LR4 White Balance Numbers Differ w/ Nikon D4 and D3s

I've noticed that LR interprets the white balance settings differently for my raw .nef files coming from my Nikon D3s and D4 bodies; even when a specific kelvin temp is chosen in camera.
Here's a few examples:
D4 flash WB, LR shows as 6150, +2
D3s flash WB, LR shows as 6400, +9
D4 WB set to 5k, LR reads as 4750, +1
D3s WB set to 5k, LR reads as 4900, +10
Any thoughts on why this is happening, and what (if anything) I should do to get xxxx kelvin temp in camera to import as xxxx kelvin temp in LR?

  The white balance readout in terms of temperature & tint depends on the camera profile (more specifically, the translation between so-called "camera neutral" values and temperature/tint values). Different raw converters use different profiles. This results in different readouts, even if image appearance is the same.
The process of reporting white balance values is non-standardized. 
http://www.luminous-landscape.com/fo...2#msg411522%29
Raw converters, whether in the camera or in a computer, do not deal with color temperatures, they deal with multipliers applied to the red and blue channels. But because representing a WB as a pair of multiplier values would be mystifying for most users, the GUI translates those numbers into the corresponding color temperature that the WB will neutralize, a concept more familiar to most photograhers. When "As Shot" is set in the converter it reads from the image file metadata the mutipliers listed there and applies them. However, the WB multipliers are applied after the camera profile and since different converters use different profiles with differing renderings of the basic color values, the post-WB image values are different, even though the same multipliers are used, and the corresponding Kelvin temperature is different.
Now, what happens when you dial a temperature into your camera? The firmware calculates what multipliers will be needed in combination with the Nikon profile in order to neutralize light of that color. Then it records the multipliers in the metadata and, if outputting a jpg, applies them. But if you output a Raw, LR reads the multipliers and does the reverse calculation, "What temperature will be neutralized if these multipliers are used with an Adobe profile?" and does not come back to the same temperature that you set in the camera.
Different cameras = different profiles = different temperatures.

  • Wrong white balance in NEF files (Nikon D70 RAW)

    Hi
    I have a problem with NEF files: I shoot them with white balance set to Cloudy (6500K), however, in lightroom the white balance is shown as 5450K.
    There is a color shift because of this:
    When I leave the white balance at "As shoot" the image appears OK, however, changing white balance to "cloudy" which is supposed to do nothing, makes the image warmer, obviously because Lightroom believes that the image is shot at 5450K and converts it to 6500K, e.g. makes it warmer, while the image is already 6500K. Changing the setting to, say, "shadow", makes it even warmer.
    Of course I may try to correct the WB "blindly", disregarding the temperature value, but that's annoying.
    The camera is Nikon D70, unpatched.
    Did anyone have the same symphtom?
    Is there any fix or a workaround?
    Thank you,
    Gennady

    When the camera was set to "Cloudy" (6500K) then switching to "daylight" (5200K) makes the picture cooler, switching to "Shadow" (7500K) makes the picture warmer. This is how the camera behaves and this is how Nikon's NEF convertor behaves. Obviously, when the camera was set to "Cloudy", then switching between "As shot" and "Cloudy" should make no change, because "As shot" means "Cloudy", because the camera was set to "Cloudy".
    Now, for some reason, Lightroom believes that the picture was shot with a manual settings of 5450K. I don't know why it believes so.
    And thus, switching from "As shot" to "Cloudy" makes the picture warmer (although it should leave it unchanged), and switching to "Shadow" makes it even more warmer, far warmer that it should be at "cloudy" setting.
    What I expect is that switching from "As shot" to "Cloudy" in the Lightroom would give the same colors as switching from "As shot" to "Cloudy" in Nikon's NEF convertor. And apparently it does not work this way.

  • Iphoto not recognizing my preset manual white balance setting on my Nikon D3100

    hi there.
    i've been using iPhoto to edit my photos uploaded as RAW, from my Nikon D3100.  While i've been very satisfied with the results, i've run across a small problem.  i've used various white balance settings on my camera:  incandescent, flourescent, auto white balance, and recently started using the manual white balance.  when uploading pictures to iphoto, the photo has indicated what white balance setting i have used, except when i use my manual white balance feature, the information shows up as AWB (automatic white balance).
    can somebody please explain to me why this is?  any other setting i use shows up with the appropriate icon, according to what i choos on my camera.  is this a glitch?  what is the manual white balance setting icon supposed to look like in iPhoto?
    Again, I shoot in RAW, and upload directly to iPhoto successfully, as RAW.

