RAWs are 12 or 14 bit memory dumps, a JPEG is a lossy 8 bit image. You'll be able to show artifacting in a fabricated RAW even from the best JPEG simply due to aliasing in the shading of each sensor. The reason you don't see software for converting to RAW is simply because RAW is not a standard, it's just a very loose term for a memory dump from a CMOS or CCD sensor after the second curtain closes. It varies from sensor to sensor and from firmware to firmware.
No joke, a Canon 1D Mark II (my camera) with 1.1.0 firmware produces a different RAW than a 1D II with firmware 1.2.6, and when you get a firmware update sometimes you have to wait for a patch to your converters.
The actual image is created using bayer interpolation, and while I suppose you could do some sort of reverse, it isn't exactly as straight forward cut and dry as it may seem. The output image really could be equated to a hash of the RAW, to put it simply.
Yes, what I meant was to a specific range of sensors. All of the 1D mark II sensors will produce the same format, but a 1D mark IIN will produce a different format, for example.
Sounds like you've never edited a RAW file. All of your edits are stored sequentially in a sidecar XMP file and applied to what you see every time you load it, or saved as a preview JPEG also in the sidecar XMP file or some other metadata depending on the software you're using. The RAW file remains untouched.
Well, a RAW is pretty much just a state dump from the sensor - it's not an image at all, an image is created from it using various interpolation techniques and it varies from sensor to sensor.
Creating a RAW isn't something as simple as saving an image as RAW. RAW is not an image format, it's just a term for what amounts to not much more than a state dump. If you don't have the sensor specifications, it will not be nearly as easy.
That aside, most photographers take more than one shot, and pick the best out of them. Just having the other three or four shots of the same subject and bringing all of them to court while the other person brings a crop of your original shot is more than enough.
And as I mentioned in a previous post, RAW files have the camera's serial number embedded. Show up with the RAW and your camera bearing the same serial number, and wham bam thank you ma'am, there you go. No doubt about it at all.
That still applies in photography with RAWs. They have the serial number of the camera that took them embedded in the data, and they can't be edited, only converted and saved in a different format and then edited. The original RAW is just a dump of the sensor's state immediately after the shutter closes. They're also huge proprietary formats, and I don't think any photographer uploads them to stock sites.
On top of that, they're held as a much higher form of evidence than say a JPEG in court as they are extremely difficult to tamper with. Since a RAW image is not even an image, but just a memory dump of a CMOS or CCD, you'd have to know the specifics of that exact chip in order to edit it, and the only people who know that usually are the manufacturers of said chip.
I had a MacBook Pro that got wrecked in an accident, I would have sold it to you for $1 if you wanted it, but I'd be willing to bet $2800 that you wouldn't be able to do much to make it work. The thing was completely totaled.
May I provide some information to the moron who sent a letter off to Wordpress about Fake Chuck Westfall? Maybe you guys should research what you proclaim to have degrees in, namely THE LAW, before you send out frivolous complaints.
1. Parody.
---
A parody, in contemporary usage, is a work created to mock, comment on, or poke fun at an original work, its subject, or author, or some other target, by means of humorous, satiric or ironic imitation. As the literary theorist Linda Hutcheon (2000: 7) puts it, "parody ⦠is imitation with a critical difference, not always at the expense of the parodied text." Another critic, Simon Dentith (2000: 9), defines parody as "any cultural practice which provides a relatively polemical allusive imitation of another cultural production or practice."
Parody may be found in art or culture, including literature, music (although "parody" in music has a rather wider meaning than for other art forms), and cinema. Parodies are sometimes colloquially referred to as spoofs or lampoons.

According to Aristotle (Poetics, ii. 5), Hegemon of Thasos was the inventor of a kind of parody; by slightly altering the wording in well-known poems he transformed the sublime into the ridiculous. In ancient Greek literature, a parodia was a narrative poem imitating the style and prosody of epics "but treating light, satirical or mock-heroic subjects" (Denith, 10). Indeed, the apparent Greek roots of the word are par- (which can mean beside, counter, or against) and -ody (song, as in an ode). Thus, the original Greek word parodia has sometimes been taken to mean counter-song, an imitation that is set against the original. The Oxford English Dictionary, for example, defines parody as imitation "turned as to produce a ridiculous effect" (quoted in Hutcheon, 32). Because par- also has the non-antagonistic meaning of beside, "there is nothing in parodia to necessitate the inclusion of a concept of ridicule" (Hutcheon, 32).
Roman writers explained parody as an imitation of one poet by another for humorous effect. In French Neoclassical literature, parody was also a type of poem where one work imitates the style of another for humorous effect.

