Aperture incorrectly reading white balance data from RAW file?

I'm having some problems with both Aperture 1.1.2 and 1.5 importing RAW files from a Nikon D70 and a Canon G6. In both cases, Aperture is not reading the "as shot" white balance correctly.
With the G6, Aperture is always setting a fixed color temperature of 6016K, and a fixed tint of -15, regardless of the image in question. If I read the same image using Adobe Camera Raw, or Lightroom, then it I get the white balance value as set in the camera.
With the D70, it's picking up a different white balance value from the one set in the camera, always one far warmer than it should be, and with a green tint. Again, the Adobe tools get the right value out of the RAW file. With both cameras I have experimented with setting the white balance manually on the camera, and also with the "auto white balance" setting, but it makes no difference to Aperture.
Obviously I can change all of the values manually, but it's very time consuming, and in most cases the in-camera value is pretty close to what I need, so I'd much prefer Aperture to use it.
In any case, I'm worried about the discrepancy between Aperture and Camera Raw on something so basic.
Anybody got any ideas? I'm hoping I'm just doing something silly, as I have only been using Aperture for a couple of weeks, and maybe something is mis-configured.
Thanks

In any case, I'm worried about the discrepancy
between Aperture and Camera Raw on something so
basic.
Sorry I can't help you directly with Aperture as I haven't bought it - yet. However, re-the above quote, I'd just mention that the interpretation of colour temperature values is not quite as simple as it might seem. Even more so when you bear in mind that RAW converters from 3rd parties like Adobe or Apple are not based on the RAW conversion engine produced by the camera manufacturer - in effect they have to guess/estimate what the temp/tint values in the RAW file actually mean...
Some time back I made a series of tests using 3 Canon cameras, with ACR, Capture One & the Canon RAW converter. Each produced noticeably different results, and C1 & ACR showed quite different temp/tint values. (The Canon software only showed 'As Shot' - no values). The differences were consistent between shots from each camera (using WB values input or AWB) - but they weren't consistent from one camera to another. Which program produced the best result depended very much on the Camera/Subject/Personal taste...
Hope someone can help with Aperture specific info, I'm sure there must be a way of making camera specific adjustments to the RAW conversions...

  • Does Lightroom read white balance settings in NEF files?

    I have noticed an interesting difference in white balance color temp using Lightroom vs. Capture NX: In a Nikon D70 RAW shot (with camera white balance set at Direct Sunlight, no fine-tuning) Lightroom shows the "as shot" color temp to be 4850K. Capture NX reads the as shot color temp to be 5200. If Lightroom is reading the NEF w.b. settings, why isn't it reading the K temp as 5200?

    >Because of the different camera profiles being used, when matching white balance values Camera Raw can either match the white balance appearance (which colors are exactly neutral) or the white balance numbers (exact Kelvin/Tint numbers). In these cases, Camera Raw chose to match the appearance, not the numbers.

  • How can I Read lines of data from a file starting at the end of the file??

    Can anyone help me with how to read lines of data starting from the end of a file instead of the beginning?? I do not want to load the entire file into memory as the files are very rather large. Instead I want to start at the end of the file and read lines backward , until I find the particular data item i am searching for, then stop.
    Can this be done in Java ? I know it can be done in Perl.
    Thanks.

    Thanks for your suggestion about the RandomAccessFile, I did actually thought about that approach , but wasn't sure it would work.
    I do not want to read the file in a sequential forward manner because the files contain large number of lines of data that have already been processed and therefore there is no need to reprocess these lines of data.
    The Unprocessed lines are always at the the end of the file and these are the data lines I am interesting in getting at without having to read the entire file. Therefore, i figure that if I can read the data from the end of the file then this would be much more efficient.

    We don't have many samples left for Windows Phone 7 + Azure, the closest one to what you want to do is probably:
    Using Local Storage with OData on Windows Phone To Reduce Network Bandwidth
    this sample uses the local database feature: 'LINQ to SQL', available to Windows Phone 7.1 and 8.0 Silverlight applications, instead of simple file storage but even if you choose to stick with simple file storage I believe you should be able to adapt the
    networking related portions of the sample to your particular application.

