What additional features are available for the raw files?

When I'm working on the raw files in lightroom, I notice nothing else I can do with them that I can't do with JPEG files.  With the JPEG files I can adjust the balance of whites and pretty much everything.  When you work on a raw image, I see no difference in what I can do.  However, the controls are there.  So, what is the difference?  Thank you for your help.

From a functional point of view, the RAW files are usually rather larger than JPEG files, but can be a joy to work with the help of Adobe's Camera Raw (the engine which results in Ps and Lr modifiable RAW).

A few points:

1. all JPEG images (from RAW files) are compressed down to a depth of 8 bits, so, technically, we don't work with almost as many possible colors as for RAW formats (which are the property of the manufacturer of the device). »

2. According to what you read, you may fall on the apocryphal information that says "your camera does no change for RAW images that capture." It's not exactly the case: all the cameras 'interpret' the 'Photonics' image data entering the CMOS sensor from behind a table of Bayer (in general). Depending on which filter through the matrix Bayer, that a photon passes through, the camera interprets the electronic data from the CMOS as red, green or blue light. There are several other "interpretations" as well.

3. on these two points: http://www.luminous-landscape.com/tutorials/understanding-series/u-raw-files.shtml

4. I found that with my digital SLR 'starter', (sad, sad) 10Mpx files aren't as pleasant to work with, say, my T3i 18Mpx files. So beware, if you have a camera Mpx lowest, you won't see much change with each increase in "Blacks" for example (or 'contrast', 'fill light' or 'brightness') than you will with a model more great.

But, working with RAW images, these other reasons and is better than to work with JPEG images. Link to this post Forums Adobe to learn more: http://forums.adobe.com/message/2690352

  • Is only available for the xmp files RAW files?

    When we develop a RAW with Camera Raw image, we always get a file with all the settings xmp,

    But after that I developed a JPG image, I saw that the Raw settings of the camera icon appeared above the upper right of the thumbnail of the image in Bridge.

    However, I couldn't find the xmp file.

    Is only available for the xmp files RAW files? Jpg or TIF don't have for their Camera Raw settings xmp files?

    For JPG and TIF files - adjustments are classified, by design, in the metadata of the file rather than in a file "Sidecar".

  • What metadata are cooked in the vs file stored on the XMP file?

    I have read articles and even the cc manual and learned that some of the metadata is cooked in the file itself, I have to confirm that (which don't have the manual, but I am parinoid I read as bad now), as well as understand what information is. Reason: The company that I work has had problems with files that have been moved around location and I hope that the bridge is the answer for that. So if the information is cooked in the file itself, and the file is moved, a quick search in bridge will always evoke the file. Thank you for your time.

    Hi akjackson,

    > The company I work for has had problems with files that have been moved around location and I hope that the bridge is the answer for that. >

    You can see for yourself in Bridge by selecting "View > Show Hidden Files." The XMP files are sidecar that store settings for the raw files of most of the cameras. Files NEF or CR2, for example, will the XMP file in the folder even if you kept the default Camera Raw default preference to save the settings of the image in .xmp sidecar files. If you copy or move your file to another location, however, the XMP file will go with it. Just do not use the option to save the image to a database of Camera Raw settings if you want to be as sure as possible that metadata from anywhere that the file will go. The XMP file should not be visible to travel even if you are burning a DVD with the main file, or move it on a network. It will simply go with the parent file.

    Nothing can be written as a normal raw file, so the XMP file is needed. However, you can save in the DNG raw with your changes intact Camera Raw, as well as key words that you've added, without losing your XMP data. DNG is a special wrapper that keeps the file raw inside.  Other file formats also store metadata in the file itself, rather use the XMP sidecar files.

    So basically, if your business loses its files, it really has nothing to do with the XMP sidecar files. It has to do with the not not using metadata, including keywords, to search for files, and/or a good system to organize the files themselves within your network. Bridge, btw, can only see the drives that are connected, so make sure that you do not send your files offline readers and optical media, and bridge to know where they are still waiting. It will not. If you need that, you need a digital asset manager.

    If you are still feeling paranoid, or need to prove to your bosses (that is the company, after all), prove it to yourself by the fire from the Finder, a DVD with files camera raw, DNG, JPEG, TIFF, etc. files, after adding keywords or make changes to the image files. Remove the DVD and put it into another computer running the bridge. You have moved the files and you should be able to see their metadata always there, and files camera raw will have their files XMP on the DVD if show you hidden files in the bridge while viewing.
