White balance adjustment

When selecting neutral gray target with the white balance tool, are RGB readings on the loupe averaged values according to the scale of the loupe? Then, is the white balance adjustment made with this tool averaged for the pixels under the loupe?

You can test it for yourself.
Zoom in on a portion of the picture.
Hit W to get the white balance tool.
Click on a spot to obtain WB
Hit W again (unless you have autodismiss set other wise)
Use your scroll wheel on your mouse to change the loupe size and click again on the same pixel.
The WB changes a bit each time.

  • Local white balance adjustment tool

    I really like the new local white balance adjustment tool. If I could change something will be to give a real color temperature to the tool instead of a number from -100 to 100. Let me give you an example of how I used it today.
    I forgot to bring some gels for my flashes for a photo shoot. I was using the flashes to illuminate the foreground and I had fluorescent lightening on the background. It was the perfect opportunity to try the new tool. I knew exactly what the color temperature for both front and back were. I applied the background color temperature of 3200k to the picture and when to locally change the foreground. At this point I was guessing what it should be at. My monitor is color calibrated but I was under fluorescent lights with my laptop. Instead I could have added +2200k or dialed 5500k to the local adjustment tool.
    Please let me know if you need more information.

    I'm sorry I found another discussion about this topic already. Shame on me I didn't do a more thorough search on it before.

  • White Balance Adjustment question

    I have about 800 images from a wedding, and am now ready to go thru them and adjust the white balance.
    However, am I missing something?
    I click on the white balance option, then the dropper, then click on the image to adjust the white balance ...
    But, when I go to the next image, I have to THEN click on white balance AGAIN then the dropper, then the image etc etc etc???!!!
    Can I just click on the dropper once, then scroll thru the images to adjust without having to ACTIVATE the white balance option again and again and again?
    When there are 800 images, adding in those extra two steps is slowing me down big time.
    Does this make sense?
    Much appreciated!

    So, I wanted to adjust each image individually but
    without always having to click on White Balance
    Adjustment each and every time. I really just want
    to click thru and eye dropper the images.
    Is this possible, or do I have to always go to the
    adjustment pane and let the thing know I want white
    balance adjustment after each image ...
    I'm afraid the interface lets you down here. What's unfortunate is that there is no keyboard shortcut for the WB tool. There is for Edge Sharpen, for instance (ctrl-S) -- which means that for each image you can leave the HUD open and very quickly bring in the tool so its standard preset will be applied. It would be awfully nice to have that fast, mouseless capability with other tools.
    (Query: since you can't get rid of default tools, which is why they're grayed out in the "+" menu on the HUD, why do they have keyboard shortcuts?? Pressing the shortcut doesn't toggle the tool off-and-on, or anything. Why do Color and Highlights & Shadows have ctrl-key shortcuts, and Crop and Straighten have non-ctrl-key shortcuts? Mysteries, mysteries.)
    It might be most efficient to figure out what most images need, lift and stamp that setting, then go back and nudge or cancel the WB correction on the others. Depending on the numbers and proportion, of course.

  • Where is the white balance adjustment?

    The iPhoto app provided an adjustment for white balance, if Photos in ios8 is a major update and replaces iPhoto, where do I find the white balance adjustment?

    Do you just have to eyeball the correct adjustment rather than have it done autmatically?

    I am on Lightroom 5 and the exposure and white balance adjustment tools on the right side of the screen have disappeared.  How do I restore them?

    Right click on one of the other panel headers e.g Tone Curve and a menu will pop up for you to select Basic.
    How it gets de-selected is not apparent but several users have had this happen since the release of version 5. It has ahppened to me on at least two occasions.

  • Please add white balance adjustment to brush tool!!

    Please add to the brush tool the ability to adjust white balance.  I know you can currently paint a color over areas, but I would like to see a true white balance control in a brush.  This would be quite useful for wedding or event photographers who shoot quickly in varied lighting often without flash.

    More specifically, I would like to paint at 5500k or 3500k or whatever color temp I choose, measure, detect, or feel so inclined to.  Like I said before, I realize the paint with tint works, but painting a white balance would be much easier.  I never mentioned accurate.  Accurate photographs in mixed lighting usually look bad (especially when you mix in fluorescent).  My clients don't want "accurate" photos, they want what they remembered the event to look like.  I don't feel the need to suggest the current features fail in any way to make a suggested improvement upon those features.  The current (LR2) demosiac engine works well, but LR3 got an overhaul.  Was demosiac in LR1 and LR2 a failure?  I believe my suggestion is consistent with the intent of LR.  While painting a warming or cooling color would certainly achieve the desired results, painting a preset color balance or manual temp/tint would be quicker.  It makes for a better workflow.

  • White Balance Adjustment in Preview?

    I'm pretty sure that, a while ago (pre-Leopard), it was possible to adjust a picture's white balance in Preview.app. Now that feature seems to have been turned off. Or am I seeing things? What's going on?

