Linear gradient in Photoshop CS3?

    Click on the gradient in the gradient tool settings at the top of the
    screen, and set the Smoothness slider to zero.

    Gradient smoothness has been with us since at least Photoshop 5.5. Even
    today, many discussions of this feature assume that the term smoothness
    means an even distribution of gradient values. The term actually means the
    opposite: the use of a spline function to weight the ends of the gradient so
    that color transitions within the gradient are smoother. At the time this
    feature was introduced, this was considered to be so superior to a linear
    gradient that there was no way to disable it! Photoshop 6.0 provided a way
    to control smoothness in the gradient editor.

    Problem: create a 256-px-wide grayscale picture, filled with a linear
    gradient from 0 to 255

    Settings for the gradient tool:

    Foreground to background
    Linear gradient
    Mode: normal
    Opacity: 100%
    Reverse: no
    Dither: no
    Transparency: no

    To my surprise, the resulting gradient is not linear. It seems like it
    is a bit squished toward the center, i.e., the edge color are a bit
    stretched.

    Any ideas?

    I do not know why you would not get a linear gradient with those
    settings. I do not have CS3 for testing but I tried it with CS2 and it
    worked fine.
    Unless the blend modes have changed from cs2 to cs3 then you can
    verify the linearity by duplicating the gradient and rotating it 90
    degrees and placing it in linear light blend mode at 50% opacity then
    add a threshold adjustment layer set to 128 - the line will be strait
    from corner to corner, if it is linear.