    I think this article will help explain this 
    and this one from Adobe
    — Raw files have not had while balance set. They are tagged with whatever the camera's setting was, (either that which was manually set or via auto-white-balance), but the actual data has not been changed. This allows one to set any colour temperature and white balance one wishes after the fact with no image degradation. It should be understood that once the file has been converted from the linear space and has had a gamma curve applied (such as in a JPG) white balance can no longer be properly done.
    So the displaed WB is simply a tag and has no effect on the image - it is simply information about the camera settings

  • LR4 White balance tool changes to magnifying glass

    I just upgrade to LR 4.  However  in the develop module, whenever I choose my white balance tool and then hover over the image it changes to the magnifying glass.  If I click, all it does is zoom in and out.  The circle where the WB tool lives, is blank like it usually is when the tool is selected. 
    I've checked for stuck keys and still have same result.

    hmm.. I posted on here. Left LR open and did some other stuff for a while.  Came back to color correct WB tool-less and vola all of a sudden it's working.  we'll see for how long

  • Nikon D800 Flash White Balance

    When RAW files (either NEF or DNG) taken with the setting Flash White Balance, they are imported into either Lightroom(4) or Photoshop(CS6) with a temperature of 6150K.  This does not coincide with the Nikon default of 5400K.  If the Nikon Software (View NX2) is used, the white balance shows that the Flash setting was used and the image appears identical when their 5400 default is applied.  In Lightroom, or in CS6, if the temperature number is changed to reflect the Nikon default number of 5400K, the color of the image dramatically changes.  If the temperature is left at 6150K, the image appears virtually identical to what Nikon calls 5400K. 
    The issue, a minor one, seems to be that the Adobe products are applying an incorrect Kelving Temperature number to the files.  It is disconcerting to see the wrong temperature displayed in the software, but the number can be ignored without any negative effects; and the number can be modified to produce a more pleasing balance.
    I am writing only because it took some experimentation and time to come to these conclusions.  I wasn't clear, at first whether the camera was at fault, or if the software was producing the issue.  It would be beneficial to have the issue addressed and corrected.
    Incidentally, all the other White Balance settings from the camera seem to translate accurately into the Adobe Software.

    Nikon's white balance numbers are confusing.  Nikon list Direct Sunlight as 5200 degrees and Flash as 5400 degrees - no values are listed for tint.  If you open an NEF file with Nikon Capture NX2 and select Direct Sunlight for the white balance it will list 5200 degrees with tint of 0 for the white balance, and if you select Flash it will list 5400 degrees and a tint of 0.  You can adjust these values with sliders, and if you adjust the Flash values to 5200 degrees with a tint of 0 you do not get the same colors in the image as you get with Direct Sunlight selected which has the identical temperature and tint values. 
    I don't find any agreement between Nikon's white balance values and what you get with Adobe RAW processing software.  I don't find the presets in Adobe Software (Daylight, Flash, etc) very useful because they don't appear correct for the camera's I have.  I shot images (NEF Files) with every preset available in the camera selected and saved the white balance values as presets in Adobe Camera RAW.  I also find the Camera profiles more useful than Adobe Standard. 

  • Working Without White Balance

    Camera: Nikon D90
    Adobe CS5 Design Suite
    My goal is to work in Photoshop and Camera Raw without using White Balance.
    As I understand, the camera stores within the raw NEF file what was seen by the camera chip without correction. For example, if the camera chip sees say 10,000 red photons, this is stored as say 200. If the camera chip sees 20,000 red photons, this is stored as 400. Hence, it is linear. Of course, the actual storage is as a Bayer array.
    http://www.cambridgeincolour.com/tutorials/camera-sensors.htm
    In theory, from the raw NEF file, one should be able to reconstruct the image that fell upon the camera chip.
    On the camera itself, there are many camera White Balance settings. However, it lacks a "None" i.e. "As Is" setting meaning do not assume anything about the light source and make no correctons. Just record the photon levels and give me back the same image that was focused on the camera chip.
    As an experiment, I shot a daylight scene using 2,500K (obviously, an extreme value) for the white balance. When I look at the raw file in Camera Raw, the "As Shot" shows a heavy blue tint. Hence, Camera Raw was using the  2,500K white balance selecting of the Nikon for the "As Shot" setting in Camera Raw. Looking at the Camera Raw basic panel White Balance drop down  items, there is no "None". Hence, Camera Raw always assumes there is a White Balance and makes corrections.
    Why would I want to do this? For example, I have multiple varied color light sources. I want to see exactly the image my eye sees. I do not want the camera making corrections since there is not a single light source for it to make assumptions about how to correct.
    Is there a way in Photoshop or Camera Raw to show me the image without any white balance correction. Thanks in advance.

