The Lasso Mask. Yes, I've read the Help on this but it's pretty thin on description about how it works and no examples. I'm familiar with the other masks (except Magnetic). I've played with it but it doesn't seem to do anything useful. Can anyone explain how/when/why it's used - because I'm baffled?
Here's a short guide.
The Lasso Mask Tool is similar to the Freehand Mask Tool but has a slight automatic advantage: it enables you to instantly select well-defined areas of color by adjusting the Tolerance value on the Property Bar, which controls sensitivity (see below).
Higher tolerance values reduce the color sensitivity, enabling you to select a wider array of color. Surround the area you wish to select, and double-click to end the session. In the example below, a hang glider on a blue sky background is easily selected with a tolerance value of 20.
I hope it helps
OK. I get it now. It relies on high contrast and, as in your example, a solid background. Otherwise, it's a bit hit and miss, depending on the tolerance. No wonder I couldn't get it to work. I think your example is probably the only real use for it. But many thanks for the reply Carolyn.
