This is one of the benefits you get from shooting raw.
You can't recover highlight or shadow detail from a JPEG because it has 8 bits of color depth per color component[1], and it's mapped so that the lowest pixel value is interpreted as "black", and the highest is "white." There simply is nothing below black or above white. The creators of JPEG did this ...

RAW certainly gives a lot more after-the-fact flexibility. But, it's generally true that if the exposure is correct and white balance set to match the lighting, that flexibility is less important. If you're happy with the processing options the camera gives (and, especially for higher-level cameras, such options are extensive), RAW isn't really a necessity.

It really depends on what you mean by "photographing an event". If on-site printing/sales are part of the deal, then the photographer would have to be an idiot to shoot RAW; it would just increase turn-around time for no benefit, and every delay is lost sales (that part of the trade is highly impulse-driven). So if the "event photography" is mostly a matter ...

The command-line utility dcraw can do this, using the dcraw -e flag. However, it apparently has issues with large images in Windows Vista and Windows 7 (see the FAQ on that page).
IrfanView displays the embedded JPEG when opening some forms of RAW. If it's able to open your type, you can simply open the RAW and do a "Save as --> JPEG".

That would go against the purpose of a reset. What is most likely to be closer to what you are looking for are custom memory banks. IIIRC, the D700 has 4. You save settings in each bank as you like and then the camera uses them when you select a particular bank. Most but not all settings can be saved this way.

No, you don't need to be nervous yet. You may need either an updated version of Adobe Camera Raw or if an up-to-date enough version isn't available for your camera, then you may have to use Nikon's RAW tools (ViewNX) to do the initial adjustments to your photos. Once you get the photo looking the way you want from the RAW handling software, you can export ...

Free, open source, cross-platform software PhotoRec can specifically recover many RAW formats, including Sony ARW (as well as Canon CR2, Nikon NEF, Pentax PEF, and others).
Although the interface isn't particularly slick, the underlying functionality is the same as any proprietary program, and I'd be surprised if any of the more expensive options can ...

I think (I'm not sure though) there is no built-in command line tools for such task. Instead, you can use third party softwares. Allow me to introduce you to very nice ImageMagick.
It is a set of cross-platform command-line tools that allow you to do a lot. It has lots of tools and also many scripts based on it are available online. They have also a forum ...

Any general file recovery tool will do. For image-centric ones, there are also plenty available. The most popular ones are Image Rescue and Photo Rescue. They each offer a free-trial which shows you thumbnails and guarantee that anything that shows a thumbnail will be recovered once you pay. I can vouch that both of these work and I have seen them recover ...

Just so you know:
What you see on your camera is the embedded thumbnail in the RAW file.
What you see on the computer is the software's interpretation of the RAW file.
Most likely, your files are fine but the software is having trouble decoding the RAW files from your camera. This is a regular occurrence since RAW files are different between cameras. ...

Possible causes of the problem.
The memory card used is does not meet the standard requirement of the DSLR, e.g. (the required SDCard should be class 6, but the installed is of lower class). This can be a critical factor that's why it is wise to check the requirement first before buying. Not all memory cards are the same.
The Memory card is damaged. ...

Use DCRaw:
$ dcraw -e MyFile.NEF
You will get a MyFile.thumb.jpg. It should work just the same with Canon files.

I can only answer your second question - i.e. if anything can be done to resurrect these files. As others have mentioned, that uncorrupted version you're seeing briefly as you import them into Lightroom is the preview JPEG generated in-camera when you shoot RAW. There are plenty of tools that will recover those previews for you, hopefully even if the RAW ...

I think you have two questions:
what causes the file corruption:
bad flash memory, 80% of time.
When I view them in Lightroom or Windows Explorer, the files show normally for a split-second, then are over-painted with the light area you see below. Why?
Normal. A raw file usually embed a preview JPG and the program (OS, Lightroom etc) will first ...

This is often down to transfer from card to computer, not corruption on the actual card.
I have found that Windows Explorer tends to be the culprit - do not copy files from your card simply by dragging/dropping in Explorer - use a different tool.
I have used the free 'FastCopy' file copier with 100% success. It has a verification option that you can use to ...

None of the settings are "ignored", all the settings are used to produce the RAW preview image and to show information in camera like the histogram and the over exposure blinky thing - but some settings can be changes later in raw processing without quality loss.
The settings that effect light hitting the sensor (Aperture and shutter speed) are obviously ...

Dynamic range is the difference between the darkest and brightest portion of an image. JPEGs have to represent each color with 8 bits of information where as raw can use more bits (thus more possible values).
There are two options for how the camera can resolve the difference in bit depth. Either it can represent a smaller variation for each value ...

The histogram your camera displays is based on the in-camera jpeg preview generated when you save a RAW file. In the preview, the data is gone and unrecoverable. The information is still there in the RAW file, though.
Most cameras use in the neighborhood of 12 to 14 bits per color channel, but the JPEG standard only allows 8 bits per channel. When you ...

I've been on the client side of this argument - I paid a relatively hefty price to I get an electronic copy of my kid's school photo which was shot straight to jpeg under controlled conditions by someone who does it all the time... Let's just say if I ever meet that particular photographer I'm going to set their camera to raw and duct-tape the controls as ...

I can think of a handful of possible reasons to shoot RAW:
The "oops" factor. If anything at all needs to be corrected -- even if you believe it's properly set up during the shoot -- RAW gives you just a bit more room to do so. In virtually all cases, you'd very much prefer to get stuff right in-camera vs. trying to fix it later, so you can think about ...

The RAW files are different because the sensors are different. The processor does not do anything to the RAW data, it simply reads it and packages it in a RAW format. The embedded JPEG preview though is computed differently by these processors, just like a JPEG would.
In theory, yes, the phase-detect pixels affect image-quality but the effect is extremely ...

It depends on what you mean by ignored and which camera you are shooting with and which software you are using to do your RAW conversion. The settings that affect what the camera does before or during the exposure will affect the contents of the RAW file. The settings that affect what the camera does in the processor after the image has been exposed will ...

The answer - in general - none.
In detail: It depends.
For a Canon, shooting in RAW, DPP will give you the same (but less compressed) output as the in-camera JPEG conversion.
In contrast, Adobe's RAW converter has no idea what a picture style is (standard, neutral etc.) and ignores that setting as well as any other manufacturer specific setting.
Now ISO, ...

Still for better editing flexibility and best results, shooting in RAW is more advisable.
Editing flexibility in a sense of editing a photograph into creative shots. Example is turning it into an old photograph, or apply a selective color effects. with proper lighting, still it is necessary to shoot in RAW.

Well, maybe for a not so important but time demanding event like on news photojournalism where the most important thing is to deliver the images as soon as it was captured because of the tough competition (news companies competes for first aired or reported news), it is not practical to shoot in RAW. I personally shoot in RAW in a very special event and ...