    The sensor is linear, but the sensitivities of the red, green and blue channels differ, so one must take these differing sensitivities into account when rendering the image from the raw data. As demonstrated by others, channel multipliers of unity (UniWB) do not yield the intended result. To obtain your intended result, empirically determined multipliers would be necessary. When used for white balance, these multipliers are chosen to that a white target will have equal RGB values in the rendered image. For your purpose, multipliers would need to be chosen so that the white target would assume the color of the incident light. In other words, if the white target were illuminated with reddish light, the image would be reddish and not white.
    Why would I want to do this? For example, I have multiple varied color light sources. I want to see exactly the image my eye sees. I do not want the camera making corrections since there is not a single light source for it to make assumptions about how to correct.

    I infer that you want the captured image to reflect the spectra of the actual scene luminances (or more likely a metameric tristimulus match) rather than how you perceive them. The human visual apparatus exhibits chromatic adaption, whereas the sensor does not. The CIE xyz model assumes complete chromatic adaption and the color models based on CIE models need a white point to operate, so you are attempting to use ACR in a manner other than for which it was intended. There is an interesting exercise on the Stanford web site that shows how one can use a digital camera (the Nikon D70) in conjunction with a spectrophotometer to obtain spectrophotometric data from the camera. To recreate the actual spectra, two additional colored filters are required, but if one merely needs a metameric tristimulus match, perhaps only the three native CFA filters of the camera would be needed.
    http://scien.stanford.edu/pages/labsite/2006/psych221/projects/06/clintonk/index.htm
    Going back to ACR, experience indicates that if one wants to recreate the appearance of a colorful sunset or a candlelit scene (cases that exceed the limits of chromatic adaption), a daylight color balance works best. It would seem intuitively that an equal energy illuminant (CIE Illuminant E) would be appropriate. This corresponds to a correlated color temperature of approximately 5455K.

  • 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?

  • White Balance Setting Errors - HELP!

    I am having a problem with Aperture and wanted to find if anyone else has noticed this since the update to 3.1.
    I imported a batch of photos (about 75 RAW 25 JPEG) and noticed that the white balance was the same for every picture. Odd since my Nikon camera is set to Auto White Balance and RAW and the JPEG photos from my Sony should show 5000/0. Everything was showing the same value, which was something like 4689/-5.
    I discovered that Aperture is only showing me the setting for the first photo I select after opening the program. Unless I deselect the photo by clicking somewhere on the background, that photo's setting will show for all photos that have not been locked into a setting by editing. After deselecting, I can then click on a different photo and get the correct white balance numbers.
    This causes a very annoying problem - I can't start editing a photo after directly clicking on it or moving to it with the arrow keys because the white balance starting point will be from a previous photo's setting, so I am moving the sliders from the wrong starting point. Having to deselect and reselect between every photo is very irritating.
    I've restarted my computer, repaired Aperture's permissions, and repaired the database, but nothing fixes the problem. It's likely a bug that needs an update to be fixed (I submitted a bug report) but I'm open to suggestions.
    Anyone else having a similar problem since updating?

    Others have reported simialr problems.

  • White Balance Discrepancies

    Hi All,
    I'm having a real head-scratcher here, and wondering if anyone else has run into this. The white balance in Lightroom is much different than what it's supposed to be (as set by the camera). For example (D200 NEF, sunny day, ~2pm):
    Camera WB setting: flash.
    Nikon Capture 4: 5400K
    Lightroom 1.4: 6150K (-9)
    WB: daylight
    NC: 5200K
    LR: 4950 (-3)
    WB: 5300K
    NC: 5300K
    LR: 5000K (-4)
    WB: 5600K
    NC: 5600K
    LR: 5250K (-6)
    You'll notice there's no consistent difference. What gives? Even stranger, when I flip back and forth between the programs, the images appear the same. I know LR and NC have different ways of converting NEF files, but shouldn't these still be reading as the same numerical temperatures?
    Thanks,
    Martin

    Even though Kelvin sounds quite scientific and the idea seems to be based on a scientific well-known concept (black body radiation) there is no standard for how to apply this to color rendition. This is obvious already from the need of a "tint" value. In a well behaved system, you should not need this as the black body radiator only has one parameter - its temperature. So the color rendition process is far more complex than just assuming a black body radiator!
    Here is some reading I found on this forum by one of the main writers of the ACR/Lightroom RAW code:
    >Thomas Knoll - 10:47am Sep 25, 05 PST (#1 of 101) Edited: 25-Sep-2005 at 12:57pm
    This is the normal and expected result of Adobe Camera Raw and Nikon using different camera profiles and algorithms, and is not a bug.
    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.
    Even if the white balance matches, I don't expect an exact overall appearance match since Camera Raw and Nikon software use a different tone curve and rendering algorithms for non-neutral colors.

