The Lasso selection tool was introduced in Exposure X7.1. It is a great way to quickly generate detailed layer masks. We made this video to demonstrate how to use the Lasso tool, refine the selection, and use the layer mask to control editing adjustments.
If you want to select a defined object in Exposure, the Lasso tool is the perfect choice. Once the selection is made, there are several ways to refine the boundaries. Also in this video are suggestions on ways to improve the accuracy of the masks you create.
