  1. It all depends on how accurate you want the color to be. If you can do it by eye and its

    good enough then great. If your more serious then even a good camera white balance

    wont solve the issue as you can have a cast in the shadows, a different one in the mids,

    and again a different one in the highlights. If you cant use a grey card then you will have

    to do the best you can with what the image provides.

     

    I find something i know should be grey or white, and something i know should be black.

    Sample the RGB levels of each, and use a levels adjust layer to correct the cast in the

    shadows and the heighlights. If you have a series of images shot at the same time to do

    save the levels adjust and apply to the other images, or create a droplet to save time.

  2. Ok i can tell you how it works in pro and hopefully that will help you.

     

    launch the program and click next until it comes up with a screen that says "current

    settings"

     

    Select change these settings

     

    Go through to the "select target" window and select new at the bottom

     

    It then goes through gamma, white point etc

     

    You then come to "select luminance mode" with the choice of visual or measured.

    Chose measured

     

    This will then get you to input the brightness that you want between 100 to 120 is good.

     

    Now that you have changed that it should ask you to adjust the contrast and brightness in

    the calibration.

     

    I usually leave the contrast and only use the brighess on my display, but it might be

    different for you

     

    If this isnt in spyder2 then hopefully you will have a tools menu at the top of the screen.

    Click tools>colorimeter

     

    This should then bring up a calibration box. You can then take readings and adjust the

    brightness on you CRT until the readings read between 100 and 120. You can see the

    brightness in the CIE Luv window. It has a L at the end of the number.

     

    Let me know if this works for you.

  3. Hi Allen, i use a spyder2 and software on my laptop display. The color never gets that goos

    on them, but i found by using basiccolor software instead it got slightly better. I have my

    brightness set at 100%, and its still nowhere near bright enough.

     

    For the crt, when you run the spyder software are you telling it to measure the luminance, or

    just doing it visually?

  4. i have just used basiccolor on a 1990sxi, and it was a massive improvment to the spyder

    software that i was using. It didnt give me the option to fully hardware calibrate, but it

    looks like it has done something to the monitor.

     

    At 100% brightness the monitor used to read roughly 270lux, so to get it to 100lux i had

    to take it down to around 40%. After using basiccolor at 100% brightness it is reading

    100lux.

     

    Am i right in thinking that this is what hardware calibration would do?

     

    And will it have done this to the color temp etc as well?

  5. Hi mike, if your getting into digital photography then there is no real point in getting an

    apple display. The controls on the monitor are very very limited, and the display its self is not

    very colour accurate at all. For the same price, and often cheaper you can get a far better

    monitor. Try the NEC Multisync range, and the mid range Iiyama monitors are very good as

    well. These will last you longer if you ever start to get more serious about photography, so

    are a better investment!

  6. Hi guys

     

    Ok ive just got the nec 1990sxi, which i was told was amazing. So i tried to calibrate it using a spyder2

    pro, but the r/g/b/y/m/c guns dont make a difference to the screen, the only thing that does are the

    preset color temps, any one else had this? or have any experience with these monitors who can help?

     

    At the moment i mite as well have brought the cheaper model as mine has no better features!

     

    Thanks in advance