  • White balance settings always display 5000K 0 Tint

    Been searching on this, found a few things, but nothing helpful.
    In the past few weeks, it appears that Aperture is no longer interpreting my cameras white balance settings properly. The colors themselves are fine, however, the adjustment applet always shows 5000k with 0 tint. I'm not quite sure when this started, but it's quite frustrating. This appears to be happening on everything newly imported. (I can only verify JPG at the moment, as I'm seeing this on a Canon S95 and 60D, which both don't have RAW support yet in Aperture).
    Anyone ever see this happen, or no of a solution? I'm using Aperture 3, latest updates etc. on OS X 10.6.4. My older files all appear fine, it's just these recents, from these two cameras. Unfortunately, I've sold my other gear, and don't have an older cam around to test. Either way, other products, Adobe, seem to be reading things properly.
    Thanks for any input.

    So all these files are JPEGs?
    Note that white balance works very differently with JPEGs and RAW files. There really is no "white balance" information in a JPEG, and you can't adjust them the same way. That's one of the big advantages of RAW files. I suspect once Aperture supports the RAW files for those cameras, then you'll get proper white balance. Until then, with JPEGs you're kinda SOL. It's a bunch more work. But that's the nature of the medium.

  • Open the same raw file in PS5 with two different White Balance settings

    I'm trying to open the same Raw File in PS5 with two different White Balance settings.  One setting "as shot" the other in "daylight", then blend them.  The tutorial I'm watching says to "stack" the images.  The tutorial shows one White Balance setting as the "Background" layer and the other setting as "Layer 1".  I don't know how to do this and the tutorial is not specific.  Can anyone either point me to a step by step instruction or offer some assistance?

    Also look at the "Snapshots" feature of Camera Raw itself.  It allows you non-destructively to keep multiple sets of settings for a single raw file.
    Learning about it far exceeds the scope of what can be done in this particular forum.  I would recommend this book as essential reading:

    1- Shooting with my Canon 5D, Mostly shooting with Strobes, Usually I choose a Custom white Balance shooting a Gray-Card. Or some-times I set it at:  5200- 5500 K.
    2- Later I shoot a Color-Checker with the same Lighting that I shot my Images In that day, and I Import the color-checker Image into Lightroom.
    3- I select the Eye-Dropper Tool, and I choose a white balance by clicking on one of the neutral colors inside the Lightroom .

    5- I Drag and Drop the DNG file into the Color-Checker, and I save my profile.( I can also export it as a Preset of Color-Checker from File-Export-Preset- Color-Checker Passport )
    6- I go to the Photoshop and I go to the Camera-Raw, and Open the Images and I apply the preset Manually to each Image one by one.

  • Loss of white balance correction

    I just returned from a dive trip. In addition to cropping, adjusting the exposure and cropping, I use the white balance feature to correct the color of photos taken without a flash at depth. I uploaded my cards to my MacBook Pro (both the laptop and my Mac Pro are running Aperture 2.1.3), and edited these images. When I got home, I exported the project (like I always do), and imported it into my main Aperture library on my Mac Pro.
    When I review these images, the color-corrected previews are seen in the Browser. When I click on an image, the color-corrected preview is shown in full size on my second, 30" Cinema Display while the RAW image is loading. However, once the full image is loaded, the white balance reverts to the original - but the levels and cropping are maintained! I can re-do the white balance correction, but once I quit and restart Aperture again, the white balance correction is again lost - but not my other edits! Thus, not only were the white balance corrections done on my laptop lost when I exported/imported the project, the repeat corrections done on my MacPro are lost when I quit and restart Aperture.
    Curiously, after I've re-done the white balance on several images and quit, when I restart Aperture there is no indication that there are any images or projects that haven't been backed up in a vault.
    This has never happened before when I would import a project; the last time I successfully imported a project with all of its adjustments maintained was February (I don't recall when 2.1.3 came out). I've searched this forum to no avail; has anyone else experienced this?

    I've the x-rite passport and I can say only a thing:
    Color correction seems to be an opinion!
    With Aperture (and Canon RAW) with only white balance you will get an image very very close to the result with x-rite calibrated DNG and Adobe Camera Raw, but...
    In both case Colors are very outside of reality!
    Adobe Camera RAW and Canon DPP give other different "crazy opinion" on blues reds and greens, and the only program that I found go very closer to reality seems to be CaptureOne.
    In my tests I've used two 5600°K Bowens lights to take a photo of x-rite passport and I've tried to compare it with the official datasheets from xrite:
    http://xritephoto.com/phproductoverview.aspx?ID=1257&Action=Support&SupportID=5159