Parody is a frequent ingredient in satire and is often used to make social and political points. Examples include Swift's A Modest Proposal, which satirizes English neglect of Ireland by parodying emotionally disengaged political tracts, and, in contemporary culture, The Daily Show and The Colbert Report, which parody a news broadcast and a talk show, respectively, to satirize political and social trends and events. Some events, such as a national tragedy, can be difficult to handle. A 9/11 update of George Orwell's novella Animal Farmâ"Snowball's Chance by U.S. author John Reedâ"raised the ire of the George Orwell estate, and critics such as Christopher Hitchens. Chet Clem, Editorial Manager of the news parody publication The Onion, told Wikinews in an interview the questions that are raised when addressing difficult topics: âoeI know the September 11 issue was an obviously very large challenge to approach. Do we even put out an issue? What is funny at this time in American history? Where are the jokes? Do people want jokes right now? Is the nation ready to laugh again? Who knows. There will always be some level of division in the back room. Itâ(TM)s also what keeps us on our toes.â
Parody is by no means necessarilly satirical, and may sometimes be done with respect and appreciation of the subject involved, while not being a heedless sarcastic attack.
Parody has also been used to facilitate dialogue between cultures or subcultures. Sociolinguist Mary Louise Pratt identifies parody as one of the "arts of the contact zone," through which marginalized or oppressed groups "selectively appropriate," or imitate and take over, aspects of more empowered cultures.
Shakespeare often uses a series of parodies to convey his m
Why is an article about a game that was released in mid 2007 tagged classicgames? Quake is a classic game, Enemy Territory: Quake Wars certainly isn't.
I know a few pros who have openly stated to me that they'd take a 5DII over their 1DsIII. However, the 1DsIV is right around the corner, so that's going to be a moot point shortly.
Interesting, seems kind of random that HP would do that, they aren't very much at all known for cameras, and as far as I know never even put out a professional camera.
I wonder if Canon has already gone into a licensing agreement with Nikon. I haven't heard anything about any lawsuits, and I don't think Canon would really want to lose business over this. I haven't been able to find an original release date for the Canon wireless unit, but at this point I'd be willing to bet money that you're right about Nikon beating Canon to the punch with it.
Canon's pro line of DSLRs have had wireless transmitters available for a while as well, I believe predating Nikon's transmitters. I don't know Nikon's lineup all that well, so I may very well be wrong on that though.
The wireless transmitter sits on the side of the 1D series, and the smaller body (5D, 40D, 50D, etc) transmitters take the place of the battery grip and don't provide extra battery power, same design as Nikon's wireless transmitters. Nikon has a better design on the battery grip though.:p
I can't find any reference to Nikon having a patent on wireless transmission of photos from a camera, so if you could provide a document backing that up it'd be nice.
I used to do that with my old T-Mobile phone, but now I just have a Sprint PCI-E mini card built in. It's a hell of a lot more convenient than using a tethered phone.
I wrote up a script that uses traceroute to determine whether or not I have Internet connectivity via 802.11 or my wired Ethernet jack, and if not, it automatically connects the Sprint card. When I have 802.11 connectivity it traceroutes to the nearest Google box every 30 seconds or so and if it notices that I'm not going out through Sprint (yay interface priority) it disconnects the Sprint card. My laptop's WiFi switch turns the entire shebang off, so it's kind of like a "I can has interwebs?" switch.:)
BTW - a lot of the designers would resent to be called 'American'
Obviously you have never been to a NASA facility.
Obviously you have never been to Florida (Cape Canaveral is in Florida). At least in the Miami area, being only an "American" and not a [Cuban|African|*]-American is both a shame and dangerous.

I tethered with the MDA all the time when I was with T-Mobile by using it as a Bluetooth modem. They never complained once.

I see your point; I suppose the best way to say it is that these games do nothing at all for me. I'd much rather just do the real deal. :)
Just pointing out the parent AC post here because it is SO DAMN TRUE.
Playing a real instrument and writing your own music is a lot more fun and much more rewarding than mashing buttons with Guitar Hero.
Yes, I play guitar, bass, and piano, and am classically trained, so I'm a little bit biased.
Because, you know, wildlife photographers take their pictures with their cell phone and not something along the lines of a Canon 1DsIII or Nikon D3x.