    You can test it for yourself.
    Zoom in on a portion of the picture.

  • Mass unset an adjustment (white balance), aperture 3

    Hi all,
    I upgraded to Aperture 3 and everything went smoothly, even the library upgrade.
    Except for a small adjustment thing: After "reprocess masters" every image I had white balance set manually (most of my tens of thousands of images), looks now green. Not only slightly, everything is green. When I unclick the white balance adjustment, the picture returns to pretty much what I expected it to be (camera is Canon 5D, raw images).
    Seems that Aperture 3 processes this generally better and pictures look fine without adjusting white balance.
    Now the question is: how do I mass unset white balance setting for each and every image inside a project? With lift and stamp I can change white balance, but I didn't find a way to unset it completely. Manually I can uncheck the box before white balance and that does the trick, but I don't plan to click 42000 images manually.
    Is there a way to batch change this? It would be easier to just unset everything, then go through the previews quickly to see if some of the photos need WB adjustment and do those few manually. I've now gone through five projects manually and have left the manual adjustment to only about ten photos with a slight modification towards purple.

    Yes 5D can do that but I don't use the feature.
    These are albums created ages ago with first Aperture 1 and then Aperture 2 for the newer ones. Actually, this pointed me to the right direction.
    The greenness problem seems to trouble only old photos processed with Aperture 1.0 or 1.1 RAW settings. I've been processing the oldest albums first and didn't even think about this.
    For 2.x photos, the reprosessing doesn't cause any greenness or other problems, and also, curiously, the "stamp default from jpg" trick works for these images just as suggested here, in case I wanted to remove the WB settings, which seems to be unnecessary.
    But for 1.x raw processed photos, there is a desperate need to do something and the lift & stamp trick doesn't work.
    Weird, but the problem seems to be in the fact that I never converted anything when I migrated to Aperture 2. There was no need to do anything so I just let the old ones be as they were. I tested moving to 2.0 raw with a couple of photos and I wasn't happy with the result as something in the colours and/or white balance changed and some minor adjustments would have been needed.
    So thanks for your help and ideas once again. I'll leave the old ones for now as they are and hope Apple fixes this. They obviously haven't tested the migration at all with a library containing photos processed with the ancient 1.0 raw processing.

  • How to apply white balance from jpeg to raw version

    I always shoot in RAW + jpeg format.  Many times the jpeg will work fine and I still have the RAW if I want to take the time to tweak things a bit more.
    But sometimes the jpeg stumbles on a white balance that works well for a particular image.  If I want to apply that same balance to the RAW version, I would like to be able to read what that color balance setting (in K degrees I assume) is so I can copy it.
    Is there a way to find that info somewhere?  The exif will only give you the name of the setting (Flash, Auto, Cloudy, whatever...) but not the numerical info needed to apply it in Aperture's White balance adjustment.
    I use a Nikon D600.
    Thanks very much for any info!
    Bo

    OK, progress!
    I found out from Iliah Borg on the dpreview.com forum that the utility ExifTool (or its GUI version pyExifToolGUI) will provide the R, B, G1 and G2 values for the white balance setting.  They are provided as multipliers or absolute vaules.  Example:
    WB RB Levels : 1.51953125 1.8515625 1 1
    WB GRBG Levels : 256 389 474 256
    Now does anyone know how you can enter these type of numberic values in Aperture?  The standard White Balance brick does not have input fileds for these types.

  • 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?

  • Aperture white balance default

    I'm new to Aperture
    The Aperture white balance default is 6826 (tint 13).
    I set my camera wb to Flash.
    How can I change the Aperture default WB to Flash?
    In my meta data all my images have a wb=Flash. Should Aperture read the metadata to set the WB?
    Tony

    Hello Tony,
    welcome to the Aperture Forum of the Apple Support Communities. Can you explain a little bit more, which default setting you are talking about?
    At first I thought you were talking about the default setting for the White Balance adjustment in the adjustment panel of the Library inspector. But that one is set to a color temperature of 5000K (Horizon daylight), a suitable preset for landscape photography - at least, that setting is what I see in my Aperture version.
    The number you quote "6826 K" is in the range of the color temperature of a LCD or CRT screen, suitable for the display of digital images on a screen. Where did you find that setting?
    If you want to adjust any image to the setting the white balance your camera was set to, then you need to define a preset for the White Balance adjustment in the adjustment panel of the Library Inspector. Set this to the color temperature of your flashlight - it should be somewhere in the range of 5,500–6,000 K. Do you know the exact color temperature for the flash setting of your camera?
    Regards

  • Aperture: White Balance in Adjustments inspector no longer appears by default

    Aperture 3.3.2
    In the past week, the White Balance adjustment in the Adjustments inspector no longer appears by default in my program. It's always been there, above Exposure, Enhance, and Highlights and Shadows.
    Now, White Balance is gone, and I have to click 'add adjustment... White Balance' for every single photo, which is hugely frustrating. I shoot in Canon RAW.
    What happened to my default White Balance, and can someone help me put it back?
    Thanks!