  • Problem in reading Sql server data from text file.

    I am selecting record from sql server 2005 and save the result in text file.
    The text file contains , delimiter.
    I am reading same txt file from java & insert into database.
    But it shows "��S and box like characters along with original text.
    Regards

    I also tried a lot for this. And didn't want to do copy paste for all .sql files. Finally the files could be read as is the clue is to read the file using UTF-16 format like
    BufferedReader br=new BufferedReader(new InputStreamReader(fis,Charset.forName("UTF-16")));
    I guess it would help and save work to copy paste text to other files and resaving it!

  • How do you make iTunes read updated tag data from a file?

    This is such basic functionality that I'm sure I'm just missing it. It used to be the when I modified a file using a third party application (or editing a shared library using iTunes running on a different machine), all you had to do to get those updates into iTunes was select, hit "get info" and click OK without changing anything. That broke in 9.2 - it still recognized that the file has changed and adjusts the Date Modified field, but doesn't actually update any of the fields.
    The revised tags don't get updated until you either Get Info individually on each file, play the file, or modify the files. So realistically, there are no workarounds - the first two aren't realistic for a full library and the latter trashes your modification date and causes the refresh to take hours to complete if the library is on a remote server, rather than the ten minutes it used to take.

    Hi,
    I've written a script called UpdateTagInfo which should do the trick for you. Just select a bunch of tracks or an appropriate playlist and call the script. It will process each track, updating the tags if they've been changed externally. When complete it will tell you how many tracks were processed & how many were updated.

  • Reading Unicode data from a file...

    I am writing an application that needs to read some configuration data from a file. An end user edits the configuration file to provide the configuration data. The Java code reads this file and uses the configuration data supplied by the user.
    The user can also save non-ascii characters as part of the configuration data. hence, I do not want to use java properties files. What are the other options available that allow me reading Unicode data into my Java code and will also allow user to save the configuration file as Unicode?

    Java characters are Unicode characters. Read file data that consists of Unicode characters as Java characters or strings.
    You can read the data as primitive char values using the DataInputStream class. The InputStreamReader class can also read Unicode (UTF-16) data.
    Data can be written using the OutputStreamWriter class.

  • Does Aperture always apply white balance to RAW files?

    Hi Aperture users,
    I have been an Aperture user for many years.  Aperture handles the white balance of my Canon XTi RAW files just as I want it to: it interprets the RAW data by applying the white balance selected at the time of the photo.  I.e., when Aperture decodes the RAW file, it makes it look more-or-less like the in-camera JPG with respect to the white balance.
    However, in the past several months, many well-known contributors of this forum have stated "RAW is RAW -- Aperture will not apply any camera settings."  This statement was made in response to many "novice" questions about why a RAW photo in Aperture did not look anything like the JPG from the camera.
    So, my questions:
    Does anyone have a camera to whose RAW files Aperture does not apply in-camera white balance settings?
    Does everyone else agree that this exception to "RAW is RAW" is acceptable?
    thanks,
    nathan

    Hi Nathan -- I was hoping someone much more informed than me would weigh in with some engineering truth.  All I got on offer is the thin gruel of observation.

