Color properties changes when I power up backlight screen

Hello,
My problem is to increase the brightness of the colors by increasing the power of the backlight of the display (Fn + F7).
Parameters of color in CCC are set to default, with increasing illumination are also sliders set to default.
At the lowest level, the colors of the display are normal.
I have the latest version of the Value Added Package from Toshiba.
I would send photos from the camera, but not much see what's going on, a screenshot is always the good colors.
I do not know what to do, hopeless look the same colors.
Sorry for my bad language.
I'm using google translator.

> My problem is to increase the brightness of the colors by increasing the power of the backlight of the display (Fn + F7).
May I ask what do you want to do exactly or what is the general idea of this color change?
The display backlight can be decreases and increased using the mentioned key combination. This change does not affect the colours but only the brightness.
The low display brightness decreases the power consumption and leads to longer battery working time.
If the notebook is connected to mains (using AC adaptor), its not need to change the display brightness.

  • Macbook pro retina color profile changes when switching from integrated to discrete

    Late 2013 macbook pro retina color profile changes when auto switching from integrated to discrete graphics card. Problem started after updating to 10.9.3

    Same here. Really annoying because I have my screen calibrated for photo editing, which makes it much warmer than the default color profile. A lot of websites cause the graphics cards to switch for a couple of seconds, which causes the profiles to switched back and forth a few times, everytime. Really annoying, and dissapointing to see, considering Apple released like a hundred .3 betas.
    You can use gfxCardStatus to make it stay on one graphics card over the other... Just remember to change it back when you're using a program that actually needs the descrete card.

  • Sudden color temperature change when opening some programs

    I got this sudden color temperature change when I open Photoshop, Maya and a few other games. When I quit the programs the color goes back to normal. It first started happening once a while and I didn't really notice, but now it's become a regular thing... I think it begun after upgrading to Yosemite. It's quite uncomfortable to my eyes but it's bearable. I'm just concerned whether it's a sign for something worse. Please please help!
    I took photos of before and after the color change, basically it becomes much brighter and more blueish.

    Did you ever find a solution for this? It recently started for me too, and it's already getting on my nerves First I thought it was because of dynamically switching the graphics card but unfortunately it happens when I use it on an external monitor only (and thus is locked to the Radeon card)...

  • Color space change when using photoshop elements plug in

    When I select photo and edit with photoshop elements, Aperture makes a copy of the file as expected, but I can see the image color/hue etc. has changed, why?  Is there some setting I am missing?  The color of the image shouldn't change, should it? Just doesn't make sense!

    Where do you see the color change of the copy?
    In the thumbnail or preview before it is send to the external edtor?
    When the image is opened in the external editor?
    Or after it is send back from the editor?
    I do not see any color changes when I use PS CS5; it may help to see a screenshot.

  • Why is the label color not changing when my file is updated?

    I would like the label color to change to white when a file has been updated/changed. Since upgrading to 10.7.2 the file color stays the same. Is there a setting I am missing that will allow the file to go back to white when updated?
    Thanks for any input...

    As far as I know, this is not standard functionality in the Mac OS.  Granted this, some third party application, or a script of something, was making this happen for you. Somehow the system update broke it. If you can figure out what software was giving you this feature, maybe you can update it or re-install it.

  • Color calibration change when opening certain apps in OSX 10.8?

    Hey guys.
    I've noticed something weird when opening certain applications in Mountain Lion. For one thing, whenever I open say Final Cut X, the entire color gamut changes on my display. It doesn't look bad or anything. It's almost like the computer is changing color calibrations... like when you used to be able to select Adobe RGB in the display preferences in OSX 10.6. Anyone know if this is an intentional thing when using pro applications? Because I also notice it when I open up iPhoto and when I start "screen recording" in Quicktime.

    I recently started noticing the same issue after upgrading to Moutain Lion. The screen will change from a warm tone to a cooler bluish tone. I think it has to be a bug, as I've had the MBP for over a year running Snow Leopard and never noticed this. I hope there is a fix on the way as this is no good for editing photos and graphic work.

  • Screen color settings changes when certain software is launched.

    Since today I noticed the screen color settings of my Macbook Pro 17" (beginning 2011 model — Running OSX 10.8.4) is changing when certain software is launched. In this case, Indesign CS6.0 gives a strange blue hue over my screen, but when I check my screen color settings, nothing has changed, everything is set the same as when I don't run the softwares that change my screen color settings. I don't recall changing any settings that could have triggered this action. I didn't change any settings in Indesign CS6.0. I do regularly use CleanMyMac 2 to clean out my computer, maybe this has changed some settings? How can I change this back to normal? Google didn't help me neither.