    Click the cogwheel beside the White Balance adjustment and add this adjustment to the default set.
    Regards

  • White balance, colour temperature value.

    Hi all,
    I've spent some time recently looking at the temperature value in the white balance adjustment for a selection of my pictures in Aperture.
    All of my pictures are taken outdoors in natural daylight. I've noticed the colour value of my RAW pictures in Aperture varies. Is this value recorded by the camera when it takes the picture or is it a value that Aperture works out depending on the colours it sees in the picture?
    For example for one set of outdoor pictures I took in the space of about 30mins the temperature value varies from 4685K to over 5000K and yet as I remember the apparent ambient temperature and light didn't change.
    I usually have the white balance on my camera set to auto but am I correct in thinking that since I shoot in RAW mode the white balance setting will have no affect on the RAW file produced and will only affect the accompanying jpeg? Or is the current white balance setting recorded to the RAW file but without adjusting the picture data and this is the value we see as the temperature in Aperture? Hence if I've got the camera set to auto WB and one moment the camera thinks it's sunny when I take a picture and the next time it thinks it's cloudy then the raw files are recorded with a different colour temperature?
    Regards,
    Dave.

    You have almost got it correct.
    Jpeg will have the WB as per the camera setting.
    The raw file does not have a WB setting. Aperture makes a rough assessment in much the same way your camera does.
    Nothing gets recorded to the raw file only the information from sensor.
    In camera, to produce the jpeg, the processor looks at blocks of data & applies an average value to the block. Lets say there is a block of 8 pixels with 8 different values, the jpeg file format gives it 1. So were you had 8 shades in the raw file you now have one in the jpeg.
    Unless you have a specific need to import both, Aperture can make all the jpegs you want, any size and better quality and easier than you can in camera.

  • Pentax K5 / Apple Aperture - White Balance Inconsistency

    Used my new Pentax K5 with studio flash for the first time on Saturday. I got some peculiar colour temperature results. Can anyone explain this?
    All shots used the following settings:
    - Raw DNG
    - Adobe RGB
    - Camera white balance set to "Flash"
    - ISO 100
    - 1/180s
    - f/11 to f/19
    - same lens used throughout ( Pentax A 50mm macro f2.8 )
    When I loaded the raw files in to Apple Aperture the colour temperatures of the raw conversions came out as an inconsistent variety of temperatures and tints. As sample, the first ten shots on the "roll" show the following white balance values after raw conversion (prior to any manual adjustments being made):
    5759 K / +4
    5759 K / +4
    5759 K / +4
    5759 K / +4
    4492 K / -9
    4479 K / -7
    4463 K/ -8
    4469 K / -11
    4563 K / -8
    4572 K / -8
    (For what its worth, 5759 K / +4 looks right to me.)
    What is going on? Do I have a camera problem or an Aperture raw conversion problem?

    My first question is why are you converting to DNG before importing into Aperture? It appears that Aperture should support the RAW files from that camera.
    Second question is how familiar are you with the whole concept of RAW images?  You realize that none of the camera settings (apart from shutter speed and aperture) affect the digital RAW file. 
    One of the strengths and reasons for shooting RAW is the ability to adjust white balance after the shoot. JPG images are extremely limited in their ability to have there white balance adjusted.
    RAW conversion software is as much art as science, which is why no two RAW conversion programs will render an image in exactly the same way.
    So I would first eliminate the DNG step and then see how that affects the workflow.
    regards

  • Aperture 3 White Balance range

    I recently took a handful of photos under some garishly unbalanced street lights. I took a greycard shot and used custom white balance in my Canon camera, which caused the photos to come out surprisingly well but not perfect.
    When I loaded the photos up in Aperture, I thought that two or three pictures could use some additional tweaking. By making any white balance adjustment at all in the application, it reset the white balance to 2000K -- which is actually above the temperature of the lights.
    I can't seem to manually set the white balance to any lower value, and the only way I can get rid of a color cast is to disable any White Balance adjustment (thus using the setting from the RAW file).
    Is there any way to extend the range of Aperture's white balance adjustments? Is this the sort of thing that ought to work its way into a feature request?
    (Just for conversation's sake, the location in question was the Campbell Community Center's parking lot during a San Jose Bike Party. Anyone from the Aperture team is welcome to take some snapshots there if they doubt the necessity of a wider white balance range...)

    Have you tried tweaking it with the curves adjustment? Sometimes you correct colour casts a bit more precisely with a simple "auto split" curves adjustment, or by tweaking the curves themselves manually.
    Have a look in the manual starting at p536 and also check out p549 specifically.
