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.

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....

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??

D3 + "Auto" White Balance in LR2 = +30 Magenta

I have been finding some problems with the "Auto" white balance setting in LR2...
Since I started shooting RAW with my D3 (while still shooting with my D70 in the same locations) LR2 likes to give me a +30 Magenta whenever I choose Auto no matter where or what I'm shooting.
I don't suffer the same adjustment shooting RAW on the D70 (interchanging the same lenses.)
Anybody else seeing this issue? I'm shooting Auto WB on the D3 almost all the time and I end up having to manually perform any WB tweaks in LR otherwise everything is too "pink."

While generally agreeing that a gray-card white-balance measurement is more accurate and eyedropping something that glows in UV light is a problem, in this particular case, if the dress does indeed look white to the eye, and the people that will be viewing and purchasing the pictures expect it to be white, then white-balancing on the dress can be ok.
In this particular instance the issue seems to be that there is mixed lighting between the sky and the trees so the particular part of the dress being eyedropped changes things, and the angle of the gray-card would make a difference, so the multiple angles of fabric in the dress may offer a wider range of "targets" where one is more accurate than the gray-card.
I wish LR would allow the Auto WB to be restricted to the cropped area of a photo, so you could crop it down to just the gray-card or in this case the front of the dress and have it guess more correctly.
The maximum area that can be sampled by the WB-dropper is too small and the area sampled for the Auto WB is too large for LR to be the most helpful in certain situations.
Being able to eyedropper a non-neutral area, such as the skin and compute the color-balance as compared to a library of skin tones, would also be very helpful.
Elements lets you color-balance a photo based on skin tones, and you can do this thing by hand in Photoshop Levels/Curves by referring to RGB values, but I wish LR would be helpful in this regard, as well.
I realize this is what the DNG Profile Converter and Colormunki are letting you do, but having to create a permanent profile and install it and use it are not the same as being able to create an image-specific profile and use it in place of WB across several images.
Why shouldn't I be able to have someone hold up a color-checker and have LR compute an image-specific color-balance based on that.
The other thing LR should allow is have an eyedropper help with determining the highlight and shadow tint hue/sat values.

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).

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

Auto white balance settings?

What does ACR base the Auto White Balance settings on? How does it determine what it thinks it should be? How acuurate does it turn out for you?
Thanks.

How acuurate does it turn out for you?
Useless.

Camera Raw crashes with use of white balance eye dropper.

Using PS CC2014.2.1
Since this update, whenever I use the white balance eyedropper in Camera Raw, if placed over an over exposed region, instead of the dialogue box popping up to warn that the area is too bright, the system just freezes. Have to launch task manager and close PS.
If eyedropper is placed on non-over exposed (not clipped) area, it seems alright. Anyone else experiencing this?

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.

D2X auto white balance handling?

How does Aperture get on with NEFs shot with auto white balance on a D2X? It was a problem in CS2.
And...when I saw the demo at the Nikon show in London, they were running it on a Quad. I loved the ability to zoom in on the thumbnails, but how fast is that on something lowlier than a Quad, like a dual 2.5?
(Thinks: can I go on finding enough queries to hold myself back until the first update?)
Nick

Nick,
I generally shoot in auto white balance and I have not noticed any problems with my D2X images. I actually expected some issues based on all the bashing over the encrypted NEFs with the newer Nikons.
With now just shy of 10,000 images in my library, Aperture runs very nice on my Dual 2.5.

Green colour cast using Cinema DNGs

Hello
I'm shooting RAW with 5D3 and then convertiing to CDNG.
When viewing the footage in Speedgrade I get a huge green colour cast.
See example image: http://i.imgur.com/zQnziZT.jpg
I get this for every CDNG I shoot and even sample CDNGs obtained from the web.
Everything looks fine in DaVinci Resolve or in ACR, but I would prefer to work with Speedgrade as it fits my workflow better.
Obviously I could correct the green cast and balance the RGB parade but I dont want to do this every time.
Anything I can do?
Many thanks

Thank you for the reply.
OK so reading from those threads its 'normal' behaviour - however it isn't helpful, useful or wanted behaviour.
Both DV Resolve and ACR are able to give a usable 'corrected' starting point using the 'as shot' data - Speedgrade should be able to too.
If anyone from Adobe reads this - please condisder this another hat in the ring for this needed feature request.
Thanks

Lightroom seems to auto white balance on RAW files

Hi, I started using Canon RAW files and noted that in Lightroom, it will render a preview and change the original photo colour etc. Is this normal and how to I switch this auto rendering off?
For JPG, it doesn't seems to do that...
Thanks!

When you import, one of the options is "Develop Settings" (the Import Photos dialogue box, below the list of pictures it's going to import, in an area labelled "Information to Apply"). Unless you have something other than "None", then I don't think it alters the WB, though I could be wrong. Of course, if you apply a Develop Setting then all bets are off - the preset could do anything.
As for Auto Tone, go to Edit menu, Preferences, Presets tab, and check (or not, as you prefer) the Apply auto tone adjustments option. But that shouldn't alter white balance or colour.

How to batch process auto white balance

I have 500 RAW photos taken in different lighting situations. How do I batch process these photos so that each photo is individually auto adjusted for white balance. I also have the same question for EXPOSURE.

If you're using Aperture 3.3 or later, you can use "Auto Enhance" to do this, which will attempt to automatically set the white balance, exposure (a mild tweaks), put a curve on the photos, etc. In general, I find it provides a pretty good starting point.
You can do it as an import preset. OR, you can select all the photos you want to edit, then choose Photos->Add Effect->Quick Fixes->Auto Enhance.
If you don't like it you can go through Photos again to remove all adjustments.
Auto enhance is pretty neat; it has 4 or 5 things it does. You could define your own preset that did ONLY white balance and exposure if you wanted as an import preset.
Note you have to do it through the menu at top. If you do it from effects on the left it will only apply to a single photo.

Color correcting auto white balance footage

I shot some video yesterday and at the time of the shoot, I made sure to set my white balance, however after looking at the footage I notice the color temperature slightly shifts constantly. I don't know why this happened, but it's too late to investigate, my project is due in less than a week.
The good news is that I've realized that that there's a white object in the bg of the shot the entire time that is pure white so i could color correct by setting that as the white point in FCP. The only problem is that since it shifts every 3 seconds or so i would have to keyframe a LOT. Is there any plug-in or application that will let me track that white object in the background so it can set a custom white points for every frame?
Running Final Cut Pro 6.0.2
PS: I found Avid has auto color correction -- basically what I'm looking for I guess. Unfortunately I don't have Avid.

there's no auto color correction feature directly in FCP
there are 3rd party plugs to allow you to track objects but i'm not aware of any way to link that to a color correction

RC 3.3 Auto White balance

When I pick a target neutral (using the eye dropper, white balance in the deveopment section) the RGB values flash on and off.
I'm running windows7. I've not noticed this in any previous version of lightroom.

Known bug.