    Ah right, don;t use laptops much and always forget about that one, good catch. Switching graphics cards would definitely have an effect.
    Just remember with that unchecked you will decrease battery run time so you might want to switch it back on when you are not doing graphics and you are on battery.

  • Why is the font color on the Colorful Tabs changing when I choose a new Personna, when it never did before?

    The font color has always been black and the tabs in color, but now when I choose a different Personna, the font fades and/or turns white, sometimes fuzzy. This has never happened before. I even uninstalled and reinstalled Firefox. Please help.

    Does it help if you disable the Persona Plus extension?

  • Color Temperature changes when playing video via Dell 2713H with iMac

    Hi people,
    I'm having major issues with the above. This happens specifically when video is played, be it via youtube or through VLC or even XBMC.The color temperature of the video just shifts to a cooler blue and then after a while goes back to normal. This does not happen on the monitor of the iMac itself. Otherwise, viewing still photos or browsing the web works okay. It is really very irritating as you don't expect this to be happening.
    I've read that this could be an issue affecting macbooks with the ability to switch between integrated and dedicated video cards, but i can't seem to find any thing suggesting a fix for iMacs. Just so you guys know, it occurs on my macbook pro as well too.
    I'm running mountain lion 10.8.2 on the iMac and connecting the dell u2713h via an displayport to mini displayport cable supplied by Dell. iMac is a late 2009 model.
    If anyone could offer any insights, i'll really appreciate it.
    Thanks
    J

    I found this in another thread and it fixed the same problem for me. Apparently it's a Dell "feature" it detects video and changes the color settings for you... ? On the monitor just disable Display Settings>Smart Video Enhance.

  • What would cause logo colors to change when creating a PDF from an InDesign file?

    Hi,
    My graphic designer has a publication laid out in InDesign. When he creates a PDF file of the book to send to the printer, the colors of our logo on the cover change. Dramatically. The really weird thing is that everything still looks normal on his computer, which is off-site. But when he sends the file to me or the printer, it has the wrong colors. We're all at a loss as to why this is happening. Any ideas?
    Also, I'm just an editor and my experience with InDesign is pretty much limited to making text changes so I'm not well-versed in the lingo. If you could dumb down any advice you may have, it would be greatly appreciated!
    Thanks!
    Shawna

    Shawna, there really isn't realistic hope that anyone could troubleshoot the problem from here with the information you've given. If I was answering your graphic designer, I'd be interrogating him/her about the methods employed all along the way from the logo as a stand-alone file to it's placement in InDesign to the InDesign transparency blend space, possible effects or blend modes applied, and the wide range of possibilities surrounding the methods and settings used in the export/conversion to PDF.

  • Color Swatch changes when opened in Photoshop CC 2014

    I'm not sure if anyone else has encountered this, here is the scenario:
    I create a CMYK color swatch in Kuler and save the swatch, download it as a .ase file, and then load the swatch in Photoshop CC 2014. 
    When the swatch is loaded all of the colors are lighter than the colors in my kuler swatch.
    The below image shows the top kuler swatch, and the colors that were imported once loaded in Photoshop.
    TOP: screenshot of my kuler swatch from the kuler website
    BOTTOM: screenshot of the colors from my swatch once imported into Photoshop CC 2014
    Does anyone know why this is happening and how it can be fixed?
    Thanks!

    That's because color management is different in Kuler and PS.  The good news is that Kuler Panel is now available for PS 2014 at  https://creative.adobe.com/addons/products/2507
    You can directly set active color from this panel or include the whole theme into the swatches panel without change in appearance.

  • Why don't color values change when using proof colors?

    Hi,
    i am very interested in obtaining exact replicas of the image in screen (in ProPhoto) and the image printed (using a suitable printer profile). However when I select Proof Colors from the view menu, the appearance changes but the RGBV or Lab colors remain the same. This is counter intuitive and goes against the well known recomendation to do color correcting using numbers instead of your eyes.
    What's happening? Is there a way to accomplish what I want?
    Thanks,
    Juan

