• Is it possible to know if my screen colors to the correct color temperature

  Is it possible to know if my Macbook Pro display colors to the correct color temperature?

  When I got it, it seemed hot, so I adjusted... .but how do I know if it is now right?

  Hello there, Chris.

  It seems you are trying to determine how much to calibrate the screen on your MacBook Pro. The following Knowledge Base article provides a few strides and the link to do this in the latest version of Mac OS x:

  OS X El Capitan: calibrate your screen

  The colors on your screen can be changed by many factors, such as ambient light, the position and the angle of the screen and the age of the screen. To take these changes into account, you can set your display to show accurate color using calibrator Assistant monitor.

  Calibrate it regularly to ensure accurate color.

  1. Choose the Apple menu > System Preferences, click view, and then click color.
  2. Click calibrator Calibrate.Display wizard guide you through calibrating your monitor, then creates a calibrated color profile. When the display profile is ready, it is automatically assigned in the color profile of your screen.

  Some screens have additional built-in color calibration and precision features. For more information, see the documentation that came with your monitor.

• Satellite A210-109: how to change the color temperature of the display?

  I want to know how to change the color temperature of the screen of my laptop? Theres no option in the ATI catalyst and no toshiba utility, where I can change this? I have the latest installed toshiba display drivers.

  Hello

  you mean the gamma settings? I don't know if the ati drivers are able to do, but you can try the program "powerstrip" (www.download.com/PowerStrip/3000-2086_4-10395724.html), which can change the color and the parameter gamma for graphics cards.

  Just give it a try and you will get your favorite color settings. :)

• Find the color temperature of light source with neutral card

  Hi all;

  I have an adjustable color LED strip that I would get as close as possible to 6700 Kelvin. I hope that I can take pictures of a neutral light card and set the LED color based on temperature/RGB values, I get Lightroom (5.7.1).  Is this possible? If anyone can help with the workflow on how to do it?

  Thank you very much

  I was afraid of that. The numbers only make sense for a radiator of black body like a tungsten light bulb or the Sun, which is a broadband light source. CFLs are generally pretty well made using a series of Phosphors of rare earths that are tuned to human vision and with emissions enough broadband. If you use several sources of monochromatic light as single color LEDs you could not get good numbers. It really depends on the wavelengths of light coming out of the LED. If the color on your camera filters are not the same wavelength of the LED and the sensitivity of three colors of the sensor of the camera is not the same as your eyes, you can get to a situation where your eye perceives neutral colors while the camera sees something completely not neutral. This is from your two raw files. Your illuminated LED Gray card probably looked to the eye, but to the camera, it looked purple. This effect is called Metameric failure and is common if the spectrum of light is very "spicy". This is probably what is happening in your case. You have certainly three narrow band LEDs that you mix. You are really unable to apply the model of the black body of "color temperature" unique to it and then you get strange results you observe. There are index to record high in special colours of the LEDs, which have much wider spectrum light show who have far fewer problems with Metameric failure and that should work for this purpose well.

• I get two of my two cameras difrent color temperature values

  I own a D800 and D810 an and I'll put in values for color temperature of 5 600 K on both devices. I save my photos in RAW files.

  Lightroom is for D800 shots 5 400 K and 6 000 K for the D810 display.

  Renderings for two images from cameras are very, but if I change the temperature of color in an image and Synchronize color in pictures of two temperature settings cameras I get different results: some images are warmer or colder.

  
  

  So if I'm shooting with the same parameters of K in the two cameras, why are the numbers of K in Lightroom different from each other? This makes my workflow very difficult.

  
  

  Thank you in advance for a solution.

  
  

  
  

  Best regards

  The best way to make this type of correction is with Panel to develop fast in the library module. This allows a change in the 'relative' (+ 500 K Temp for example) to a group of images with the same lighting conditions. Jump to the 03:30 minute point in this video tutorial:

  You can also add your vote for this application "preset" ability in the develop module:

• Toggle the color temperature?

