Selective Editing Enhancements
Copy & Paste of Layers & Regions Create a layer on one image, and copy & paste that layer with its settings and regions to many other images.
Regions transform with image adjustments Regions are updated and change shape when settings to the overall image cause the image to change shape.
Added Layer Opacity to adjust the intensity of all the adjustments made on a layer with one simple slider.
Added Region Blending Modes to allow regions to be set as “subtractive” so that they de-select portions of the image to adjust.
