property and moral rights" extend to the photos that are taken by the person using the software? Does Nikon "own" the white-balance information of the picture taken by the photographer?
If so, Nikon is basically saying "Buy our camera and use it, but you don't own your pictures".
It'd be like (in film camera terms) buying Kodak film, taking pictures, an then Kodak telling you that you don't own the negative.
This whole thing, including their response, is BULLSHIT.
The NEF format isn't proprietary. It's a TIFF file. The only thing "proprietary" about it is a handful of tags they use. Crack it open with a hex editor and see for yourself. The only trick in reading in the image data is that it is stored in a "sub-TIFF". So you read in all the regular tiff tags (width, height, color depth, etc.), read in the the sub-tiff (easy enough to find, I don't remember the exact tag number), and you can display NEFs.
As far as white balance information goes, that is not atrade secret. It's not an algorithm, it's not code, it's not executable. It is data. More to the point, it is YOUR data.
I could give a rat's ass about their METHOD for obtaining white balance information. But having the white balance data tells you nothing about how they obtained it. It is just data.
Not only that, but white balance data is essential for all digital cameras for correct image reproduction. All digital cameras (including web cams), obtain white balance information either from the user or the environment via whatever algorithms the manufacturers decide on.
There is nothing, NOTHING, special about white balance data in a raw file. There is absolutely no reason this data needs to be encrypted. There is nothing to protect. It would be like Nikon saying they encrypt the image data to prevent someone figuring out what algorithms they use to process the CCD data.
The only fathomable reason for this nonsense is profit, plain and simple. Now that they've been called on it, they're trying the PR spin machine to make it sound like they're trying to help.
And as far as the SDK goes, good luck getting it. They apparently don't like independant developers (such as myself) writing programs for their cameras. So unless your part of a recogonized bona-fide software developer COMPANY, you're not going to get the SDK.
So that leaves those of us interested in such programming to reverse-engineer (which I've done so I could access the tone curves inside their curve files).
First, I found that Nikon was misleading about the compressed NEF files (they are supposed to be lossless raw data, but they're not). Then I found that they were also misleading about how the raw files were produced (raw files are suppose to contain the straight CCD sensor data, but Nikon applies a median filter to the data before it is saved). Sort of pissed me off because I do astrophotography and the filter wipes out stars and other features. And now, they're trying to pull this vomitous crap.
I sincerely hope nobody believes this, but sadly I think many will.
