Blue tint to the screen

• Blue tint to the exported images from LR 2.4

  A particular image, that I exported from LR appears slightly more blue than it does in the LR library. At first I thought it's maybe because I export from a raw image in sRGB and downsizing a lot, but this isn't the cause.

  If I take the image of LR and EDIT in PHOTOSHOP CS3 using TIFF 16 bits and ProPhoto and then in Photoshop manually reduce 640 pixels on its longest side, change it to 8 bits per channel and ProPhoto convert to sRGB, the resulting image is not this blue tint and, in my view, exactly looks the same as the view from LR library. But if I ask LR for export in a 8-bit sRGB TIFF and reduce the size of 640 pixels, with no job of sharpening, the result has the blue tint.

  I have attached a screenshot with LR in the background and two windows photoshop: the left one is photoshop glancing tiff that LR exported; the right is Photoshop showing the same image will be created manually as described in my second para. I find that one on the left has a bluish tint, particularly in the foliage over the arms of the shovel. Flicking between the two windows photoshop, the histogram is clearly more blue in the left.

  Of course, you can say well, "Photoshop isn't Lightroom, so there are small differences. I accept it. But the fact is that Photoshop agrees with LR, this is just EXPORT from LR service that produces a result that is more blue.

  No idea why this should be so? (I have not noticed this on other images)

  I find that quite strange for sRGB, BTW, because the color is the smallest space the most important, one might think, to have the perception during the conversion in it.

  It has historical reasons. When sRGB was designed none of this really existed yet. Recently the ICC made a new sRGB version which has no perceptual intent. You can use it in Photoshop, but strangely, Lightroom doesn't know how to use it.

  When you refer to the scale, I'm not sure what you mean. Do you mean the alteration of color that occurs when mapping range of one color space to another? Sorry, I don't know anything about. But what at first glance seems odd is that why should the color of a pixel mapping be in any way affected by the values of adjacent pixels? (I guess this must be the case for effect "in areas with a lot of detail", as you suggest.

  I refer to the reduction of scale to 640 pixels wide that you do. It is very simply with an average value of the pixels within a zone to arrive at a new image of low resolution. For example, if your original is 3000 pixels wide, and you go to 500 pixels wide, you are averaging an area of 6 x 6 pixels (i.e. 36 pixels) for a single pixel value in the new image. In practice several different algorithms are used to do this, but the basic principle is the same. Lightroom evolves in a linear space, which means that the brightness (luminance) is a linear function of the values bit. This translates into the luminance of the final pixel being correct anything. Photoshop scales in the gamma corrected space of the profile document (gamma 1.8 for prophotoRGB and approximately 2.2 to sRGB). Gamma means that the lightness of a pixel is dependent on the value of bit powerlaw. This translates into the luminance is not always correct with the end result. Whether move you in linear space or corrected gamma issues only when you have lots of small details. Course, when you have a plan of color, no matter that you will come to the same value. However, if you have a lot of edges, there are an error of scale to gamma corrected space. This is detailed in a page I found a quick google here: http://www.4p8.com/eric.brasseur/gamma.html

  So scaling in linear space is preferable from the point of view correct color. However, it leads to the desaturation and maybe look less good.

  A second point that I would put to LR is this: no matter how you do this scaling, why you cannot export a file that resembles that on my screen of LR? The fact that they are different certainly suggests that LR does not use this linear gamma of scale displaying the pictures, then we could add "look, do go and stick to it; don't chop and move one feature from LR to another. »

  Here, you have run in one of the many peculiarities of Lightroom. Because it is made of the jpeg extracted in adobeRGB (in general), the scaling of the display in libraries and other is in a gamma corrected space and so resemble the Photoshop scale. To the point, there is no scale is done, but the view zoomed on is a rendering that is similar to using nearest neighbor scaling. For reasons of speed, it only displays a subset of the pixels. So, with an average of pixels is made. In addition, any color and sharpness noise reduction is applied in the zoomed view on. This means that the zoomed view on developing countries is often saturated. This can be a real problem. There are many images where this leads to completely wrong impression in the zoomed view on. An example would be an image of Christmas lights that will look very colorful with zoom out but when zoom you 1:1 (or go to the library) they lose all color because the color noise reduction, which is then applied. Sea of flowers in the grass, light neon, colored fabrics, etc., are other examples. If you have a lot of microdetail, only display that's really right in Lightroom to develop is the view of 1:1. This is largely fixed in LR 3 BTW, where he restores to a larger size, including the reduction of noise and sharpening and then further reduced to develop.

  I realize that you are not responsible for the LR... no bad vibes intended

  Not bad actually. I love Lightroom, but realize that there are many gaps. In my work, I do a lot of scientific image processing and I'm always curious to see how things are really make.

• On my ipad3 I rectangles blue moving around the screen. Momentarily switches to an article before moving on. Very irritating

  I have an iPad 3. Model MC707B/A. Version 9.3.2 (13F69).