    Juan,
    please let me tell you my opinion, based on working with i1Pro, ProfileMaker and a couple
    of printers and monitors:
    a) one doesn't calibrate a monitor for a better match of monitor view and print result.
    The monitor has to be calibrated for preferred settings, here for 100cd/m² and 6500K.
    In my case, calibrated in an almost dark room in order to avoid any flare, the minimal
    luminance is about 0.3cd/m², which results in a contrast of about 300. With some ambient
    light the actual contrast is probably not as large.
    b) one doesnt calibrate a printer with respect to a monitor. The printer is calibrated by
    printing a target and measuring this, followed by profile generation. As a result, a printer
    can print color patches with certain Lab values with a measurable accuracy, without any
    reference to a monitor. By the way: calibration takes the paper color into account, there-
    for one needs for each paper a new profile (as well for different printing modes or diffferent
    black inks and so on).
    What is to do?
    You have already i1 Profiler. Each version can profile monitors, but you need a version
    which can profile printers as well. In this German doc means Drucker=printer:
    http://www.pdfmarkt.de/index_de,marktcm,15,528,,49.php
    It looks as you have a version which can calibrate printers in RGB mode (perhaps i1 Basic Pro2 ).
    Then follow the procedures in these docs, mainly the third:
    http://www.northlight-images.co.uk/reviews/profiling/i1_profiler_overview.html
    http://www.northlight-images.co.uk/reviews/profiling/i1_profiler_monitor.html
    http://www.northlight-images.co.uk/reviews/profiling/i1_profiler_rgb_print.html
    What means RGB mode? Epson printers, for instance my model 7890, can be calibrated in
    RGB mode or in CMYK mode. Of course. the printer prints finally by CMYK inks, but the
    targets are defined either by RGB values or by CMYK values.
    RGB mode is preferred by photographers (RGB images), CMYK mode accepts as well CMYK
    data as generated in PostScript workflows and is used for proofing offset-print-ready PDFs.
    An example: technical graphics may contain one or two inks in order to avoid registration
    errors. Sending these data to an 'RGB-printer' would result in printing by all inks.
    I'm calibrating in CMYK mode. The profile interpretation by Profile Inspector shows CMYK
    as device space. Available profiles by others (for common papers) show RGB as device space.
    Profile connection space is in either case CIELab.
    How are the viewing conditions?
    Probably not by viewing monitor and print side by side. The monitor has 6500K, prints are
    to be inspected under 5000K. Thus, a simultaneous adaptation is impossible.
    Also, it would be wrong, because the rendering is mostly not Absolute Colorimetric.
    For the critical inspection of prints the illuminance should be very bright, 2000lx (lux),
    according to ISO.  100cd/m² is roughly equivalent to 300lx (3-hundred).
    As a result, one cannot expect a match, but an impression: looks right on the monitor, looks
    right on the print. And an offset printing press can be adjusted by matching a proof print.

  • Font color wont change when creating a proof book

    I have never had any problems changing the font color when creating my proof books and all the sudden I can only get black text. Can anyone help I am in the middle of designing a baby book and
    the design calls for pink and grey text not black.. If I am not mistaken I think I just did an update a week are so ago when the trouble began. Thanks Wezzy

    The photos is the book tray are sorted by date.  So to get them in the order you want you need to do this;
    1 - group them in an album and manually sort in the order you want.
    2 - select all and go to the Photos ➙ Batch Change ➙ Date menu option.
    3 - select a 1 minute time differential between photos and click OK.
    4- add the photos to a book and they will be in the order you need.

  • Color Correction changes when Canvas is re-sized?

    I have an Apple Cinema Display 22 inch (pre-HD model) and am working with some DVCPRO-HD footage that has been turned black and white using the 3-way CC filter. We wanted to do a quick pass on it and get the contrast as consistent as possible before we spend the money going in somewhere with an HD CRT (hopefully) for the final 'contrast tweaks'. My question is this: When the project is arranged in a 'Color Correction' layout, the 'Excess Luma' range check gives us a green check mark on certian clips; however when the canvas is stretched and re-sized to give us a bigger viewing area, we get an 'exclamation point' on the same clips -- even though the dots still look the same (good) in our waveform monitor. Why does re-sizing the canvas -- making it bigger -- violate the range check? That shouldn't bel. Should we just ignore it, and pay attention to the waveform monitor?

    My guess is that when you expand the window, you reveal ALL of the pixels or something, and if the image is at 100%, you should be able to rely on the range checking tool report.

  • Why do colors slightly change when copying from Illustrator to Photoshop?

    I want to copy a object from Illustrator and paste it into a Photoshop document with the same color mode and profile.
    When I use the Eyedropper Tool on the pasted object in Photoshop the color seems to be slightly off.
    Both the Illustrator and the Photoshop document have their Color Mode set to RGB
    Both Applications are using synchronized color settings.
    This also happens when the object is dragged or Placed. It does not happen when copying from Photoshop to Illustrator.
    Could there be a problem with my color management settings? What actually happens to the color information, when it is copied from one application to another?
    Thanks for any help.

    Why the heck are people still using these nonsensical hexadecimal HTML numbers?
    Since some decades we got used to describe RGB values by decimal numbers 0...255.
    Both your value sets are practically the same, but how they were converted from one
    to the other, that requires an investigation, how Adobe workflows are distributed
    between California and Bangalore.
