    Calibration bar at the bottom of the page

    Observant lot you all are...

    There is a new calibration bar at the bottom of the screen...



    For those with calibrated monitors you should see 33 distinct bars of brightness.
    If either end are continuous black or white then you are not seeing images as they should be.

    For those who don't ... click the bar for more information.

    From Rick:
    The best method I have found for manual calibration is here

    reminder: The calibration bar does NOT mean your monitor is correctly calibrated. It just means that the brightness levels are correct, nothing more.

    To ensure your monitor is correctly calibrated, the use of a hardware device is necessary. Please do not assume that because you can see all the squares on our calibration bar, that you do not need to use a monitor calibrator. Use of a hardware calibration device is the only way to get it right!


    Just cause you can see all the bars does not mean your screen is OK.

    Never scroll down that far Kym , But a handy little things these are , I get 34 graduations
    Lol , I keep on losing count, Maybe a couple more, But the important thing is I can see them all , Especially at both ends

    Yes to calibrate correctly, you need a spider, have seen them on e-bay at reasonable prices.

    I sort of glanced at it and 4-got, but since you remind me, I'm glad I can see each division separately. I hope that means this monitor is not 1/2 bad after all.
    Ta 4 that, Am.
    CC, Image editing OK.

    32 gaps, 33 bars

    If they are all distinct then you are half way to a calibrated monitor

    If you find that the left hand few all look the same (black), or the right hand ones are all white, and you cannot see any graduation between them, your monitor needs calibrating. The optimal way is with a hardware colorimeter calibration device, like a Spyder. If you do not have access to one, the best method I have found is here

    Line look OK and distinct on an iPad. I doubt I can do any calibration on of anyway.

    iPads etc can be calibrated with the latest hardware calibration devices

    Doesn't work. Not even at all.

    It's much brighter at the right-hand end.

    Still looks fine to me , Now I've recounted, Cause it's bright at the right hand end , thats the white end , But you should be able to see a definate graduation in the whites ( For Highlights) Same as the other end , Blacks, ( Definition in the Shadows) Your Calibration must be way out

    I thought that you were in favour of ETTR (expose to the right)

    OH! is that what this was for!!

    I was tapping it lightly with my tablet pan expecting to hear soft melodic tinking sounds. What a relief, as I thought my sound card had bitten the dust or something.

    Are you sure it's not simply a lot darker at the left hand side instead??

    damn it's hard to see that black wedge against a black background too!

    Get a new monitor, Or you need to calibrate by the sounds of that , You should be able to see each separate segment , But there is more to it than just this little quick test

    Although this bar gives you a good indication if your monitor is set to display various brightness levels, it is still missing the concept of temperature (kelvin). Even if you can see all of the small bars and the graduations of each one from black to white, your monitor could still be less than accurate. It could be displaying the graphic with a warm (reddish) tone or a cool (blueish) tone. Sometimes this is very hard for the human eye to realise cause the brain is smart enough to know and make you think you are seeing white, when really what is visible is not white. The brain fills in the gaps and makes us see what it thinks we need to see, not necessarily what is really in front of us.

    So use this graphic for what it is, but do not assume your monitor is calibrated correctly, just cause you can see every bar in the graphic.

    Sigh.

    Even - "free from variations or fluctuations". It wasn't that obscure.