  Blue rectangles are continually moving around the screen from one section to the other. Also a blue stripe sometimes crosses the screen. Has started yesterday for no apparent reason.

  I have tried rebooting with no luck. Helpline Apple could suggest only reset to factory settings. Does anyone have a less radical solution?

  This is one of the accessibility features. It's the switch command. You will need to go into settings > general > accessibility > switch control and turn it off. It is possible, that's what the setting is triple clicking the home button. Try triple clicking again and see if that if he stops, otherwise, use the road that I explained earlier.

• Satellite Pro L300 - external monitor has a yellow tint to the screen

  I have connected a new external monitor to my Sat Pro L300 and the monitor of the station has a strong tinge of yellow to the display.
  I have tried with other monitors and cables and they do the same screen that is yellow.

  Can anyone suggest what I can do, I tried to change all the color settings, but they don't get rid of the yellow tint.
  Thank you.

  Well, maybe this problem is related to the failure of hardware since will have to show common colors without changing the settings in the color settings in the graphics card Control Panel

  In my opinion this s hardware problem
  However, before I ask a technician for advice I recommend updated the BIOS and reinstall the graphics driver.

• No icon of the user name click on the blue paper in the screen that says "To begin, click on user name"... There is nothing to click! It was working fine yesterday, and today the icon has disappeared.

  Hello!

  When I start my computer, I got the blue screen where I can usually click on the leave me in my office.  Unfortunately, this icon has disappeared and I can't log my computer.  The user name was not protected before.  Is there something I can do to get the icon back so that I can connect to my computer?  I tried to restart the computer in safe mode, but it brings me just to the same screen with a larger font.

  When I hit Ctrl-alt-delete twice, I have a username but none of the passwords that I get home from work.  Is there a defect that I can use?

  Thoughts?  Thanks much for any help you can give!

  Then, it seems that your connection files are broken, perhaps because of the infection. What has changed between the time where things worked and the time, they did not? There are ways to fix broken logons, but much depends on what caused the problem. If the machine was in the store I boot with a special rescue CD and take a look, but you can't do it at home. Since you have XP, a Bart PE could help. Otherwise you should take your computer to a local professional. Do not use a type of BigComputerStore/GeekSquad of the place.

• HP G60 screen works not properly, a blue tint on it

  Hello everyone, I hope I can get help with this on my laptop because it has a weird blue tint that has appeared on the screen when a friend knocked at the back of my screen with a wooden mallet.

  The tint still allows me to work it's just boring.

  If I turn the screen at an angle, it turns back to normal

  I have reason to believe that it is a hardware problem or something wrong with a backlight.

  The graphic card works fine (I can play Starcraft II, Battlefield 1942 and other games perfectly fine).

  I can connect the laptop to an external monitor and that works very well also.

  If somone can help me with this that would be great.

  Also if it is to be dismantled then that would be nice.

• I have a View Sonic LCD 24 inch flat screen and it has a blue tint, how can I solve this problem?

  I have a View Sonic LCD 24 inch flat screen and it has a blue tint, how can I solve this problem?

  Hello

  He got this 1 day, or has it just begun?

  If it was always this way, it could be a manufacturing defect or your advanced display settings may be incorrect. The latter can be determined according to the settings/Advanced/display/personalization in the control panel settings. See Customization here, it varies depending on the manufacturer, but you focus on controls that adjust color output.

  If it has started, then it is possible the monitor had a malfunction. I put another monitor (if available) on the system. If the problem persists, then the fault is in the video card or display drivers. If it disappears, then the monitor can go wrong (you can try to adjust the settings on the screen itself to see if it has no effect). If it turns out to be the graphics card, I would like to firstly download and install a new set of drivers for the graphics card or the manufacturer of the system (the best for download, then uninstall the current set restart and install the new download).

• Blue screen in decline after replacing the screen

  I got my iPhone 6plus screen replaced at an apple store, earlier this week, and now a random regression a blue screen appears from the top of the screen and goes up and down, disappears, then pops up. Meanwhile, the screen is not sensitive to the touch, but when it stops and I double finger restart my phone several times, it works perfectly fine, then at random again. I've already set up another appointment on the apple store. What is an internal error and apple will charge me to fix this?

  It's either a problem with the screen replacement and Apple will not charge your for this or there is also damage to the logic board and you need to replace the entire phone. There will be an extra charge for this.

• My iPhone 6 s screen has suddenly had a green tint and the letters are blurry.

  I was watching netflix on my iPhone and then I suddenly noticed the screen get a slight green tint to it. I go to the home screen and notice that it is all green and the image is blurred. I did not drop the phone, so I don't know what's the problem with him.

  First of all restart the device by holding the home and power button until the Apple logo appears. If the screen is always off color take your device at the Apple store, that she be evaluated. Your device may still be under warranty. If there is a problem, Apple will repair or replace the unit. Do it now while the warranty is still in effect.
