Turn off auto white balance on USB camera

Hi,
I'm using a USB camera to capture images of bright colored lights. I have the light configured and working in MAX and Labview 2009. My problem is that the camera is set to auto white balance in MAX and Labview, and I can't seem to change this to no white balance. When the bright lights are imaged the white wall behind the light turns the complimentary color to the light as the software attempts to 'white balance' the entire image. There doesn't seem to be an option in Labview or MAX to turn this white balance to anything other than 'auto.' I've attached the program and a couple screen shots to show the problem.
Any help would be appreciated!

Hi!
This might be late, but for the sake of reference I will answer anyway.
You should use 2 property nodes.
To the porpery: "CameraAttributes->ActiveAttribute"
you should wire the string: "CameraAttributes::WhiteBalance::Mode", and to the property "ValueDBL" you should wire 1 (for manual).
Then repeat this on a second property node but change "mode" to "value" and wire the desired value to "ValueDBL."
For a more complete description see my post on a similar problem with autofocus (change "Focus" to "WhiteBalance" and it is the same as described above).

  • How can I turn off Automatic White Balance/Correction?

    Hi,
    I shoot color Infra-Red images. White Balance is handled in Camera - and then in Photoshop. As a new user to Lightroom 2 - everytime I view/click on an image in the Library - the color/balance of the image changes to a deep red, and I lose all of the vivid colors that I had from the original image. The files are Nikon NEF RAW - and I am looking for a way to turn this automatic change in colors off. Can anyone help?
    Thanks and have a great weekend !!!

    Hal,
    I have a Nikon D-70 that has the Lifepixel infra-red conversion. Take a look at their website and you can see the great color infra-red pictures that you can take with this converted camera. So there is my problem - I can set the camera at a PRE White-Balance and shoot Cyan/Blue/Green photos - and then import them into Lightroom. I see the photos in the Library - but as I click on them to view them, they change color to Red. Now if I set up the camera to take White Balance as Auto - or pretty much anything else other than the PRE (for which I can adjust), I will also get a Red photo. Red is OK if you want to convert to B+W - but if you want to retain all of the colors, I need to keep the color that the camera shot - without Lightroom changing them. I looked at the history - and only have an import/date. Other than clicking on it to view - no changes have been applied by me - yet. I will try to shoot them as jpg's - the ones I am working with right now were shot in the summer. We have -20 Deg. C. here right now - so Infra Red camera is in bag - have no green leaves to shoot. Looking through preferences and settings to see if I can find a "turn-off"....... Actually - let me load the photos with Bridge and see what they look like there..........

  • Lightroom: Why does auto white balance no longer work after changing the camera calibration profile?

    I'm using NEF raw files from Nikon.
    Lets say for example I import a NEF file into Lightroom (v4) and click on 'auto' for white balance. The white balance in the image is  adjusted correctly (somewhat). However, if I then change the camera profile (in the camera calibration section) from 'adobe standard' to 'camera standard' then the white balance in the image becomes very wrong. I then have to set the white balance back to 'as shot' and correct it manually instead.
    Why would 'auto white balance' no longer work just because I change the profile from 'adobe standard' to 'camera standard'?
    Any ideas?

    Works as expected here...
    Which Lr version and what OS??

  • Lightroom 2 - Auto white balance - crash

    I'm having intermittent problems while applying auto white balance on some CR2 files in Lightroom 2 running on OS X 10.5.4. When choosing Auto from the list of white balance options, LR waits for a second or two, doesn't update the history panel and the spinning beachball appears. CPU rises to about 100% and there's no other way than to force quit.
    So far it happens with, say, one in 50 images (I've been working on approximately 100 images and with 2 this happened).
    When I restart I can easily recreate the problem by going through the same routine.
    The workaround is working on another image and then going back to the problematic one; then I can apply AWB without any problems.
    I can save a (lengthy) hang reporter log file.