    1. I don't.  RAW is sensor data.  Most cameras record the White Balance camera setting as a metadata tag attached to the RAW data  (The WB has no effect at all on the captured data.)  Most RAW converters use this setting as the default WB.  Some RAW converters perform "colorimetric interpretation" -- they basically compare the data captured to a generic color space and assign a WB.  (This is, I assume, the same thing a camera set to "Auto WB" does.  My camera is superb at assigning a WB for any mixed scene; it's repeatably bad, though, whenever the actual scene is truly colored (meaning "away from average").)  In both cases -- 1. using the attached-to-the-RAW-data WB, and 2. analyzing the captured data to intelligently predict the WB -- a WB is applied to the RAW data.  It has to be, in order to produce an image from the data.
    2.  The problem here isn't that this is an exception -- it's that different people mean different things when they say "RAW".  The RAW data is RAW data.  As above, the WB setting has no effect on it.  But the image derived from the data -- any image produced from the data -- much have a WB set (and, for human use, a tone-curve applied).  Some people mistaken think that RAW is an image format, or that the image produced by the RAW converter is a "RAW" image.  It is not.  RAW data must be converted to an image format in order to be displayed as an image.  The conversion must apply a WB.
    I have found it useful (though perhaps mistaken) to conceive of my data-gathering to picture-making as following these steps:
    . Capture a pattern of light.  This is just data.
    . Convert the data to an image.  RAW conversion done by Aperture.  (NB: the settings for this can be changed.)
    . Adjust the image to my artistic satisfaction
    . Convert the adjusted image to an image format file
    . Publish the image-format file in one or two now standard forms: to be viewed on a computer monitor, or as a print.
    I mention only because at some point I consciously added the "Convert data to image" step in order to better grasp the process.  RAW data is RAW data -- but that step identifies an intermediate that many overlook.  At that step the information recorded along with the RAW data and stored in the RAW file is applied to the RAW data.
    To me, "RAW is RAW" is correct.  "Aperture will not apply any camera settings," is wrong.
    I am happy for any clarifications or corrections.

  • I have just bought a Panasonic Lumix compact camera. Aperture and Preview can't open the RAW files from this camera. Panasonic recommend downloading 'SYLKPIX Developer Studio SE' to save RAW file formats.How can Aperture and Preview read the files?

    Either use 'SYLKPIX Developer Studio SE' to develope the RAW files and to save them in another lossless format like TIFF, or try if Adobe's free DNG Coverter can convert your Lumix RAW files to dng. Then import the dngs. This way, your files will still be RAW files.  This works (most times) for my Lumix FZ28.

  • Aperture 3.1 - White Balance Doesn't Update

    Since upgrading to 3.1 I have noticed a somewhat annoying behavior with the White Balance data.
    When I change from one selected image in a project to another image the White Balance data does not update.
    If I deselect so no image is displayed and then select the new image, the data does update.
    This only happens with images on which I have not made a manual White Balance adjustment. If I have made an adjustment then the data displays correctly on the adjusted image when it is selected. However, then selecting an unadjusted image causes a reversion to the 'incorrect' behavior.
    Note that the image appearance does not change, so the actual image is not affected by this, only the display of the data.
    Is anyone else experiencing this?
    If so - any suggestions on how to fix?

  • White balance information from camera lost?

    I don't know what's up with Lightroom and reading the white balance data stored in the .nef files from my camera. Quite frankly it seems that Lightroom eighter has some "interpretation" of Nikon's colors, or that it simply disregard all white balance info.
    Is this problem .nef (Nikon)-specific, or does this whitebalance/color-interpretation problem appear with all raw formats?
    //Svein

    I calibrate against a CBL. As for "how far off", that depends on what calibration I've gotten, but it seems that Lightroom has a predefined "as shot" that is nowhere near the calibration done in-cam. I have verified this against what NX and Bibble gets, and for direct 60degree-north sunlight, Lightroom's interpretation is visibly blue-ish.

  • Retaining custom White Balance on importing Raw IR files

    How can I stop LR from changing my custom White Balance on importing RAW Infra Red files_

    LR does interpret camera-embedded WB numbers but it is limited to 2000K on the red end.  Is your custom WB below 2000K?
    The way around LR not being able to go red enough for IR is to make a custom camera profile with the DNG Profile Editor that includes a negative WB calibration shift, which can further subtract from the normal limit of 2000K.  That still won’t help translate a camera number to a LR number, I don’t think, but it would help you apply a LR-computed number to your IR images, normally by eyedroppering your Custom WB raw in LR with the IR profile place.
    Tutorial 4 on page 8 of the DNG Profile Editor documentation describes what to do for IR photos:
    http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/cs6/ DNGProfile_EditorDocumentation.pdf
