      I realize you were making a joke, but RAW isn't a single format. It is a generic term for dozens of different formats, each of which depends on the make and model of digital cameras. Even if you take just Canon, you've got several formats including at least CRW, TIFF (with an extended section containing the raw data), and CR2. Each of these formats supports several camera models which may or may not need to be taken into account when decoding.

    I'm not going to say I told you so, but I told you so. The minute you give up the physical artifact and rely on a digital representation of your data, you are at the risk of any company who wishes to exert some control over the format of that data. That's why all those RAW file formats for each camera are different from company to company. They gain the most benefit by locking you into a certain piece of software and forcing you along their upgrade path.

    If you stick with film, you are only limited in your ability to develop your own negatives. If you can do this, you will be able to continue with film for as long as you want. Scan the negs and save them in whatever format you want. It doesn't matter because the actual physical artifact is still in your possession.

    Not so with Digital.

    In many ways, digital is superior to film. However, when it comes to ownership of your data, you are far better off with film than you ever can be with digital.

      With my camera I shoot in RAW. By some process in history, today the RAW format for my specific camera is open - available not only for use in commercial products like Adobe, but in GPL'd software that will convert it for me and for while I have the source.

      Unless someone arrests me and confiscates all my software, as well as removes all this purportedly legal software from the market, what is the risk of using this camera?

      Just to nitpick a bit, most of the professional photographers I know use the various plugins to Photoshop to work with RAW images, so technically they aren't being forced into an upgrade path by the camera manufacturers. I personally use a Canon 10D, and the Canon software is so awful that I always use other tools to convert and manipulate the images.

      I fully agree with your point that it would be better if the camera manufacturers fully opened up their file formats, and I fail to see how keeping them closed provides them an actual competetive advantage. However, so long as there is no constraint against converting RAW images to another lossless format I'm not sure that this is a battle in which the camera companies can be accused of trying to pull a fast one on consumers; I think it's merely a case where they need to be educated about the further benefits of opening up their formats (ie open source developers can build free tools, etc).

        RAW format seems the best starting format for achieving best results in image manipulation (at least that was the message of an earlier /. discussion).

      Oh you mean you'd rather use propriatary film with propriatary developer chemicals? There is nothing particularly "open" about that besides that the chemicals are available to buy in most photography stores. If they go out you will no longer be able to develop your old exposed film.

      Besides, there is always DCRAW which allows you to "develop" your RAW files in an OSS fasion.

      Furthermore the reason RAW formats vary between makers is because it is raw data from the CCD/CMOS. So it's not strange at all that different manufacturers use different formats.

    The RAW format wars seem an odd competiton between camera manufacturers, who are actively hurting their presence in the professional space by making their imafes less useful for archive purposes and less interoperable for press agencies to sell. The thing that is particually noticible is that manufacturers are now being actively co-opted into sharing this information under NDA with MS to allow the hardware to work seamlessly with Longhorn.

      This is true, and unfortunately Canon can afford to take this position. In the DSLR market -- the *serious* digital photography market -- Canon has through various reports a 50-70% market share. Their only serious competitor is Nikon who controls anywhere from 30-50% depending upon who you listen to, and the rest make up a very small percentage. Kodak just announced a complete retirement from the DSLR market, Sigma cameras are doing horribly, and although Pentax and Minolta have decent offerings their market penetration is relatively weak. Canon can throw around threats since Nikon is WORSE in their disregard for RAW, actively encrypting (weakly) the white balance data. Nikon knows the encryption is a joke, but its enough to have legal teeth via the DCMA and thus Adobe won't translate it.

      Personally I'm more concerned with the retirement of RAW formats than the current vendor specificity. When you by a Canon EOS system or a Nikon F-mount you're buying into a closed, proprietary hardware system. Extending it to the software realm is crappy, but not surprising. Microsoft is best positioned to bust this wide open, and its in Adobe's best interests to open RAW or see the success of DNG. My guess is once the balance of power starts shifting heavily in favour of Canon or Nikon (towards virtual monopoly) the lesser company will open up their RAW format to be more accomodating.

I bought my first Canon digital SLR like 3 years ago and it was already a 3rd generation dSLR. A few years ago, for digital SLR's the choices were Nikon or Canon. That was it. Now, there's Pentax, Olympus, Minolta, Sigma, Kodak, and other stuff like the digital rangefinder by Epson (an interesting device, but not really mainstream).

    Hm... Everytime I read something similar to the article (that is about twice a week), I think that there should be a non-profit organisation to oppose taking away customer rights under the guise of "intellectual property".