    Thought I was doing pretty good with LR2, but unfortunately this problem has showed up on my Mac OS X 10.5.4 system. The stalls (i.e., beachball) are when developing CR2 images from a Canon 5D. I experience many occurrences of the problem when going through this folder of RAWs, perhaps 20-30% of the images. Today I thought I had found one that always fails, but turns out not to be the case, although it causes a failure over half the time it is accessed. Same symptoms as described in the above posts: Convert an image's white balance to auto, in either quick-develop or develop. Then when you access the image you get the spinning beachball forever, and have to force-quit. I've also stalled LR with this sequence: in QD, convert WB to auto, switch to develop module, undo the WB change in history by clicking the prior step... LR stalls. Basically I've seen all the same steps as described here, and more.
    Also, just for fun I tried everyone's favorite troubleshooting step, i.e., trashing preferences. It made absolutely no difference. The first time I simply clicked on the troublesome image, LR got stuck.
    Jao... interestingly, I never saw this problem in the beta in spite of developing many, many images in the beta. If it was known and not fixed, that's quite a concern.

  • Colour cast using auto White Balance in ACR 7.4

    I am experiencing a yellowish colour cast when I set the White Balance to Auto in Adobe Camera Raw. This happens with pictures taken with the Nikon D7100 and also the Nikon D50.
    Here is an example,
    White Balance set to "As Shot":
    White Balance set to "Auto":

    So I would conclude the ACR auto wb process is apparently not as reliable as the camera determination, and certainly inferior to direct measurement on a neutral object.
    Oh, Auto WB is reliable for what it was designed to do...take the image colors into consideration when determining the auto white balance. It's doing exactly what it's supposted to do...the fact that it's often not what you want shouldn't be a surprise. The way a camera determines WB is by using a WB sensor (either the sensor itself or an external sensor) which is much more accurate than measuring image colors after capture. I've seen Auto WB help in certain cases where there simply is not white neutral in which to measure but I've found manually adjusting WB the best solution in most cases.

  • Quick Help Please!!!!... White balance 6 HD Cameras

    Hey guys/gals (I only have 2 hours before I ship out)... I have an important gig tonight shooting a live event. I have 6 cameras all at different distances to the stage. The stage is reasonable and evenly lit. How should I white balance all of these cameras (Sony FX-1s and Z1Us)?
    I want to use the manual White Balance in the cameras so they all have the same color temperature instead of 'auto' mode? What I realized today (which I hope I'm wrong) is that I'll have these cameras set up at different distances, they will all have to zoom in at different focal lengths (which effects the f-stops as well) to reach the White Card on the stage for the Manual White Balance. Should I White Balance the cameras this way? Will all the cameras have a slightly different White Blance due to the different Focal length?
    Or should I place all of them in the same spot in front of the stage, go Wide (or tight), and then White Balance all of the cameras at the same focal length and angle?
    2 cameras will have a tight shot all night, 2 cameras will be a tight to medium shot and the last 2 will be medium to wide.
    Sorry if I'm overreacting (slap me if so please), it's an important gig to me and the first time I did this gig over a year ago I had to do a big of color correction depending on the shot/camera.
    Thanks for your time.
    -Monty
    P.S. - I have a set of Warm Cards and a huge white posterboard for the White Balance and the stage is all Tungsten Lighting... basically a crapload of floodlights... theatre setting, no spotlights.

    Good on ya for taking the time to learn to do this beforehand but I may have done some testing first.

    Probably not although you'll have a flare imbalance between the cameras due to the different focal lengths. No two cameras, not even the same model, will ever white balance exactly like the other, there will always be minute differences. You will also want to black balance all your cameras as well.
    However, white/black balance is a small part of the imaging pie. In reality you'd really want to chart these cameras with a [DSC Labs Chrome do Monde|http://www.dsclabs.com/chromadumonde.htm] as a simple white balance will not address differences in flare/gamma balance, or inequities in the white clipper channels. When you chart a camera you null out all the variances in the r,g,b channels which creates a better white balance over all.
    The color section of the Chrome du Monde helps match the color matrices of your video cameras, something else a simple white/black balance will not do.
    Good luck.

  • Pentax K-3 multi auto white balance

    Raw images from the Pentax K-3 with the setting "multi auto white balance" activated have a green color cast when processed in Adobe camera raw (left), Pentax's own Silkypix converter get's the images right (on the right).
    Any chance that in the future multi auto white balance will be supported?