  I am in the development and the photos I chose are now displayed as images of color temperature. I can toggle this easily? What did I do not know, if I have to that?

  Thanks for the update.

• My basic lightroom 5.6 Panel changes no absolute color temperature, no clarity without brightness, etc.

  @@been using this LR5.6 for a while, today, when I use it, the base Panel change first the basics of the position's not here, rather just the icon as culture, spotting. for the color temperature. No Kelvin absolute number rather only the sliding bar.  without clarity and vibrance, no white don't adjust, not black to adapt.  any idea? @

  To base Panel, click the window menu and choose panels and make sure Basic is selected from there so that you can see all the options under base Panel.

• Fine color temperature adjustments

  When you use the adjustment brush and the graduated filter in Lightroom 5, I have only occasionally gives me the option of color temperature on the menu drop down. Well, this raises the problem by providing specific adjustments to the mixed-light situations. I never seem to have the option for CR2 or DNG, it is only there occasionally for JPG. Is there a problem with my settings that causes this restiriction?

  Thank you!!

  Maybe you have your Version of process value 2003 or 2010.   The color temperature sliders are available only in PV2012 for the adjustment brush and the graduated filter.

• RE: White Balance and color temperature

  Can we do the same kind of white balance, as we have in Photoshop Camera Raw, in Premiere pro?

  Also, we can change the color temperature in Premiere Pro?

  Thank you.

  Very few cameras RAW video format out of the box –, RED, Arri, BlackMagic.  There are no DSLR that can do it for the video, even if they probably all do for still images.

  That said, I understand that some Canon models can be made to the RAW video format with magic lantern was last updated, but I don't know how well these files would work in PP, as Adobe has no support for them.

• Lightroom 4 changes the color image and the color temperature when I synchronize a folder

  I have this problem every time I synchronize a folder that the images have been added in.

  Example: I have a folder of images in LR; I export all these images with a watermark, resized, etc in a folder separate from the evidence; even though I made this batch using LR for some reason any app still won't see not those images until I sync. When I does not synchronize, it moves to the temperature of + 8 color and hue to-11; I then have to go back and undo this color temp move.

  LR how to stop the evolution of the color temperature of the pictures when syncing?

  DG

  Very well!

  Come to think of it: it is not so surprising after all, because LR remembers the last settings of import as well when you make explicit imports.

  You please mark the topic as resolved by marking my answer the solution as 'correct '?

  Thanks, Cornelia

• Importance of color temperature specific when you create dual-bulb DNG profile

  I have an X-Rite ColorChecker Passport and I would use it to create a profile of double-bulb for my camera (and each combination of lens) for use in LightRoom.

  After extensive research I have persistent questions:

  1) how is it important to nail color temperature. You * must * photograph the ColorChecker under of the Illuminant A and D65, respectively, until the latest Kelvin?

  2) if I nail what precisely, the profile will be less accurate?

  3) if the respective quite accurate color temperatures is indeed important, it's OK to use 2 speedlites diffuse and gummies with Lee/Rosco color correction gels to illuminate the Colorchecker? (The Lee / Rosco gels do not have the exact CTO gel for K of 2850 specified in the Illuminant A DNG specification, but it approximates)

  4) if it will really help accuracy of profile, how do I get hold of the reliable/certified light bulbs that produce the desired color temperatures? (I'm in the United Kingdom)

  Your advice will be greatly appreciated.

  Exact (in Kelvin) color temperatures are not so important within the standard range of daylight (more than 4000 K), because big number change of color temperature is in fact small differences regarding color camera profiles go.

  What is more important (rather than the exact number) is the spectral characteristics of enlightenment. It is not easy to characterize for the end user, but you can think of in terms of type of bulb. Most compact fluorescent lamps are spectrally very different from the true light of day (even if the bulb is shown as 'full range'), for example. My recommendation is to create a profile for the type of lighting you will be sub, rather than trying to match the exact numbers.

• Color temperature of the room. Light falling on your monitor.

