The Clean and Creative Advanced Workflow Collection is what you've been waiting for! This set gives you the ability to create clean edits, then "layer" creative presets to produce your own signature style. Use the eight "base" presets to give your image a clean edit, then select from each of the six levels of preset groups for the perfect look. With forty-one presets in this collection, all which can be mixed-and-matched, you can create an unlimited number of custom combinations for your images.