    Something powerful enough to organise boycott that would cause *pain* to the offending company. Something that a congresscritter would be afraid to piss off. EFF comes close, except that it a) has a broader scope and b) sadly is not powerful enough.

    Too bad that the existing consumer organisations are focused on making money from their "consumer reports" and the general population doesn't care (the frog is half-boiled and still comfortable).

    • You could expand on this and say that each RAW format specification should be left in escrow. One of the conditions for public release could be that the format is no longer supported by any devices currently in mass production. Obviously this would work best for formats that are used in mass produced devices in the first place.
      Other conditions could be:
      • The company that owns the IP goes out of business.
      • The company decides to donate it to the community.

    so far my experience with canon gear has only been positive. firstly, they released linux and osx drivers for an old inkjet i had, along with most of their current line, and a good number of their scanners. second, their cameras are amazing, and use normal sd and cf cards instead of the MS and XD that are becoming infuriatingly ubiquitous. Also, their printer lines tend to standardize on the same types of ink, with better quality than the hp's and terrible machines epson is putting out nowadays (my r300 photo printer ran low on lt yellow ink, so it won't print black and white and keeps nagging me in windows to order more ink).

    i suspect this is just canon usa marketing dicks playing bs politics for their own sake. so far theyve given out a lot better specs for most of their printers than most companies, and few printer mfg's will even bother to put out cups drivers for their lines.

    not releasing their RAW format seems amazingly petty, but sounds exactly like all those fat, middle-aged sales execs who thought it wasn't worth it developing open-sourced linux drivers, cause they could get more commision charging each customer for the drivers themselves. we released them anyway, but a lot of those types make VP and do stupid shit like this to try to throw their cock around.
    • One of the comments to the post about Canon specifically points out that they only released the printer specs after being put under pressure, though. It's not as if they were overly enthusiastic about it.

Then I tried to sign of for Nikon's SDK to compare them and found that they are have a contest of who can be the biggest asshole. Both companies ship a camera control program for Mac & Windows that I would say is like a demo in terms of quality and usefulness.

    Raw image may theoretically contain a tiny bit more information under some circumstances. But you have a cost/benefit tradeoff: store and manage terabytes of raw images indefinitely vs. just achieving the same quality by using higher quality imagers together with standard image formats.

      Most raw formats on modern cameras is compressed using a lossless format. Take Nikons nef format, a 6.1mp image in raw is only about 4-5 MB, if this was not compressed it would be closer to 10 MB.

      You can not tweak certain settings as easily once the image is convert to another format, even a lossless one like tiff. Best example is white balance.
      • Actually, NEF is a bad example because some versions (D100) implement lossy compression.

        White balance is just as easily adjusted in TIFF as it is in a RAW format as is most everything else. It's simply a matter of what tools are available. The only thing you lose is the opportunity to do the demosiac over again.

    You do not need manufacturer-specific formats to do this. There are a bunch of formats you can use that store the data in a vendor-independent form and still let you recover the original data.

    The most important thing about such formats is that they need sufficient depth (16 bits per channel), they need a choice of los

    • For the vast majority of people taking pictures, JPEG is fine. The file size is relatively small, meaing that a lot of pictures can be stored on removable media, and the compression is pretty much unnoticeable.

      The problems come when you save the same image multiple times. Each time you save a JPEG image it's compressed a bit further, with a loss of more information. Eventually, you can be left with a fuzzy mess. It takes a couple of times for it to become noticeable, but it happens. For the vast majority o

    What is this "RAW" format?

    RAW doesn't really refer to any single file format. RAW refers to pulling the unprocessed (raw) sensor data out of a digital camera. The actual layout of the bits varies from brand to brand, and often from model to model.

    Why do photographers want access to the raw data anyway?

    Many professional/prosumer photographers like to archive the version of their work that contains as much of the originally captured information as possible. In the professional film world, this meant processed slides (for consumers, this meant processed negatives). In the digital world, the RAW file contains all the data captured by the camera, before some data is lost by compression and other data is added through interpolation.

    Can't they just pull a lossless image out of the camera and be happy?

    No. The very act of converting the raw data into an image involves lossful processing of the data. Out of gamut color data is discarded, and CCD color data is interpolated to fill surrounding pixels.

  • when it comes to doing any sort of real editing JPG is *NOT* an option. I see people here that are obviously not photographers or have not used a digital slr camera saying just to use JPG. If you plan on doing little to no post processing sure use JPG but for true manipulation RAW is essential