  As part of a good color management strategy how big a problem or concern is it about the room temperature of lighting where you work - specifically, the light that falls on your monitor screen that you use to edit and view images.

  For example, I used a sensor to check the light falling on my monitor. He indicated that this light was 3700K color temperature.

  I use a LCD screen.

  Should I try to change my room light somehow. My understanding is that the 5000K range is better?

  Hi, Tom.

  Images on a screen are a little different from that of the images to print.  What you see is reflected in the press, entering your eye, less what is absorbed by the pigments, inks, papers, etc..  If it does not exist in the light source, it can only exist on paper.  Light source definitely affect the colors reflected in your eye.  (of course, the eye adapts and color correct insofar as possible).

  With the monitors, light (LCD, phosphores, etc.) IS the image.  In general, the temperature of your ambient lighting should have less effect on the displayed image, however, the level of ambient lighting can have a big effect.  In addition, it is a good idea to keep the excessive light armored so do you not monitor, which can reduce the contrast, flare, change the dynamic range, etc.  (3700K sounds like a taste of fluorescent, or a mixture of incandescent and fluorescent).

  In an ideal world, your lighting in the room would never vary in color or brightness, temperature would be a perfect D50 and not too bright.  You would also have a perfectly neutral workspace, gray walls, wearing a black shirt, etc.  Then, you can maintain some consistency and use the same lighting to view your prints.  It is not always easy to achieve.  Instead, you can stick with normal room light (not too sharp) and then use standard lamps to view your prints.  That's what a lot of people do if they cannot achieve perfection.  Printing companies even do this and use a look at a stand for an assessment critical.  If your monitor is calibrated correctly, you have moderate ambient light levels, a hooded monitor if you have a standard D50 look at a light with the right intensity and reflection problems, you can get great matches of the print monitor.

  So, I don't sweat the ambient temperature light.  I would try to get moderate ambient light levels.  Then I'd get a lamp Solux 4700 K look at one or a few Philips 5000 K fluorescent fixtures to view your prints.  Try to adjust the intensity of the light falling on a white sheet to be the same approximate brightness as a white document displayed in Photoshop.  They should be relatively close.  Personally, I like to calibrate my monitor 5200K, 2.2 gamma and 90cd/m2.  Works for me.

• LR 6.3 - How to set the color temperature in units of 50?

  Recently updated to 6.3 LR LR 5. In LR 5, I could click on the color temp box and drag left and right to adjust the temperature of color 50 increments of unit. Now, it will sometimes start 50 unit increments, but then if I drag further, it starts to change the setting in random numbers. I know that this is normal behavior for the actual slider, but I would get the 50 backstroke of function setting unit when clicking / sliding on the box color temp. Thanks for any help.

  If you use the upper and down arrows instead of the mouse, the increment is 50.

  If you do the more wide Panel, you get a finer granularity with the mouse, movements, but which removes the space in the picture display.

• How is it LR4 changes the color temperature of the files during import?

  Here's what happens:

  I work with a connected to a card reader Sandisk Sandisk 32 GB card.

  I'm working on a MacBookPro.

  I have the latest Lightroom 4.1

  I start the import of in LR.

  For example, FILE - IMPORT PICTURES AND VIDEOS

  And then I import on my external hard drive.

  The buggles my mind thing: at some point in the import, LR changes the color tempretaure of some of the files!

  Thus, the first 63 first imported images are at the right temperature and then everything else is false.

  I went and open files on the FINDER, and all CF files are at the temperature of accurate color on the card itself.

  So, what the hell is going on?

  If someone saw, I'd love to hear what you have to say.

  Yes, I think that you have changed the default settings - specifically for a certain ISO setting, which is one of the options - (perhaps inadvertently), so change your ISO has triggered the new default value of development. If this isn't what you want, you can restore the default Adobe development settings: use the same image to develop, select develop > set parameters by default from the menu bar, then click on "restore default settings Adobe". This should stop the problem does not happen.