    Thanks for that! I should have been the wiser photographer before I decided to use this new feature. I've got 8000+ images with multi auto white balance enabled from last trip....

  • How do i turn off auto update for mountain lion OS?

    Today my computer informed me it was going to perform an update and restart my computer.  This is a first for me with Apple products. 
    Does anyone know how to turn off auto-update?  When installing the software i ticked the box that disallowed auto-update but i must have missed doing it some other place in the upgrade process.
    Thank you.

    Your Mac will never force you to update.  WRONG.
    When I updated to the latest software updates... I was asked if I would like automatic updates.
    Unfortunately, I pressed Yes.
    Now, I'm in the middle of working on something and my display goes bright white... then I get a message that says "Installing Software Update"... then the display goes bright white... the computer turns off and I need to sign on again.
    AND I can't find a way to turn off automatic software updates!

  • Issues with White Balance and other camera setting...

    I have found a glitch with the camera on the Lumia 800: When you try to change a different white balance setting- (try it with incandescent so you can see the difference) as well as changing the scene (ie to portrait mode) it will flip back to auto white balance, although it will say that it is still incandescent.  If you change the scene first and then the white balance and save those settings, it will take one picture like that and then revert back to auto white balance again for the next shot, but again it will tell you that it is still incandescent. (You can clearly see the white balance difference between the 2 shots, even though the camera settings say they should be the same). The whole point of saving settings is so that you can take multple shots with the same settings.  I have spent hours on the phone to Nokia trying to explain this to them and they have assured me that it will be fixed in the next update.  I took the phone back to the Orange shop and we tried 3 different handsets and they all had the same problem.
    I also have the same problem with video autofocus that  lots of people have mentioned.  Has anyone found a solution yet?  The main reason I got this phone (only last week) was for the camera so I am diappointed.  I am a photographer so I am really fussy about cameras!  They have said in the Orange shop that I can change the Lumia for another phone, such as a Galaxy S2, which is also an awesome phone.  The thing is, I really love the Lumia otherwise.  I really like the fact that I don't have an iPhone anymore, for a start!!
     Does anyone think the network you are on makes a difference? It's just that several people have suggested that there could be a conflict with the Orange software and the Nokia/Windows software.  Does anyone else have this problem who is not with Orange?

    Thanks for all of your valuable suggestions.
    The problem was compounded when there were drastic shifts in the levels of ambient light also occuring at the same time.
    Happy Holidays to everyone.

  • Unsatisfactory E71 auto white balance, blue/purple...

    The E71's camera doesn't really shine with regard to automatic white balance. There's almost always some blue to purple tint. It seems to depend whether the "flash" was used and whether the camera is used in day or "night" mode. The other (non-auto) white balance modes usually don't match the actual lighting conditions too. Is it a deficient white-balance algorithm or is this tint just from the heavy noise in non-night mode? Is there any workaround (on the phone, not postprocessing on a PC) or fix, maybe it is improved in 200.x firmware? - Kolja

    Here:
    fw: 200.x
    Start camera as normal
    before capturing any picture,  set white balance to day light and press Ok
    After that set it back to automatic
    Purple tint is gone
    You must do it after capturing
    Nokia's guys please fix it

  • How do I turn off auto split in iPhoto ?

    How do I turn off auto split in iPhoto? I have about 8,000 old photos I would like to import but it splits them in to loads of events. Would just like to leave them in year folders.

    First try, if importing a sample folder with two images with different days, more than a week apart, will import them as only one event on your mac and  the autosplit is behaving the same for you as for me.
    May be I will have to do it folder by folder which will take for ever.
    Would it be possible for you to join some of the folders before importing?
    Or join your events in iPhoto after importing. Creating yearly events is fairly simple (tested in iPhoto 9.5.1)
    Create a smart album for each year (File > New ) with the smart rule "Date is in the range ...."
    Then select all photos in this smart album and use the command from the "events" menu "create event". This will collect all photos in a new yearly event.
