Hue/Saturation/Lightness

The HSL control in PhotoImpact is a simplified version of that in Photoshop, but ends up being more complicated.

In PS, you can select, for example, just to change the HSL of the Reds. It looks like this is the same in PI as setting the Method to Range and then setting the 4 sliders to the red part of the range. What each of the 4 points does is not explained. In PS, the sliders are given a default setting, just by selecting the Reds.

One of the differences between PI and PS is the scale used for each slider. PI uses a range of -180 to 180 for Hue. PS uses a range of 50 to -50 for Hue.

To convert a PS value to PI, use this formula:
PI value = (-3.6 * PS value)

For Saturation and Lightness, PI uses a range of -100 to 100. PS uses a range of 50 to -50.

To convert a PS value to PI, use this formula:
PI value = (-2 * PS value)
