Canon EOS 6D has problem with yellow tint lcd, i can't custom WB with lcd, when i see the image on lcd is warm but when i shooted and preview on macbook or iphone, this became blue than the lcd, what happened with my lcd, i bought it 2 week ago in Vietnam, i compared it with another 6D and my camera 6D is more yellow tint than another. Who can help me dicuss about it and how to fix theme? I feel sad now because it bought from my salary and i am a student in college! I search on Google and the image same my problem, my camera same with 5DSR.
You should not be adjusting the white balance (color temperature) of your camera based on the image you see on the LCD screen. You should not even adjust exposure based on the image you see on the LCD screen. The LCD review is only there to validate things such as composition, focus, subject didn't blink, etc. It's not there to analyze color or exposure.
Regardless of how the image appears on the LCD (which is not color calibrated) the image may (and probably will) look different on your computer screen (especially if you've color-calibrated your computer's display.)
If you want to know that you are getting accurate white balance, use a "gray card" -- a simple neutral gray surface. The card itself is a perfect neutral gray. You can take a photo of the card in the same lighting as your subject, then select "custom" white balance. It will ask you for a reference image and you select the image of the gray card. The camera will analyize the pixel colors (knowing that they should have equal amounts of red, green, and blue if they are truely gray) and determine if the pixels are tinted (favoring any particular color component). This allows the camera to detect that the light itself is creating a color cast and it can neutralize that color cast.
I prefer to shoot RAW. In RAW, the camera doesn't apply white-balance correction in the camera -- that's done on the computer. But I shoot a single frame with the gray card in it so I can use it as the neutral reference to color correct all the other images.
On my first DSLR (after shooting film for years) I noticed the images look rather underexposed, so I boosted the exposure. It turns out they weren't underexposed and I should have trusted my exposure settings and light meter and not the display. The dispay itself was simply set too dim.
Oh. I think my lcd have problem because it not same K temperature. I use 2 6D to compare with same setting... and then i copy it to macbook... macbook screen same with 6D not my... so i can't use my 6D to set K temperature. i want to set K to recording movie clip
You can still set your camera's custom white balance with a grey card before you begin shooting video. See page 121 of the 6D instruction manual.
